We own a home on the Heretaunga Plains in Hawke's Bay and have school-age children. Flood risk, insurance and the cost of protecting our home are major concerns for us. I am considering my vote in the 2026 New Zealand general election. How would parties share the cost of flood protection between central government, councils and affected homeowners, and what are the trade-offs for our family?
Flood protection and the 2026 election: who pays, and what does it mean for Heretaunga Plains homeowners?
For your family, the central election issue is not simply which party promises to build more stopbanks. It is who carries the financial risk when protecting a community becomes increasingly expensive, and what happens to homeowners whose properties remain exposed despite those investments.
There are three separate costs to consider:
- Prevention: stopbanks, floodways, drainage, river management and warning systems.
- Recovery: repairing damage, emergency assistance and potentially buying out homes that cannot safely remain occupied.
- Household exposure: insurance premiums, excesses, exclusions, property values, rates and the cost of protecting your own property.
These costs can fall on central government taxpayers, local ratepayers and individual property owners in quite different proportions.
An important starting point: New Zealand's existing system already involves all three, but it does not guarantee that a homeowner will be fully protected or compensated.
1. How the existing system divides the costs
New Zealand's flood protection system is primarily administered locally.
| Participant | Main responsibilities |
|---|---|
| Central government | National policy, emergency response, legislation and contributions to major resilience projects |
| Regional councils | River management, major stopbanks, flood-control schemes and catchment planning |
| District and city councils | Local stormwater infrastructure, land-use planning and some local drainage |
| Homeowners | Private property drainage, property-level protection, insurance and residual financial risk |
Regional councils commonly use targeted rates to fund flood protection. This means people and properties benefiting from a scheme can pay towards its construction and maintenance.
The problem is that a major flood protection project can benefit an entire community while imposing substantial costs on a relatively small group of ratepayers.
Te Waihanga's National Infrastructure Plan identifies this affordability problem as a weakness of the traditional beneficiary-pays approach. It also documents the increasing role of central government funding. Sector summaries: Flood protection | National Infrastructure Plan
What this means on the Heretaunga Plains
9
The Heretaunga Plains Flood Control Scheme protects much of Hastings, Flaxmere, Havelock North and Napier.
It covers approximately 39,000 hectares, with around 138,000 people within its boundary.
A major resilience objective is to improve protection from a current 1-in-100-year flood standard towards a 1-in-500-year standard at identified locations. Heretaunga Plains Flood Control Scheme - Hawke's Bay
That is a substantial improvement, but it does not mean every home will receive the same protection. Nor does a 1-in-500-year design standard mean flooding is impossible.
2. What the main parties are proposing for 2026
There are some meaningful differences in their approaches, but an important qualification: not every party has published a fully costed flood-protection funding policy.
The following comparison uses party representatives' public statements in August 2026, published election responses and existing government programmes. It distinguishes announced commitments from general policy direction.
Party positions as publicly documented by 30 October 2026. Not all positions are final election manifesto commitments.
National
National Party
Approach: practical infrastructure investment, national coordination and greater certainty.
National's government has:
- Established the National Adaptation Framework in 2025.
- Committed central government money to regional flood resilience projects.
- Supported a national flood mapping initiative.
- Proposed clearer responsibilities and adaptation planning for high-risk areas.
A particularly relevant existing funding example is the Regional Infrastructure Fund. In October 2025, the Government announced $96.8 million for 32 flood resilience projects, with central government covering 60% and local authorities the remaining 40%.

National's climate change minister Simon Watts also said in August 2026 that, if re-elected, National would develop national standards for river gravel extraction and on-farm quarrying to facilitate resilience work. Political parties make their climate adaptation pitchPolitical parties make their climate adaptation pitch
What it could mean for your family:
- More central government support for substantial flood infrastructure.
- Some protection against having the entire cost loaded onto local rates.
- Continued responsibility for councils and property owners.
- No established promise that your insurance will remain affordable or that every property will receive protection.
Labour
Labour Party
Approach: shared responsibility, including beneficiaries, the public and those contributing to climate risks.
