# 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 your situation — a mortgaged home in a flood-affected area, with rising insurance costs and uncertainty about what happens after another flood — the key election question is who carries the cost of reducing the risk before the next flood, and who pays if protection is no longer practical?

In New Zealand, the existing system generally puts regional councils in charge of major flood-protection schemes, territorial councils in charge of local stormwater and land-use planning, and homeowners in charge of some drainage and private protection. Councils often recover costs through rates, while central government can co-fund projects. [Sector summaries: Flood protection | National Infrastructure Plan](https://tewaihanga.govt.nz/national-infrastructure-plan-online/sector-summaries/flood-protection)[Government Response to the National Infrastructure Plan 2026](https://www.beehive.govt.nz/sites/default/files/2026-06/Government%20Response%20to%20the%20National%20Infrastructure%20Plan.pdf)

That means the cost can reach homeowners even when a council or the Government organises the work. The important distinction between party policies is whether they would keep that local funding model, increase central-government contributions, or create a national system for sharing the costs of flooding and retreat from high-risk areas.

## How the main party approaches compare

The following reflects published positions available as of 22 October 2026, ahead of the 7 November general election. A proposal to share adaptation costs is not the same as a commitment to pay for a particular stopbank or guarantee compensation after a flood.

### National

Central government + councils + property owners

National's approach emphasises consistent flood-risk information, planning ahead, and practical adaptation. Its Government has partnered with local government on $197.9 million of Regional Infrastructure Fund projects, including flood resilience works. In August, its climate-adaptation position was described as central government contributing when risks exceed local capacity or affect nationally significant assets, with local government continuing to invest and property owners bearing some responsibility where risks are foreseeable. [Government Response to the National Infrastructure Plan 2026](https://www.beehive.govt.nz/sites/default/files/2026-06/Government%20Response%20to%20the%20National%20Infrastructure%20Plan.pdf)[Political parties make their climate adaptation pitch](https://www.odt.co.nz/news/national/political-parties-make-their-climate-adaptation-pitch-isw118ji)[Funding to boost resilient planning system](https://www.national.org.nz/news/funding-to-boost-resilient-planning-system)

For homeowners: Public co-funding is possible, but I found no general promise that the Crown would pay the full cost of protecting your property or compensate every homeowner after another flood.

### Green Party

Greater emphasis on public climate action and resilience

The Greens' 2026 manifesto commits to preparing New Zealanders for climate impacts, including increasingly severe storms and floods. The party has also criticised the current Government's flood-protection spending, arguing for stronger investment. [Manifesto 2026](https://www.greens.org.nz/manifesto_2026)[Luxon's Government cut flood protection spending while extreme weather worsens](https://www.greens.org.nz/_luxon_s_government_cut_flood_protection_spending_while_extreme_weather_worsens)

For homeowners: The party's published material supports stronger climate resilience, but the sources I checked did not establish a complete, specific formula allocating the cost of each flood defence among central government, councils and individual homeowners.

### Labour

A proposed mix of funding sources

Labour's climate-adaptation approach has been reported as involving a mix of beneficiary-pays and exacerbator-pays principles, central and local government funding, and involvement from banks and insurers. A fuller policy was still to be announced in the comparison material I found. [Compare Parties — NZ 2026 Election](https://nzelectionhub.com/compare)[Political parties make their climate adaptation pitch](https://www.odt.co.nz/news/national/political-parties-make-their-climate-adaptation-pitch-isw118ji)

For homeowners: The proposed approach would spread responsibility across several parties, rather than relying exclusively on council rates. The precise homeowner contribution, funding thresholds and compensation rules remain important details to verify.

### Opportunity Party

Explicit national framework for insurance retreat and shared costs

Opportunity's September 2026 climate policy proposes a National Insurance Support Framework, with forward-looking risk assessments for homeowners, national rules for managing insurance retreat, and cost-sharing among central government, local government, insurers and property owners. It also proposes an expanded role for the Natural Hazards Commission. [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)[Opportunity Party proposes new rules for insurance retreat](https://www.insurancebusinessmag.com/nz/news/catastrophe/opportunity-party-proposes-new-rules-for-insurance-retreat-590281.aspx)

For homeowners: This is an explicit proposal to establish rules for sharing costs when properties become difficult to insure. However, the exact shares and eligibility criteria have not been settled, and it is not a guarantee that the Government will pay off a mortgage or replace a flood-damaged home.

For ACT and New Zealand First, the material retrieved did not establish a sufficiently detailed, directly comparable national flood-defence cost-sharing commitment. That is not proof they have no relevant policies; it means I would not confidently assign them a homeowner, council or Crown funding split based on the available evidence. National's current planning approach and the broader policy discussion are documented in the sources above.

