# Question 120: We own a mortgaged home in an area affected by flooding. Insurance affordability, protection works and what happens after another flood are major concerns for us. I am considering my vote in the 2026 New Zealand general election. Who would pay for flood defences under different party plans: homeowners, councils or central government?

For a mortgaged home in a flood-prone area of New Zealand, the key question is not just who pays to build flood defences. It is also who pays to maintain them, who bears the cost if they fail, and whether your home remains insurable and affordable to own afterwards.

For the 2026 general election, it helps to separate three potential sources of funding:

- Homeowners: through rates, targeted rates, insurance premiums, excesses or direct contributions to protection works.
- Councils: through general rates, targeted rates, borrowing and local infrastructure budgets.
- Central government: through national taxes, grants, co-funding arrangements or nationally funded flood-protection programmes.

These sources can overlap. A government-funded grant, for example, might cover only part of a flood-defence project, leaving ratepayers to pay the balance.

## What the parties are proposing

As of 26 October 2026, parties have made some national adaptation commitments, but their policies are not equally detailed. The comparison below distinguishes announced positions from proposals that are still developing.

| Party | Who would pay for flood defences? | What this could mean for homeowners |
| --- | --- | --- |
| National | Central government has funded selected projects, while councils retain a major role. Its announced emphasis is on national adaptation planning and practical resilience works. [Flood resilience funding](https://www.growregions.govt.nz/new-funding/regional-infrastructure-fund/flood-resilience-funding)[Political parties make their climate adaptation pitch](https://www.odt.co.nz/news/national/political-parties-make-their-climate-adaptation-pitch-isw118ji) | National standards and better risk information could help planning, but the material reviewed does not establish a universal government guarantee to pay for defences around private homes. |
| Labour | A mix of beneficiaries, those who contribute to climate risk, central government and local government. Labour also wants banks and insurers involved. [Political parties make their climate adaptation pitch](https://www.odt.co.nz/news/national/political-parties-make-their-climate-adaptation-pitch-isw118ji) | Public funding could share costs, but homeowners who benefit from a particular scheme may still contribute. Labour's detailed election policy was still pending at the August policy discussion. |
| The Opportunity Party | A shared-responsibility model, with central government contributing when risks exceed local capacity or nationally significant assets are affected. Councils and property owners would also contribute. [Political parties make their climate adaptation pitch](https://www.odt.co.nz/news/national/political-parties-make-their-climate-adaptation-pitch-isw118ji)[Opportunity proposes national insurance support framework as part of climate policy](https://www.interest.co.nz/public-policy/140312/opportunity-wants-create-national-insurance-support-framework-identify-and) | Its September 2026 climate policy also proposes a national insurance-support framework, transparent risk assessments and fairer cost-sharing. This is a proposed framework, not a promise to cover every home's losses. |
| Green Party | Supports more green infrastructure and stronger central–local government cooperation. Its adaptation approach emphasises a coordinated, long-term response. [Political parties make their climate adaptation pitch](https://www.odt.co.nz/news/national/political-parties-make-their-climate-adaptation-pitch-isw118ji)[Manifesto 2026](https://www.greens.org.nz/manifesto_2026) | Could mean more emphasis on public coordination and nature-based protection, but the sources reviewed do not specify a universal household contribution formula for flood defences. |
| ACT | Its public position emphasises practical options, including upgrading stopbanks and stormwater systems, raising roads and houses, and considering alternatives to restrictive planning rules. [Political parties make their climate adaptation pitch](https://www.odt.co.nz/news/national/political-parties-make-their-climate-adaptation-pitch-isw118ji) | More emphasis on engineering solutions and property-level options; the statements reviewed do not specify a comprehensive national funding split. |
| New Zealand First | Its stated emphasis is economic development rather than making climate action a central political priority. The source reviewed does not set out a specific flood-defence funding formula. [Political parties make their climate adaptation pitch](https://www.odt.co.nz/news/national/political-parties-make-their-climate-adaptation-pitch-isw118ji) | There is less clarity in these statements about how the cost of future flood protection would be divided between homeowners and taxpayers. |

Important distinction: this is a comparison of positions documented in the sources, not a claim that every party has published a complete, final flood-protection policy. You can check the parties' current material directly through [National's 2026 policies](https://www.national.org.nz/policies?utm_source=chatgpt.com), [Labour's 2026 policies](https://www.labour.org.nz/policy?utm_source=chatgpt.com) and the [Green Party's 2026 manifesto](https://www.greens.org.nz/manifesto_2026?utm_source=chatgpt.com).