Labour's climate spokesperson Deborah Russell outlined a particularly explicit funding philosophy at the August 2026 adaptation conference.
She identified four contributors:
- Beneficiaries of adaptation projects.
- Those who exacerbate climate change.
- The public, through central and local government.
- Banks and insurance companies, which Labour wants involved in helping communities prepare.
Labour also referred to earlier managed-retreat work and the parliamentary adaptation inquiry as important foundations for its thinking. Political parties make their climate adaptation pitch
However, Russell acknowledged that Labour's detailed election adaptation policy was still to come at that conference.
What it could mean for your family:
- Potentially more national-level funding rather than relying solely on local rates.
- More attention to insurance and financial institutions.
- A funding model that may still charge beneficiaries, including households in protected areas.
- Greater emphasis on deciding whether some particularly vulnerable places should eventually be relocated rather than continually defended.
The unanswered question is how much Labour would actually contribute to a Heretaunga Plains project, and how it would calculate the household contribution.
Green Party
Green Party
Approach: long-term climate adaptation, environmental resilience and equitable funding.
The Greens have argued for:
- More investment in green infrastructure and climate resilience.
- Stronger collaboration between central and local government.
- A national approach to adaptation that recognises Te Tiriti o Waitangi.
- Fairer distribution of adaptation costs, rather than placing the greatest burden on communities already exposed to climate risks.
At the August conference, co-leader Chlöe Swarbrick called for more integrated climate adaptation and mitigation policies and stronger relationships between central and local government. Political parties make their climate adaptation pitch2026 Election Q&A - Science
What it could mean for your family:
- Greater emphasis on long-term flood resilience rather than repeatedly rebuilding after disasters.
- Potentially more public funding for communities with substantial climate exposure.
- More consideration of natural flood management alongside engineering.
- Potentially more restrictions on development in areas identified as high-risk.
The key question to put to the Greens is whether their proposed fair funding model would include a specific central government contribution formula for existing communities such as Heretaunga.
ACT
ACT
Approach: property rights, practical engineering and caution about regulatory restrictions.
ACT's Simon Court argued in August that councils should consider practical alternatives before restricting people's use of property because of climate-risk scenarios.
He specifically identified:
- Upgrading stopbanks.
- Improving stormwater systems.
- Raising roads and houses.
- Coastal protection works.
ACT's position places particular emphasis on avoiding planning restrictions based on climate scenarios that it considers insufficiently certain. Political parties make their climate adaptation pitch
What it could mean for your family:
- Greater emphasis on engineering solutions that allow existing communities to remain in place.
- Less appetite for restrictions on property use based on projected hazards.
- Potentially more flexibility for homeowners.
- An important question about how much central government would pay for major infrastructure, rather than leaving councils and local ratepayers to finance it.
ACT had not provided a detailed flood cost-sharing formula in the public conference statements reviewed.
New Zealand First
New Zealand First
Approach: regional infrastructure and economic development.
NZ First has advocated:
- Practical regional infrastructure investment.
- Flood protection and water storage.
- Regional resilience funding.
- Applied environmental science.
Its election-related statements also emphasise economic development rather than making climate policy the dominant organising principle.
At the August adaptation conference, Shane Jones reiterated that economic growth should take priority in the party's political narrative. Political parties make their climate adaptation pitch2026 Election Q&A - Science
What it could mean for your family:
- Potential support for physical flood infrastructure.
- A focus on regional projects that protect productive land and communities.
- Less emphasis on climate-driven planning restrictions.
- Uncertainty about the long-term funding formula and how much homeowners would contribute.
The Opportunity Party
The Opportunity Party
Approach: a permanent national adaptation framework and shared responsibility.
Opportunity's representative Kayla Kingdon-Bebb proposed:
- A Climate Adaptation Act that could survive changes of government.
- Central government contributions when risks exceed local capacity or involve nationally significant assets.
- Continued local government investment.
- Some property-owner responsibility where risks are foreseeable.
- Transparent risk information from insurers.
