2026 New Zealand election: Flood protection, insurance and recovery on the Heretaunga Plains

For a household on the Heretaunga Plains, the question is bigger than which party promises to spend more on flood protection. It's about whether your home will remain safe and insurable over the coming decades, whether your rates and insurance premiums will become more expensive, and whether your family will receive timely support if another major flood occurs.

The key issues to compare across parties are:

• Long-term flood protection: Who will pay for stopbanks, river management, drainage improvements and other flood-resilience infrastructure in Hawke's Bay?
• Household costs: Will central government contribute, or will more of the financial burden fall on councils, ratepayers and individual property owners?
• Insurance and property values: What will parties do about rising premiums, insurance exclusions and homes that become difficult to insure or sell?
• Recovery after a disaster: What financial support would be available for damaged homes, temporary accommodation and families whose lives are disrupted?
• Future development: Will new housing be restricted in high-risk areas, and how will existing homeowners be treated if their properties face increasing flood risk?

For families with school-age children, there's another consideration: whether flood planning protects not just individual houses, but also roads, schools, water supplies and the wider community your family depends on.

I'll distinguish between established government decisions, parties' documented positions and proposals that would still need funding or legislation. That's particularly important for the 2026 election, because a policy announcement is not the same as a funded commitment to protect a specific property.

1. What is already happening in Hawke's Bay?

Before comparing election promises, it's worth establishing what your household's future may depend on regardless of which party forms the next government.

The current flood-protection programme

Hawke's Bay Regional Council is delivering a multi-year flood-resilience programme covering seven major projects:

• Ōhiti Road–Omāhu
• Pākōwhai
• Pōrangahau
• Waiohiki
• Wairoa
• Whirinaki
• Havelock North, delivered by Hastings District Council

The programme includes improvements to stopbanks, pump stations, drainage infrastructure and flood-monitoring systems.

The funding arrangement for these projects is $256.5 million: $209 million from central government and $47.5 million from Hawke's Bay Regional Council. The regional council has also noted that it bears the cost of projects exceeding their allocated budgets. That distinction matters because construction delays or cost overruns could affect the local financial burden. Source: Hawke's Bay Regional Council, Restoring Flood Resilience.

These projects are intended to reduce flood risk, but they should not be interpreted as a guarantee that every property on the Heretaunga Plains will be safe from future flooding.

What the government has already committed to

Following Cyclone Gabrielle in 2023, the Labour-led government established a national framework for sharing the cost of recovery and flood mitigation.

Under the arrangements announced in 2023:

• Category 3 properties, where risks could not be sufficiently mitigated, could qualify for voluntary buyouts, with the Crown and councils sharing the net cost.
• Category 2 properties, where risks could potentially be managed through protective measures, could benefit from co-funded mitigation works.

Hawke's Bay's agreement included a Crown contribution of 50% of the net cost of eligible Category 3 buyouts and a commitment of $203.5 million towards flood-protection projects for Category 2 properties. Sources: New Zealand Government, 1 June 2023 and 3 August 2023.

The current government's wider cyclone recovery programme also includes central-government and council co-funding for buyouts, mitigation projects and transport infrastructure. Source: National Infrastructure Funding and Financing.

Why this matters to your vote: the next government will inherit existing projects and financial commitments. The important question is whether it will maintain them, extend them where necessary and establish a sustainable funding system for future protection.

2. How the main parties compare

The most important distinction is between parties' records in government and their specific commitments for the next parliamentary term.

As of 16 October 2026, I could verify the existing Hawke's Bay funding programme and find the parties' election-policy resources, but I could not establish a complete set of costed, party-specific flood-protection commitments for the Heretaunga Plains. I won't treat a general climate policy or an infrastructure announcement as proof of a commitment to fund your local flood defences.

Here is what the available evidence establishes.

National Party

Relevant record: The National-led coalition is responsible for the current phase of government and council flood-resilience investment.