## What happens under the current system?

New Zealand already uses a mixed funding model, so the election question is how much each party would change that balance.

Homeowners and local ratepayers

Regional councils commonly use targeted rates on properties benefiting from a flood-protection scheme. Homeowners may also face general rates, higher insurance costs and the expense of protecting their own property. [Part 2: The flood protection system](https://ao.parliament.nz/2025/flood-protection/part2.htm)[Sector summaries: Flood protection | National Infrastructure Plan](https://tewaihanga.govt.nz/national-infrastructure-plan-online/sector-summaries/flood-protection)

Central government

The Government has funded specific resilience projects rather than guaranteeing to pay for every local defence. For example, the Regional Infrastructure Fund provided $101.1 million for 42 flood-resilience projects in 2024, followed by another $96.8 million for 32 projects in 2025. [Flood resilience funding](https://www.growregions.govt.nz/new-funding/regional-infrastructure-fund/flood-resilience-funding)

After another flood

Insurance may cover damage according to your policy, exclusions and excess. If insurance becomes unavailable or unaffordable, homeowners can face much greater financial exposure. There is no general guarantee that the Government will compensate every homeowner for future flood losses. [Residential insurance and climate-related hazards](https://www.treasury.govt.nz/news-and-events/reviews-consultation/residential-insurance-and-climate-related-hazards)[Adaptation options including managed retreat](https://environment.govt.nz/publications/aotearoa-new-zealands-first-national-adaptation-plan/adaptation-options-including-managed-retreat/)

The Office of the Auditor-General also notes that councils may need to upgrade defences just to maintain their existing level of protection as flood risk changes. A defence is not a guarantee against all future floods. [Part 2: The flood protection system](https://ao.parliament.nz/2025/flood-protection/part2.htm)

## What matters most for your mortgage?

For your situation, I would examine four specific commitments in each party's detailed policy.

- Upfront funding: Would central government pay a defined share of the cost of new or upgraded flood defences, rather than leaving councils to raise targeted rates?
- Ongoing maintenance: Who would fund repairs and future upgrades, and could those costs produce substantial increases in your rates?
- Insurance affordability: Would there be support for households facing unaffordable premiums or losing access to flood insurance?
- What happens if protection is no longer viable: Would the policy provide a clear process and funding for voluntary property buyouts or managed retreat, and how would outstanding mortgages be handled?

That last question is especially important. A buyout or relocation scheme is different from flood insurance, and neither should be assumed to repay a mortgage in full without explicit terms.

For the voting decision, the clearest distinction is between parties offering defined national cost-sharing commitments and parties relying more on local funding, practical works or a future national framework. The announcements reviewed do not establish a complete, binding funding formula for every party, so the detail of any final policy matters.

For homeowners in flood-prone areas, the question of who pays for flood defences, managed retreat, and infrastructure protection is a major point of difference among political parties in the 2026 New Zealand general election. 

Under New Zealand's current framework, the costs are traditionally split between **homeowners** (via insurance and property rates), **local councils** (via local rates and debt), and **central government** (via ad-hoc disaster recovery funds and national infrastructure support). However, the major political parties approach the funding burden, risk mitigation, and post-flood support differently:

---

### 1. National & NZ First (Coalition Government Approach)
* **Central Government vs. Councils/Homeowners:** This approach leans toward fiscal conservatism, emphasizing targeted regional co-investment rather than broad, open-ended central bailouts. While the government has backed regional infrastructure initiatives (such as through the Regional Infrastructure Fund targeting flood protection and water storage) and rolled out national risk mapping (like the New Zealand Flood Map), it has also rolled back parts of central climate adaptation funding pools.
* **Impact on Councils & Homeowners:** A greater share of the ongoing cost for local protective works tends to fall back on local authorities and regional co-investments. For councils with tight debt caps, this often translates to higher targeted rates for property owners in flood-prone zones, while property-level defences or insurability remain largely private responsibilities.