## What happens if your home floods again?

This is where flood-defence funding and household financial protection need to be considered separately.

| Issue | Who may pay under the current system? |
| --- | --- |
| Major stopbanks and river protection | Regional council, often funded through rates; central government may co-fund |
| Local stormwater upgrades | Usually territorial council, with costs recovered through rates and other funding |
| Drainage and small private defences | Often the property owner |
| Damage to your home | Your insurer, if the damage is covered and policy conditions are met; otherwise you may bear some or all of the loss |
| A home that becomes difficult to insure | Depends on insurance terms, the Natural Hazards Commission's statutory cover, and any applicable government or council support |
| Relocation or managed retreat | Depends on the specific scheme and decisions made; there is no universal guarantee of full compensation |

These are general arrangements, not a determination of your property's legal entitlements. Flood insurance and adaptation are ongoing policy issues for the Government. [Sector summaries: Flood protection | National Infrastructure Plan](https://tewaihanga.govt.nz/national-infrastructure-plan-online/sector-summaries/flood-protection)[Residential insurance and climate-related hazards](https://www.treasury.govt.nz/news-and-events/reviews-consultation/residential-insurance-and-climate-related-hazards)[Government Response to the National Infrastructure Plan 2026](https://www.beehive.govt.nz/sites/default/files/2026-06/Government%20Response%20to%20the%20National%20Infrastructure%20Plan.pdf)

## Four questions worth asking before you vote

For a mortgaged household, the headline amount spent on flood protection is only part of the story. Ask each party:

- Who pays for the defence? Will central government cover a defined share of major works, or will the cost largely fall on local ratepayers?
- Who pays if the defence fails? Is there any proposed financial support beyond existing insurance and statutory entitlements?
- What happens if insurance becomes unaffordable? Would there be a national support scheme, help with premiums, or a funded relocation option?
- What happens to the mortgage? Would any retreat or compensation scheme address outstanding mortgage debt, or would homeowners still be liable for the shortfall?

That final question is particularly important: a policy can offer relocation assistance without guaranteeing that a household can clear its mortgage.

The central distinction to keep in mind: paying for flood defences is not the same as paying to protect a homeowner from financial ruin after a flood. Compare parties on both commitments, and look for actual funding amounts, eligibility rules and mortgage treatment rather than broad promises of resilience.

For homeowners with a mortgaged property in a flood-prone area, the question of who pays for climate adaptation, flood defences, and post-disaster recovery is a central economic and political issue. 

While specific party policy manifestos for the **2026 New Zealand General Election** heavily emphasize different funding philosophies, the debate fundamentally centers on how the financial burden should be shared between **central government, local councils (ratepayers), and private property owners (homeowners/insurance)**. 

---

### 1. Central Government Funding (The Crown)
* **What it looks like:** Direct fiscal investment from national tax revenue, co-funding arrangements, and specific funds (such as the Regional Infrastructure Fund or post-disaster packages like the 2023 flood/cyclone buy-out co-funding schemes).
* **Party Philosophy:** 
  * **National / Centre-Right Parties:** Generally favor targeted, infrastructure-led support (e.g., co-investing in regional flood resilience projects and infrastructure via tools like the Regional Infrastructure Fund), while emphasizing fiscal discipline. They are typically cautious about open-ended, nationwide Crown bailouts for private property, preferring to establish clear national adaptation frameworks that define the limits of central government liability.
  * **Labour / Centre-Left Parties:** Tend to advocate for a stronger, more proactive central government role in climate adaptation, arguing that local councils and individual ratepayers cannot shoulder the immense capital costs of major flood defences alone. They emphasize equity, systemic risk reduction, and greater Crown partnership in funding community-level resilience and managed retreat where necessary.
  * **Green / Te Pāti Māori:** Strongly push for systemic climate action, viewing adaptation and flood defence funding as an urgent public good responsibility. They advocate for nature-based solutions (like wetland restoration and reforestation) backed by substantial state funding, alongside targeted support for vulnerable communities.

### 2. Local Councils (Ratepayers)
* **What it looks like:** Funding via regional and district council rates (general rates or targeted rates levied specifically on properties benefiting from a flood scheme) and council borrowing (debt).
* **The Reality & Debate:** Historically, regional councils have managed flood protection schemes, funded largely by local ratepayers. However, major reports (including from the Office of the Auditor-General and local government sector groups like Te Uru Kahika) highlight that many councils face severe financial constraints and escalating debt caps. 
* **The Party Split:** 
  * Right-of-centre parties often emphasize fiscal restraint for local authorities, pushing them to prioritize core infrastructure within existing revenue limits or use public-private partnerships.
  * Left-of-centre and minor parties argue that relying heavily on local council rates creates a "postcode lottery," where wealthier councils can afford robust flood defences while lower-income regions are left exposed, necessitating heavier central government subsidisation.