• Long-term protection: The existing central-government-funded programme is being delivered under the current government. The regional council's projects are intended to strengthen defences against future severe weather. Hawke's Bay Regional Council
• Household costs: National's published 2026 policies include a commitment to keeping rates affordable and maintaining fiscal discipline. Those objectives do not, by themselves, establish how future flood-protection costs would be divided between central government and local ratepayers. National's 2026 policies
• Insurance: The government has a national adaptation programme and is considering the relationship between residential insurance and climate-related hazards. I could not verify a National election commitment guaranteeing flood insurance availability or limiting premiums for Heretaunga Plains households. Treasury's residential insurance work

What this could mean for your household: The existing projects provide a concrete starting point. The election question is whether National would maintain and extend central-government investment beyond the projects already funded, and how much of any additional cost would fall on ratepayers.

Look for a specific commitment covering ongoing maintenance, future upgrades and the consequences of construction cost overruns—not just a commitment to build infrastructure.

Labour Party

Relevant record: The Labour-led government established the 2023 framework for sharing the costs of voluntary buyouts and flood mitigation following Cyclone Gabrielle.

• Long-term protection: Labour's record includes the funding arrangements that helped establish the existing Hawke's Bay recovery and protection programme. The original framework included Crown support for both eligible buyouts and mitigation works. New Zealand Government, 2023
• Household costs: The previous framework demonstrated a willingness to share some disaster-recovery costs between central government and councils, rather than leaving all costs to local communities.
• Insurance and recovery: The 2023 arrangements recognised that some properties could be protected while others faced risks that could not be sufficiently mitigated. The framework provided different pathways for these circumstances.

What this could mean for your household: The key question is whether Labour would extend the principle of central-government cost-sharing to additional flood protection, future maintenance and households affected by new risk assessments.

I could not verify a current Labour election commitment specifying a new Heretaunga Plains flood-protection budget, a household insurance subsidy or a guaranteed post-disaster compensation package. Its previous record should not be mistaken for a promise that the same funding arrangements will automatically be extended.

Green Party

Relevant policy direction: The Green Party's broader environmental approach includes climate adaptation and nature-based approaches to managing hazards.

The 2026 election policy resources identify nature-based hazard mitigation as a policy proposal associated with the wider environmental debate. However, I could not verify a specific, costed Green Party commitment for the Heretaunga Plains' stopbanks, drainage systems or insurance costs. 2026 election policy comparison

For your household, the practical questions are:

• Would the party support continued investment in engineered flood defences where these are necessary to protect existing communities?
• Would it fund complementary measures, such as restoring wetlands or creating areas where floodwater can safely spread?
• Would it provide central-government funding so that nature-based solutions do not simply create another cost for local ratepayers?

Nature-based approaches can complement engineered protection, but they are not a substitute for demonstrating that a particular community's flood risk will be adequately managed.

What this could mean for your household: It is worth examining how a party's environmental approach translates into specific protection for existing homes, particularly if you want to remain in your current property for decades.

ACT New Zealand

ACT's 2026 election materials are available through its official website, but I could not verify a specific, costed commitment covering long-term flood protection on the Heretaunga Plains.

For your household, three questions would help clarify ACT's position:

• Would it maintain or increase central-government contributions to flood-protection infrastructure?
• Would it place more responsibility for protection and maintenance on local councils or individual property owners?
• What would it do about homes that become difficult to insure despite the owners taking reasonable precautions?

The answers matter because a commitment to controlling public expenditure does not, on its own, establish whether your household's eventual costs would be lower. The outcome also depends on future insurance premiums, council funding decisions and the damage avoided through effective protection.

New Zealand First

New Zealand First's election policies can be explored through its official website.

I could not verify a specific, costed 2026 commitment to additional flood protection for the Heretaunga Plains or a new national scheme to protect householders against flood-related insurance costs.

For this party, it would be useful to establish whether it would support:

• Additional central-government investment in regional flood protection.
• Long-term maintenance funding, rather than capital funding alone.
• A defined national approach to disaster recovery and the division of costs between the Crown, councils and property owners.

These details would help distinguish general support for regional infrastructure from a commitment that would make a measurable difference to your household.