### 2. Labour Party
* **Central Government Involvement:** Labour emphasizes a stronger central government role, arguing that extreme weather demands heavy national infrastructure funding and structured national frameworks for climate adaptation and managed retreat. 
* **Impact on Councils & Homeowners:** Labour’s historical framework and policy positions aim to co-share costs centrally to protect smaller or under-resourced council districts. The objective is to shield vulnerable communities and local ratepayers from extreme rate hikes and prevent sudden mortgage defaults by using national funds to anchor large-scale flood builds and community protection.

### 3. Green Party
* **Central Government Leadership:** The Greens advocate for the largest central government intervention on climate adaptation. They criticize reductions in baseline climate resilience spending and push for massive increases in central climate funds.
* **Impact on Councils & Homeowners:** Their framework aims to minimize out-of-pocket costs for low-to-middle-income homeowners and heavily support local authorities. The Greens propose that central government grants and dedicated climate funds should heavily absorb the costs of community-wide protection barriers and managed retreat programs, rather than leaving private property owners or stretched local councils to bear the burden.

### 4. ACT New Zealand
* **Market-Led & Risk-Reflective Approach:** ACT generally opposes large-scale, blanket government subsidies for climate adaptation that spread costs across all taxpayers, arguing instead that policies should focus on economic efficiency and property rights.
* **Impact on Councils & Homeowners:** ACT's framework places a heavier emphasis on variable rates that directly reflect individual property flood risk. Under this approach, homeowners in high-risk zones face costs that more accurately mirror their actual exposure, encouraging private risk assessment, individual property-level adaptation, and insurance clarity rather than broad public subsidisation.

---

### Summary for Your Vote
* If you favor **central government intervention** to shoulder the financial burden of flood defences and protect local ratepayers, centre-left parties (**Labour, Greens**) offer policies focused on central funding pools and co-sharing.
* If you favor **fiscal restraint, regional co-investment, or risk-reflective costs** where local areas or individual risk profiles manage the expense, centre-to-right parties (**National, ACT, NZ First**) lean more toward local council responsibility, targeted co-funding, and avoiding broad central underwriting.

As _New Zealand_ navigates increasing severe weather events, the question of **who pays for climate adaptation and flood defences** is a central point of debate for the 2026 general election. Currently, funding responsibility is traditionally split between local councils (via rates) and central government (via ad-hoc disaster response or regional funds), leaving a heavy burden on local communities and individual homeowners.

The major political parties diverge significantly on how the cost burden should be shared between central government, local councils, banks/insurers, and property owners:

 * * _National Party / Coalition Government:_ Focuses on a **practical planning and risk-reduction framework** (the National Adaptation Framework) alongside a streamlined resource management system and a national flood-mapping initiative. Their approach relies heavily on localized planning by councils with targeted central support (such as regional infrastructure allocations) rather than an open-ended central underwriting of all local flood defense works. They place greater emphasis on practical engineering (like river gravel extraction) and avoiding mandates that force extreme-risk decisions prematurely.

 * _Labour Party:_ Advocates for a **mixed funding model** that distributes costs across beneficiaries, exacerbators (those contributing to or building in high-risk zones), public funds, as well as financial institutions like banks and insurance companies. Labour critiques current central funding levels as insufficient and envisions a more interventionist central government framework sharing the financial load alongside the private finance sector.

 * _Green Party:_ Emphasizes **increased central government investment** and criticizes current and recent government allocations for scaling back direct central spending on flood protection. The Greens favor robust public funding integrated with green infrastructure, arguing that central government must step up substantially to support communities rather than leaving councils and ratepayers exposed to escalating climate costs.

 * _The Opportunities Party (TOP):_ Proposes a dedicated **$5 billion climate resilience fund** funded by central government for prevention and resilience works. They also propose a national insurance support framework and risk disclosure regime, shifting more proactive capital and coordination responsibilities onto the central government to prevent repetitive disaster recovery payouts.

 * _ACT New Zealand:_ Skeptical of heavy-handed central mandates or councils utilizing extreme climate worst-case scenarios to prematurely devalue or restrict properties. They emphasize cost-effective, practical local engineering solutions and caution against ballooning central government spending and bureaucracy. [RNZ]

 * _New Zealand First:_ Prioritizes economic growth and cost-of-living relief over climate-specific adaptation funding, generally opposing large-scale climate taxes or international frameworks in favour of conventional economic priorities. [RNZ]

For homeowners in flood-prone areas, the **2026 General Election** presents distinctly different approaches to funding flood defenses and handling climate adaptation. Because major insurance companies are increasingly shifting to granular, property-by-property flood risk pricing, your future premiums and mortgage compliance heavily depend on who pays for protective infrastructure or a potential "managed retreat".