### 3. Homeowners and the Insurance Market
* **What it looks like:** Privately funded property-level mitigations (raising homes, installing flood barriers), rising property insurance premiums, higher insurance excesses, or the risk of becoming uninsurable.
* **The Current Crisis:** The Insurance Council of New Zealand (ICNZ) has sharply pressed the government to resolve the national adaptation funding framework, warning that without publicly funded regional protection works or clear managed-retreat pathways, insurers will increasingly price properties based on raw hazard data—leading to skyrocketing premiums, restricted coverage, or withdrawal from flood-prone areas altogether.
* **Party Approaches:** 
  * Mainstream parties are wrestling with how to prevent the insurance gap from widening, but generally agree that private homeowners cannot be left entirely on their own to build multi-million-dollar community flood walls. 
  * Debates continue on whether property owners in high-risk zones should face higher individual costs (to discourage building in harm's way) versus receiving government-backed safety nets to protect existing generational investments.

### Summary Checklist for Your Vote
When evaluating party manifestos ahead of the election, look closely at their stances on:
1. **Co-funding formulas:** Are they committing ongoing, predictable Crown funding to match council spending for regional flood protection infrastructure, or expecting regions to self-fund?
2. **Managed retreat and buy-outs:** If a property faces intolerable risk, is there a clear, nationally funded framework for property buy-outs, or is the financial loss left to the homeowner and their mortgage lender?
3. **Insurance stability:** What are their proposals for addressing insurance affordability and the growing vulnerability of homes in low-lying or river-adjacent zones?

Currently, no single party has locked in a final, standalone statutory funding blueprint, but distinct philosophies and approaches have emerged from the major political blocs regarding whether the burden should fall on central government, local councils, or property owners/beneficiaries.

1\. The National-led Government (Current Administration)

 * * **Core Philosophy:** Favors a **"beneficiary pays"** and **co-funding** model, leaning heavily on recommendations from its independent advisory groups rather than open-ended central government underwriting. [www.farmersweekly.co.nz]

 * **Who pays under their approach?**
 * **Central Government:** Provides targeted regional infrastructure funding (such as $200 million via the Regional Infrastructure Fund for flood resilience projects) and is proposing mandatory long-term climate adaptation plans for councils. However, the current government has kept central spending lower relative to previous labor allocations, arguing that central government cannot shoulder the entire bill.
 * **Councils & Homeowners ("Beneficiary Pays"):** The administration's independent reference group framework suggests that those who directly benefit from local protection works or choose to remain in high-risk zones should primarily fund those measures. This leaves local councils struggling with local balance sheets, often resulting in local rates increases or user-pays mechanisms.

 *

2\. The Labour Party

 * * **Core Philosophy:** Advocates for a **hybrid "shared responsibility" model** combining public funding, polluter/exacerbator accountability, and close coordination with the banking and insurance sectors. [RNZ]

 * **Who pays under their approach?**
 * **Central & Local Government (The Public):** Labour argues for a substantial public sector role (both central and local) to build resilience and handle adaptation frameworks, criticizing the current government for scaling back dedicated flood-resilience budgets.
 * **Exacerbators & Beneficiaries:** They propose a mix where "exacerbators" (those who contribute heavily to emissions/climate change) and direct beneficiaries share the costs.
 * **Private Sector:** Labour aims to actively partner with commercial banks and insurance companies to structure risk-mitigation finance, rather than leaving homeowners entirely to market forces.

 *

3\. The Green Party

 * * **Core Philosophy:** Strongly advocates for **heavy central government investment** and urgent public funding, framing climate adaptation as a national crisis requiring direct state intervention. [Green Party of Aotearoa New Zealand]

 * **Who pays under their approach?**
 * **Central Government:** The Greens argue that the central government must significantly scale up direct funding for community resilience and flood protection—criticizing current government spending levels as a major cut compared to previous allocations. They push for large-scale central appropriations rather than pushing costs down to local ratepayers or vulnerable individual homeowners. [Green Party of Aotearoa New Zealand]

Summary Comparison of Who Pays

Party Approach| Central Government Role| Local Council / Ratepayer Role| Homeowner / Beneficiary Impact
---|---|---|---
**National-led**| Targeted co-funding ($200M regional pool); framework setting.| High pressure; expected to manage local risk on local balance sheets.| High adherence to **"beneficiary pays"** ; localized costs or managed retreat decisions fall close to home.
**Labour**| Active public investment paired with banking/insurance frameworks.| Shared public responsibility alongside central government.| Hybrid model splitting costs between public funds, "exacerbators," and beneficiaries.
**Greens**| Substantial increase in direct central government spending for climate resilience.| Relieved of the solo financial burden via massive state-backed funding.| Lower direct localized financial burden for infrastructure; emphasis on state-led protection.