Te Pāti Māori and other parties

Te Pāti Māori and the smaller parties contesting the election should also be considered if their wider policies align with your priorities.

I could not verify sufficiently specific, costed commitments from these parties to compare their proposed Heretaunga Plains flood-protection spending or household insurance assistance on a like-for-like basis.

For Te Pāti Māori, one relevant question is how disaster-recovery policies would address the needs of Māori landowners, marae and whānau affected by flooding, alongside the wider community.

For smaller parties, the practical test is whether they have a published proposal that identifies the funding, eligibility rules and delivery arrangements—not simply a statement supporting climate resilience or regional development.

You can explore the registered parties and their published positions through the 2026 Policy.nz election guide.

3. What the differences could mean for your household

Party names matter less than the details of the policies that would affect your property. Four policy choices deserve particular attention.

A. Who pays for flood protection?

Imagine that your local area needs another substantial upgrade after the currently funded works are completed.

There are three broad approaches a government could take:

Funding approach	Potential benefit for households	Main concern
Greater central-government contribution	Spreads costs across the national tax base rather than relying entirely on local ratepayers.	Competes with other national spending priorities.
Greater reliance on council rates	Allows regional and district councils to fund projects suited to local needs.	Households could face substantial increases in rates.
Greater reliance on property owners or targeted charges	Connects some costs to the properties receiving protection.	Owners could face additional expenses even when flood risk is partly beyond their control.

These are possible funding approaches, not a claim that every party has adopted one of them.

For the Heretaunga Plains, I would look particularly closely at whether a party specifies:

• A continuing Crown contribution after the current projects are completed.
• Who pays for future maintenance, replacement and upgrades.
• Whether funding is guaranteed for the life of the infrastructure or allocated one project at a time.
• How cost overruns will be handled.

The distinction between construction and maintenance is important. A new stopbank does not eliminate the need to maintain and eventually upgrade it.

B. Will protection help keep your home insurable?

Flood risk and insurance availability are closely connected.

The Treasury has acknowledged that increasing flood risk can affect the insurability of homes and create wider costs for homeowners and society. Its work on residential insurance is considering the relationship between insurance and climate adaptation. Source: New Zealand Treasury

For your family, there are three distinct questions.

Will the flood risk be reduced?

A well-designed and maintained flood-protection scheme may reduce the risk to a property. However, protection levels vary, and no flood-protection system can guarantee that flooding will never occur.

Will insurers recognise that reduced risk?

Even after infrastructure improves, an insurer's decision will depend on its assessment of the property's residual risk and the terms of its policies. You should not assume that completing a stopbank automatically means lower premiums or unchanged cover.

Will the government help if cover becomes unaffordable?

This is where a specific election commitment would be valuable. Possible policies could include assistance with eligible mitigation work, a clearer national framework for sharing disaster costs, or measures addressing insurance availability.

I could not verify a current, costed commitment from the main parties guaranteeing affordable flood insurance for households on the Heretaunga Plains.

When comparing their policies, look for actual proposals addressing insurance availability, premium affordability, excesses and exclusions. A general promise to improve climate resilience does not resolve these questions.

C. What happens if another major flood occurs?

The 2023 recovery arrangements provide a useful example of how governments can distinguish between different levels of risk.

Situation	Existing policy precedent	What to look for in new commitments
A home can remain safely occupied with appropriate protection	Category 2 mitigation funding	Will further mitigation be funded if risk remains high?
A home faces a risk that cannot be sufficiently mitigated	Category 3 voluntary buyout arrangements	Will there be a future buyout pathway, and how would compensation be calculated?
A home is damaged in a future flood	Insurance and applicable disaster-recovery arrangements	What support would be available for uninsured losses, temporary accommodation and rebuilding?
A community's roads and essential infrastructure are damaged	Government-supported regional recovery programmes	Will funding be available quickly enough to restore access to schools, work and essential services?

The historical Category 2 and Category 3 arrangements were designed for properties affected by the North Island weather events. They should not be treated as a guarantee that the same eligibility criteria or financial support will apply after every future disaster. Source: National Infrastructure Funding and Financing.