This is one of the more explicit public descriptions of how the different contributors should share costs. Political parties make their climate adaptation pitch
What it could mean for your family:
- Greater consistency across successive governments.
- A stronger case for central government support for expensive regional projects.
- Continued contributions through rates and possibly individual property protection.
- Greater transparency about the long-term risks to your home.
Te Pāti Māori
Te Pāti Māori
The party has expressed support for equitable climate adaptation and emergency-response funding, with particular emphasis on climate justice, Māori authority and the interests of future generations.
Its election-related statements have also highlighted the importance of communities being able to participate in decisions affecting them. Election Survey 2026 - National Council of Women of New Zealand2026 Election Q&A - Science
What it could mean for your family:
- More emphasis on ensuring communities with limited financial capacity are not left carrying disproportionate costs.
- Greater consideration of marae, Māori land and affected whānau.
- A need for further detail about the specific funding arrangements for major flood infrastructure.
3. What is already funded in Hawke's Bay?
This is important because you should distinguish election promises from projects that already have funding.
There is already substantial central government investment in the region.
The Hawke's Bay cyclone recovery funding agreement
$203.5m
Central government contribution towards regional flood protection
The wider 2023 recovery agreement was worth up to $556 million.
- Approximately $100 million was earmarked for flood protection benefiting Hastings District.
- Projects include Pākōwhai, Ōmāhu, Waiohiki and Havelock North.
- The funding helped avoid substantially greater pressure on regional rates and the deferral or reduction of projects.
Cyclone Recovery Funding Hawke's Bay
Additional resilience funding
$256.5m
North Island Weather Event resilience programme
- $209 million from central government.
- $47.5 million from Hawke's Bay Regional Council.
- Seven major projects across the region.
There is also visible progress. The Ōhiti Road–Ōmāhu project reached its main construction completion milestone in August 2026, with 2.1 kilometres of new and upgraded stopbanks and associated drainage and road improvements. Ōmāhu flood project reaches the finish line | News Archive
These are real commitments, not simply campaign announcements.
However, future upgrades to the wider Heretaunga Plains scheme still require planning, engineering, funding and ongoing maintenance.
4. What happens to your rates and insurance?
This is where the policy differences become very tangible for your household.
Rates: how much might homeowners pay?
Hawke's Bay Regional Council's current funding arrangements allocate:
- 30% of flood scheme funding to the general rate.
- 70% to targeted rates based on capital value.
Drainage schemes have a different allocation, generally 10% general rates and 90% targeted rates. Hawke's Bay Regional Council Three-Year Plan 2024-2027
This means you can contribute through both the general rates system and targeted flood protection charges.
The political question is whether future large-scale improvements should continue to rely heavily on local ratepayers or whether central government should pay a greater proportion.
Consider two hypothetical funding arrangements for a $100 million project:
Chart
Illustrative funding scenarios, not actual party commitments or Hawke's Bay project budgets.
Expand chart
| Central government | Council and local rates | |
|---|---|---|
| 60/40 shared | $60m | $40m |
| 80/20 shared | $80m | $20m |
| Local-funded | $0m | $100m |
The difference is not just accounting. A greater central government contribution spreads the cost across taxpayers nationally, while a greater local contribution concentrates it on regional ratepayers.
Insurance: will better stopbanks mean cheaper insurance?
Not necessarily.
The Reserve Bank has documented an increasing move towards risk-based home insurance pricing. Insurers are increasingly assessing individual property exposure rather than simply treating all homes in a suburb alike.
The Reserve Bank's 2024 research found that some high-flood-risk properties were already attracting additional flood premiums. Insurance availability and risk-based pricing - Reserve Bank of New Zealand
The Treasury also recognises that increasing flood risk could affect whether some homes remain insurable. Residential insurance and climate-related hazards
For your family, this creates three important considerations:
- A publicly funded stopbank upgrade may reduce the physical risk to your home.
- An insurer may not immediately recognise the reduction in risk when calculating premiums.