The 2026 general election highlights a major policy split regarding who pays for flood defenses, managed retreat, and infrastructure resilience. For a homeowner in a flood-affected area, the cost-sharing framework between **homeowners, councils, and the central government** varies significantly by party.

The core debate centers around whether funding should follow a **"beneficiary pays"** framework (shifting costs toward homeowners and developers) or a **shared public infrastructure** framework (funded primarily by councils and the central government).

* * *

**National Party & ACT (Governing Coalition)**

The current government emphasizes fiscal discipline, localized infrastructure financing, and practical engineering over central government buyouts.

 * **Who Pays:** Primarily **homeowners (beneficiaries) and councils** , with targeted central government co-funding for critical regional work.

 * **The Plan:**
 * **Beneficiary Pays Principle:** Prime Minister _Christopher Luxon_ has signaled that the central government cannot keep bailing people out indefinitely. The government leans toward a framework where adaptation measures (like sea walls and flood schemes) are funded by the specific communities that benefit from them.
 * **Levy-Funded Infrastructure:** Under the Infrastructure Funding and Financing (IFF) Act championed by the coalition, special-purpose vehicles can fund flood protection infrastructure off council balance sheets. This infrastructure is then paid for via **targeted levies on the homeowners** who directly benefit.
 * **ACT's Position:** ACT cautions against using extreme global-warming scenarios to make property decisions and advocates for practical, localized engineering interventions rather than costly government-managed retreat.

**Labour Party**

Labour opposes putting the entire financial burden on individual homeowners and favors a broad, collaborative risk-sharing model.

 * **Who Pays:** A **mixed funding model** shared dynamically between **homeowners, councils, the central government, banks, and insurers**.

 * **The Plan:**
 * **Shared Responsibility:** Labour argues that "who pays" cannot be a single entity. They plan to utilize the recommendations from previous parliamentary inquiries to build a framework where financial risks are distributed across the public sector, individual property owners, and the financial institutions (banks/insurers) holding mortgages on those properties.
 * **National Resilience Fund:** Labour previously introduced a $6 billion National Resilience Fund to address infrastructure repair and protection following Cyclone Gabrielle. While the fund was canceled by the current government, Labour advocates for structural, long-term central funding for adaptation.

**Green Party**

The Greens advocate for a comprehensive, highly structured legislative approach with significant central government involvement.

 * **Who Pays:** Primarily the **central government and councils** , financed by shifting the tax burden to large polluters and capital.

 * **The Plan:**
 * **Climate Adaptation Framework:** The Greens heavily criticize the current government for delaying cost-sharing decisions and putting "unfunded mandates" onto local councils. They want a legislated, cross-party framework that details exact funding allocations so homeowners are not left guessing who pays.
 * **Publicly Funded Protection:** The Greens emphasize public investment in "blue-green infrastructure" (nature-based flood management) and community-led adaptation rather than relying on private homeowners to fund individual defenses.

**New Zealand First**

 * **Who Pays:** Primarily **councils and regional funds** via dedicated infrastructure grants.

 * **The Plan:** NZ First approaches the issue through the lens of regional productivity rather than explicit climate policy. They utilize their **$1.2 billion Regional Infrastructure Fund** to directly target flood protection and water storage in regional New Zealand, aiming to reduce the immediate capital burden on local councils and ratepayers.

**The Opportunity Party (TOP)**

 * **Who Pays:** A **structured, transparent split** outlined by new national rules.

 * **The Plan:** TOP proposes a multi-party Climate Adaptation Act to establish precise national guidelines for insurance retreat. Their framework sets clear rules specifying exactly when a property becomes uninsurable, who bears the cost, and what compensation or defence funding homeowners are legally entitled to.

* * *

**Summary Comparison**

Party| Primary Funding Source| Impact on Flood-Zone Homeowners
---|---|---
**National / ACT**| **Homeowners & Councils** (via IFF levies)| Higher likelihood of targeted rates/levies to pay for local defenses; less central government buyout support.
**Labour**| **Shared Cost** (Govt, Councils, Banks, Insurers, Owners)| Shared financial burden, potential legislative support involving the banking and insurance sectors.
**Greens**| **Central Government & Councils**| Highly subsidized public defense and managed retreat infrastructure, funded through broader tax reforms.
**NZ First**| **Regional Infrastructure Fund**| Capital injection into physical flood schemes, particularly prioritizing regional areas.