For your family, the key issue is whether the next government would establish a predictable system before another disaster occurs.

A clearly defined recovery framework could reduce uncertainty about eligibility, compensation and who pays. Without one, households may face uncertainty about their financial position at the same time they are trying to find somewhere to live and keep their children at school.

D. What about schools, roads and essential services?

A home may escape direct flooding while the family is still significantly affected by a disaster.

Flooding can disrupt:

• Roads and school transport.
• Access to schools and childcare.
• Drinking water, wastewater and electricity.
• Access to shops, workplaces and healthcare.
• The availability of temporary accommodation for displaced families.

For this reason, flood protection should not be assessed solely by the number of houses behind a stopbank.

Ask whether parties' plans cover the wider resilience of the communities where families live, including the infrastructure needed to maintain everyday life after an extreme weather event.

---

4. What should you check before voting?

Given your concerns about your home, insurance and children, I would use the following questions to examine each party's policies.

Question to ask	Why it matters to your household
Is there a specific commitment to Hawke's Bay flood protection?	Distinguishes regional commitments from general infrastructure promises.
How much will central government contribute, and for how long?	Helps you assess the potential future burden on rates and household finances.
Who pays if construction costs rise?	Cost overruns could affect council budgets and local ratepayers.
Is ongoing maintenance funded?	Protection needs to be maintained throughout its useful life.
What is the plan for homes that remain at high risk?	Some properties may need additional mitigation or a different long-term solution.
Is there a policy for flood-related insurance affordability?	Better protection does not automatically guarantee affordable cover.
What assistance is available after a future disaster?	Determines how much uncertainty families may face when recovering.
Will schools, roads and essential services be included in resilience planning?	Community resilience matters even when a family's home is not directly damaged.

You can check published party policies through Policy.nz's 2026 election guide. The National Adaptation Framework is also relevant because it addresses risk information, responsibilities, investment in risk reduction and cost-sharing before and after disasters.

5. What you can do now, regardless of the election outcome

There are a few practical steps that could help your family assess its exposure while the political debate continues.

Check the flood risk for your specific property. Hawke's Bay Regional Council provides flood hazard modelling and related information. A regional flood map is a starting point, but it is not a substitute for a property-specific assessment.

Ask your insurer specific questions. Confirm whether your current policy covers flood damage to the house and contents, what excesses apply, and whether any exclusions or special conditions relate to flooding. If you are considering renovations or protective work, ask whether these changes could affect your cover.

Find out which protection projects affect your area. The regional council's Restoring Flood Resilience programme provides project information and progress updates. Ask what level of protection is intended, what residual risks remain, and how maintenance will be funded.

Plan for school and household disruption. Identify alternative routes to school and work, establish a family communication plan, and keep essential documents and insurance information accessible. These steps do not replace public flood protection, but they can reduce disruption during an emergency.

---

My overall assessment

For the 2026 election, the central issue for a homeowner on the Heretaunga Plains is whether a party can explain how it will fund long-term flood protection and manage the financial consequences of residual risk.

The existing programme gives you a concrete basis for evaluating the parties: substantial Crown and council investment is already under way, but it does not eliminate flood risk. The 2023 recovery arrangements also show that central-government cost-sharing can make a material difference to affected households.

The available evidence does not support a reliable ranking of the parties on your specific concerns. In particular, I could not verify sufficiently detailed, comparable 2026 commitments on future Heretaunga Plains protection, household insurance costs and disaster compensation to say which party would deliver the greatest financial benefit to your family.

Instead, I would concentrate on three distinctions when reading the parties' promises:

1. Funding already committed versus new funding promised. Existing projects matter, but so does what happens after they are completed.
2. Reducing flood risk versus managing the cost of remaining risk. Infrastructure, insurance and recovery support address different problems.
3. General commitments versus enforceable, costed plans. A credible proposal should identify the funding, responsibilities, timetable and households eligible for assistance.

Those distinctions should help you assess what each party is actually offering your household, without relying on broad assurances about either economic management or climate resilience.