Here is how the main political parties propose allocating the costs among **central government, local councils, and homeowners** :

🏛️ The National-Led Government Approach

The **National Party** , governing alongside **ACT** , focuses on clear cost-sharing frameworks, deregulation, and targeted infrastructure funds rather than massive central government pools.

 * **Central Government:** National implemented the **National Adaptation Framework** , establishing a clear cost-sharing blueprint between the Crown and councils. Rather than broad central funding, they replaced previous climate funds with the **Regional Infrastructure Fund (RIF)** , which contributes co-funding for regional flood defenses.

 * **Councils:** Local councils bear the primary responsibility for planning and building hard defenses (like stopbanks) using local rates, but they gain greater authority to mandate local adaptation plans.

 * **Homeowners:** Homeowners face a system that relies on market transparency. National is rolling out a **National Flood Map** (targeted for 2027) so insurers and buyers can see exact risks. If protection works are not built, homeowners absorb the cost of rising insurance premiums or property devaluation.

 * **ACT Party Plan:** ACT strongly favors prioritizing practical on-the-ground adaptation over emission mitigation. They support **deregulation** to allow councils and communities to build drainage and raise roads faster and cheaper. However, they strictly oppose large central crown subsidies for localized retreats, meaning homeowners in high-risk zones carry more individual risk.

🌹 The Labour Party Plan

The **Labour Party** advocates for heavier central government intervention to shield households from financial ruin, though they advocate for a bipartisan, long-term approach to take the "politics out of infrastructure".

 * **Central Government:** Labour heavily criticizes the current government’s cuts to the Climate Emergency Response Fund. If elected, they lean toward using central government borrowing to fund extensive climate resilience. They support central Crown interventions to provide a safety net for high-risk areas.

 * **Councils:** Labour envisions central government working in tandem with councils to fund massive remediation or managed retreats. They acknowledge that small or underfunded regional councils cannot afford multi-billion dollar defenses on their own.

 * **Homeowners:** Homeowners would receive higher levels of state-backed financial protection. Under Labour's philosophy, central intervention aims to prevent homeowners from being completely "stranded" by private insurers fleeing high-risk flood zones.

🌿 The Green Party Plan

The **Green Party** proposes the most aggressive, centrally-funded framework targeted at community and nature-based defenses.

 * **Central Government:** The Greens propose substantial, ring-fenced central funds—such as their previously championed **$750 million Climate Resilient Towns fund** —to build natural flood buffers.

 * **Councils:** Councils would receive massive, direct cash injections from the central government specifically to implement nature-based flood mitigation (like wetlands, green spaces, and river restoration) rather than relying strictly on concrete infrastructure or hiking local rates.

 * **Homeowners:** Homeowners would benefit from state-funded community protection. For properties that simply cannot be saved, the Greens support a robust, centrally-funded **managed retreat scheme** to offer fair compensation, reducing the likelihood that a homeowner is left holding a worthless, uninsurable mortgage.

🪙 New Zealand First Plan

 * **Central Government & Regions:** NZ First focuses heavily on regional funding. They advocate for schemes like the **Regional Infrastructure Fund** and returning **50% of mining royalties** back to the regions. This money is explicitly earmarked for local infrastructure, allowing provincial councils to build and maintain robust flood protections without over-burdening local residential ratepayers.

* * *

Summary Comparison

Party| Primary Funding Source| Impact on the Homeowner
---|---|---
**National / ACT**| **Co-shared** (RIF Central funds + Council rates)| **Higher Market Exposure** : Relies on risk transparency maps. Homeowners rely on market insurance pricing.
**Labour**| **Central Government** (Heavier Crown funding & borrowing)| **Higher Protection** : State intervention aims to shield homeowners from being financially stranded.
**Greens**| **Central Government** (Large dedicated climate trusts)| **Community & Eco-focused**: Heavy emphasis on state-funded eco-buffers and structured retreat compensation.
**NZ First**| **Regional/Resource Taxes** (Royalties returned to regions)| **Provincial Protection** : Focuses on protecting regional property values via localized infrastructure funds.