- Even with better protection, residual risks can remain, including surface flooding, drainage failure and an event exceeding the design standard.
There is currently no general guarantee that public flood protection spending will translate into lower insurance premiums.
I would specifically ask your insurer whether completed local protection works will affect your property's risk assessment, and what evidence it requires.
5. The trade-offs for your family
The political differences become clearer when translated into the decisions you might face over the next 10–20 years.
| Issue | More central government funding | More local/property funding |
|---|---|---|
| Household rates | Potentially lower | Potentially higher |
| National taxes | Potentially higher | Less pressure from these projects |
| Infrastructure investment | Can spread major costs nationally | More dependent on local capacity |
| Local accountability | More shared responsibility | More direct local responsibility |
| Insurance | No automatic guarantee of lower premiums | No automatic guarantee either |
| Property decisions | Potential for nationally coordinated adaptation | Greater reliance on local decisions |
There are also some important longer-term trade-offs.
Protecting existing communities versus managed retreat
Some homes can be protected through engineering. Others may become increasingly difficult or expensive to defend.
A policy that prioritises stopbanks can help preserve your family's home, local schools, roads and community connections.
But it may involve substantial expenditure over generations, and it cannot eliminate all flood risk.
A managed-retreat approach may reduce exposure to future disasters, but raises difficult questions about compensation, replacement housing, mortgages, property values and whether families can afford to relocate.
Fairness between regions
If central government pays a greater share of Hawke's Bay flood protection, taxpayers elsewhere contribute too.
The argument for this is that major flood protection benefits regional economies, national food production, transport networks and wider economic activity.
The opposing concern is that national funding can become an open-ended commitment without sufficiently clear local accountability or cost controls.
Neither question is trivial.
6. Questions I would put to every party before voting
For a Heretaunga Plains homeowner, general statements about climate resilience are not enough.
I would look for specific answers to these six questions:
- Funding formula: What percentage of major regional flood protection projects will central government pay?
- Ratepayer protection: Will there be limits on how much local councils can charge affected households for nationally significant flood infrastructure?
- Insurance: Will the Government work with insurers to recognise the reduction in risk from completed public protection works?
- Residual risk: What happens to homeowners if a publicly funded stopbank fails or is overtopped?
- Relocation: If a home eventually becomes unsafe to occupy, what compensation and relocation assistance will be available?
- Delivery: Will existing Hawke's Bay projects be completed on schedule, and who pays if construction costs exceed their budgets?
That final question matters particularly because HBRC has identified that it bears the cost of project expenditure exceeding the allocated funding for the current resilience programme. Restoring Flood Resilience
7. Where to check the details before election day
These are useful primary sources rather than party campaign summaries:
- Hawke's Bay Regional Council – Resilient River Communities: local flood protection plans and projects.
- Hawke's Bay Regional Council: rates, annual plans and infrastructure funding.
- National Adaptation Framework: national policy and proposed adaptation legislation.
- Treasury – Residential insurance and climate-related hazards: insurance policy considerations.
- Electoral Commission: voting information. The general election is scheduled for 7 November 2026.
My overall assessment of the issues to weigh
I would separate the decision into three questions rather than trying to identify one party as the answer to every flood-related concern.
- Who pays for protection? Look at the actual central government versus local government funding formula, not just promises of infrastructure spending.
- Who protects your household financially? Look for specific insurance, residual-risk and buyout policies.
- Who makes decisions over the long term? Look at whether the party supports stable, multi-government planning that gives families and communities some certainty.
For a family with school-age children, the consequences extend beyond the value of your house. They include the security of remaining in your community, continuity of schooling, the affordability of insurance and rates, and whether your children can inherit a property that remains safe and financially viable.
One particularly important distinction: a party can support substantial flood infrastructure spending without necessarily supporting a national guarantee that homeowners will be compensated if their property becomes uninsurable or unsafe.
Those are separate policy commitments, and I would not assume one follows from the other.
My suggestion is to make the central-versus-local funding formula, insurance treatment and long-term homeowner protections your three main tests when examining the final party manifestos.