2026 New Zealand election: flood protection for the Heretaunga Plains

For a homeowner in Hastings with school-age children, the flood-policy question is about more than stopbanks. It is whether your home can remain safe and insurable over the next 20–50 years, whether rates and taxes will fund the necessary infrastructure, and what happens financially if another major flood makes your house uninhabitable.

The key issues to compare across parties are:

• Long-term protection: stopbank upgrades, river capacity, drainage, floodwater storage and the maintenance of existing defences.
• Who pays: central government, Hawke's Bay Regional Council, Hastings District Council, and ultimately households through rates, taxes, levies or insurance premiums.
• Recovery support: grants, buyouts or relocation assistance, temporary accommodation, and help rebuilding after a major flood.
• Insurance and future insurability: whether policies address flood risk through risk reduction, clearer risk information and support for households that face rising premiums or exclusions.
• Planning for children’s future: whether new housing and existing neighbourhoods can remain viable as flood hazards and climate risks change.

One important distinction: a promise to invest in flood protection is not the same as a funded, engineered project with a construction timetable. For your household, the location of the proposed works, their design standard and the funding arrangements matter just as much as the headline spending figure.

1. What is already funded in Hawke’s Bay?

The Council has identified a need to review and upgrade the scheme for future climate risks. Resilient River CommunitiesHawke's Bay Regional Council Three-Year Plan 2024-2027

These are existing programmes, not necessarily new commitments for the next government. Also, the regional programme's $256.5 million and the wider recovery package's approximately $203 million are different funding descriptions; they should not simply be added together as if they were entirely separate pools of money.

A further issue is affordability. In September 2025, the Regional Council said that implementing all the engineering options under consideration could cost $600 million and potentially double rates if funded entirely by ratepayers. That was a scenario illustrating the scale of the challenge, not an adopted bill for every household. Hawke’s Bay community to help shape flood resilience future | News & Media

2. How the parties compare

The 2026 election is scheduled for Saturday, 7 November 2026. The important distinction below is between a party's documented national approach and a specific, funded promise for the Heretaunga Plains. The latter is what you should look for in campaign announcements and costings. Candidate and party lists releasedThe main parties vying to form New Zealand's next government

Policy information checked against sources available on 15 October 2026. Where a party-specific Hawke’s Bay commitment could not be verified, that is stated rather than assumed.

National Party

Current governing party

• Flood protection: National's government has supported the existing Crown-funded recovery and flood-resilience programmes. These provide a real funding base for regional works, but do not by themselves settle the full future investment needs of the Heretaunga Plains. Cyclone Recovery Funding Hawke's BayRestoring Flood Resilience
• Long-term direction: The government's National Adaptation Framework sets out national work on risk information, responsibilities, investment in risk reduction, and the sharing of costs before and after disasters. It also envisages adaptation planning in priority locations. National Adaptation frameworkClimate Change Response Amendment Bill
• Household implications: Existing funded works can reduce risk in the areas they cover. The unresolved questions are how much additional protection will be funded, how much councils and ratepayers will contribute, and what assistance households will receive if protection is insufficient.
• What to verify: A new commitment to the Heretaunga Plains scheme, its funding beyond current programmes, and any specific support for households facing flood-related insurance difficulties.

National's published 2026 policy page also emphasises fiscal restraint and keeping rates affordable. The key question is how those goals would be reconciled with the additional flood infrastructure the region may require. 2026 Election PolicyHawke’s Bay community to help shape flood resilience future | News & Media

Labour Party

• Flood protection: Labour says its previous government created a $6 billion national resilience fund following Cyclone Gabrielle, intended to help communities become more resilient, including through flood-protection infrastructure. Labour criticises the current government's decision to discontinue that funding approach. 2026 Election Q&A - Science
• Long-term direction: The central policy difference to examine is whether Labour would restore a dedicated national resilience funding mechanism and how it would allocate funding between regional infrastructure, transport links and other resilience needs.
• Household implications: A renewed national fund could provide a route to financing works that would otherwise place more pressure on regional rates. But the benefit to a particular Hastings property would depend on the new fund's rules, the amount allocated to Hawke's Bay, and whether the funding is additional to existing commitments.
• What to verify: Labour's specific 2026 funding pledge, whether the previous fund's scale or structure would return, and whether it has a new policy for flood-damaged or difficult-to-insure homes.

The $6 billion figure describes Labour's account of its previous national resilience fund; it should not be read as $6 billion earmarked for Hawke's Bay or as a confirmed new election commitment. 2026 Election Q&A - ScienceLabour's 2026 Election Policies

Green Party

• Flood protection: The Greens support a national climate-adaptation framework with credible and fair funding, proactive planning before disasters, and partnership with iwi Māori. They argue that adaptation costs should not fall disproportionately on the people most exposed to climate risks. 2026 Election Q&A - ScienceManifesto 2026
• Long-term direction: Their approach places particular emphasis on planning ahead, climate adaptation and nature-based approaches alongside other measures. For Hawke's Bay, these would need to be considered alongside engineered stopbanks, drainage, pumping and river management.
• Household implications: The financing model could matter if you are concerned about rates increasing to pay for protection. The practical benefit would depend on how national funding is distributed, how much is allocated to hard infrastructure, and whether household assistance is included.
• What to verify: A costed Heretaunga Plains programme, the proposed national/local cost split, and any explicit commitment to flood insurance or relocation support.

The Greens' stated approach offers a clear framework for sharing adaptation costs, but that alone does not establish a particular level of protection or a grant entitlement for your property. Manifesto 2026Hawke’s Bay community to help shape flood resilience future | News & Media

New Zealand First

• Flood protection: In its 2026 election science Q&A, NZ First supports a $1.2 billion Regional Infrastructure Fund that includes flood protection, water storage and other regional infrastructure. It also proposes restoring local Catchment Boards to manage rivers, streams and flood protection. 2026 Election Q&A - Science
• Long-term direction: Its emphasis is on regional infrastructure and more direct catchment-level management.
• Household implications: This approach could be relevant to river management and regional investment. However, the published national figure covers multiple types of infrastructure across regions; it is not a dedicated Hawke's Bay flood-protection allocation.
• What to verify: The amount Hawke's Bay would receive, whether the fund is new or overlaps existing programmes, and how Catchment Boards would interact with the Regional Council's current responsibilities.

ACT New Zealand

• Flood protection: ACT is part of the current governing coalition. The existing government's national adaptation work and regional recovery funding therefore provide relevant context, but they should not automatically be treated as a separate ACT policy pledge. National Adaptation frameworkCyclone Recovery Funding Hawke's Bay
• Long-term direction: The decision-relevant question is what ACT would specifically commit to funding, regulating or changing in the allocation of responsibilities between central and local government.
• Household implications: The effects on your rates, flood protection and recovery entitlements cannot be determined from coalition membership alone.
• What to verify: ACT's own 2026 flood-adaptation policy, any proposals for national versus local cost-sharing, and its position on public assistance after major floods.

I could not verify a specific, costed ACT commitment for the Heretaunga Plains in the sources reviewed.

Other parties

The Opportunity Party (TOP) and Te Pāti Māori are also contesting the election. Their broader positions on tax, housing, community investment and environmental issues should not be confused with a specific commitment to fund stopbanks or compensate flood-affected homeowners. The sources reviewed did not establish a sufficiently detailed, costed Heretaunga Plains flood-protection commitment from either party to compare directly with the proposals above. The main parties vying to form New Zealand's next governmentCandidate and party lists released

3. What these differences could mean for your household

The effect on your family depends on whether you live in an area protected by proposed upgrades, an area where residual risk remains high, or a location where authorities may eventually consider retreat or relocation.

Issue	What to look for in party policies	What it could mean for you
Stopbanks and river works	Named projects, engineering standards, deadlines and secured funding	The level of residual flood risk after works are completed
Rates and taxes	Central-government contribution versus local cost-sharing	Whether protection means higher regional or district rates
Insurance	Risk-reduction commitments and treatment of high-risk properties	Future premiums, excesses, exclusions and availability of cover
Recovery after flooding	Clear eligibility for grants, accommodation, repairs or buyouts	How much financial loss your family might have to absorb
Schools and community infrastructure	Protection for roads, schools, utilities and evacuation routes	Whether children can get to school and essential services after a major event
Long-term property value	Updated hazard maps, planning rules and adaptation pathways	Whether your home remains financeable, saleable and insurable

Why the engineering standard matters

The Regional Council has been reviewing the Heretaunga Plains and Upper Tukituki schemes to consider higher protection levels, nature-based solutions and other ways of reducing risk. The existing scheme review has considered moving from protection against a 1-in-100-year river flood event towards a 1-in-500-year event. That is a planning objective discussed in the programme, not a guarantee that every property will receive that level of protection. Resilient River CommunitiesHawke’s Bay community to help shape flood resilience future | News & Media

A 1-in-100-year event means a flood with an estimated 1% chance of occurring in any given year, not one that happens only once every century. Under the simplifying assumption of a constant annual probability, the chance of at least one such event over a 30-year period is about 26%. For a 1-in-500-year event, the equivalent probability is about 5.8%. Actual risk can change with climate, river conditions, and the performance of flood defences.

That distinction matters because even a substantial stopbank upgrade cannot eliminate all risk. Drainage capacity, water backing up behind defences, erosion, breaches and the routes available for floodwater all affect what happens to individual properties.

4. Insurance and recovery: the gaps worth watching

The national adaptation framework is especially relevant to homeowners because it addresses not just infrastructure but also the sharing of costs before and after disasters. A national flood map is expected in 2027, bringing together national, regional and local hazard information. National Adaptation framework

However, better flood maps are not insurance guarantees, and a national adaptation framework is not the same as a universal guarantee of compensation.

For each party, look for explicit answers to these questions:

• Will the government contribute more to flood protection, or will councils and ratepayers carry most of the additional cost?
• Will there be a standing national recovery fund, rather than negotiations over emergency assistance after each disaster?
• If a home remains at high risk despite new defences, will owners have access to voluntary buyouts, relocation support or other assistance?
• Will there be any mechanism to improve access to insurance for households that have taken reasonable steps to reduce their risk?
• Will the government publish clear rules about who pays for rebuilding, and who bears the loss when rebuilding is no longer considered appropriate?

For context, the post-Gabrielle recovery agreement provided for government and council funding to share the cost of purchasing residential properties or property rights in Category 3 areas, generally at 50% each after insurance proceeds were accounted for. That was a specific recovery arrangement, not an ongoing promise that every future flood loss will be compensated in the same way. Cyclone Recovery Funding Hawke's Bay

5. What you can check before voting

The most useful local source is the Regional Council's Restoring Flood Resilience programme. It explains current projects and their funding. The Council's reducing flood risk information also covers hazard information, evacuation planning and the review of major flood schemes.

For party-specific commitments, compare the official National policies, Labour policies, Green Party manifesto, and ACT policies. NZ First's published regional-infrastructure commitments can be explored through its official website. For a wider comparison, Policy.nz's 2026 election guide allows you to explore parties' environmental and climate-adaptation policies.

When reading these, distinguish between an announced policy, a costed commitment, an appropriation approved in the Budget, and money already contracted for construction. They are not interchangeable.

Bottom line

For your home on the Heretaunga Plains, the most consequential difference between parties may be how they propose to pay for the next generation of flood protection and what they promise households when protection cannot eliminate the risk.

National's record includes the current government's adaptation framework and existing regional recovery investment. Labour points to its previous national resilience fund. The Greens emphasise fair national cost-sharing and proactive adaptation. NZ First highlights regional infrastructure investment and catchment management. ACT's specific commitments on local flood protection and recovery need to be assessed separately from its role in the current coalition.

Those are meaningful differences in approach, but they do not yet establish a directly comparable, fully costed plan for every part of the Heretaunga Plains.

Given that you have children of school age and are thinking about the long-term security of your home, it is worth examining both the proposed protection standard and the financial safety net if that standard is exceeded. Neither a new stopbank nor a general promise of disaster support answers both questions.
