Every question, every answer, every source

For a homeowner with a flood-affected, mortgaged property, the key election questions are likely to be:

• Will government help keep homes insurable?
• Who pays for flood protection and adaptation works?
• What happens if a home becomes unsafe or effectively uninsurable?
• Will there be buyouts, compensation, or only planning restrictions?

New Zealand parties have not all published equally detailed policies specifically for “the homeowner whose house can no longer be insured”, so the comparison below focuses on their stated positions on climate adaptation, flood risk, insurance, infrastructure, and housing risk. The issue is becoming more prominent because the government has acknowledged that climate change may challenge the insurability of some homes and is considering the future role of insurance in adaptation.

National Party (current government)

General approach: risk reduction, adaptation planning, and infrastructure investment.

National’s emphasis has been on practical adaptation: improving resilience, planning ahead, and giving communities more certainty about future risks. Its climate adaptation messaging has focused on reducing risk through investment and clearer responsibilities. Otago Daily Times

For a flood-prone homeowner, this suggests:

• More focus on flood protection works, infrastructure upgrades, and risk information.
• A preference for managed adaptation rather than broad government guarantees for every at-risk property.
• The difficult question of who pays when protection is uneconomic remains central.

The government’s National Adaptation Framework includes ideas around risk information, roles and responsibilities, investment in risk reduction, and cost-sharing before and after events. Ministry for the Environment

Questions to ask National candidates:

• Will there be a national framework for homes that become uninsurable?
• Will homeowners receive financial help for relocation, raising floors, or flood resilience work?
• How will mortgage holders be protected if insurers withdraw cover?

Labour Party

General approach: stronger government role in climate resilience and public protection.

Labour has generally supported a more active government role in climate adaptation and public investment. A homeowner considering Labour would likely want to examine whether its proposed approach includes:

• stronger central government funding for flood protection;
• clearer rules around councils’ responsibilities;
• assistance for communities facing managed retreat.

The key issue is whether Labour proposes a specific mechanism for individual homeowners facing loss of insurance or loss of property value, rather than broader infrastructure spending.

Green Party

General approach: stronger climate action, adaptation, and public intervention.

The Greens have generally argued for stronger climate policy and greater government involvement in responding to climate risks. Their climate adaptation position is likely to appeal to voters prioritising:

• faster emissions reduction;
• stronger planning controls in high-risk areas;
• greater public investment in resilience.

A homeowner should look specifically for details on:

• whether the party supports government-funded buyouts or relocation assistance;
• how it would handle existing homeowners who bought before risks were fully understood;
• how costs would be shared between taxpayers, councils, insurers, and property owners.

ACT Party

General approach: smaller government, individual responsibility, and market mechanisms.

ACT’s broader philosophy emphasises limited government, lower regulation, and individual choice. PartyMap

For flood-affected homeowners, this could mean:

• preference for targeted rather than universal government assistance;
• emphasis on removing barriers to development and infrastructure delivery;
• more reliance on insurance markets and property owners managing risk.

Questions to ask:

• Does ACT support any government role when insurance markets fail?
• Should taxpayers help protect or relocate privately owned homes?
• How should councils deal with properties that are technically legal but becoming uninsurable?

---

New Zealand First

General approach: community protection and infrastructure, with emphasis on practical outcomes.

NZ First has often focused on regional infrastructure and protecting communities. The relevant questions are:

• Does it support central government funding for flood protection?
• Does it support relocation or buyout schemes?
• How would it balance protecting existing communities with avoiding repeated rebuilding in high-risk areas?

The biggest unresolved issue: “managed retreat” and uninsurable homes

Across New Zealand, the hardest policy question is not just building stopbanks or repairing roads. It is what happens when:

• a house is still standing but insurers will not cover it;
• a bank will not lend against it;
• the council restricts rebuilding;
• the owner still owes a mortgage.

The options governments generally consider are:

1. Protect

   • Fund floodwalls, drainage, river works, coastal protection, or raising buildings.

2. Adapt

   • Fund resilience measures such as flood-proofing and building changes.

3. Relocate

   • Buyouts, voluntary retreat, or compensation schemes.

4. Leave it largely to owners and markets

   • Higher premiums, reduced cover, or private decisions.

The major party differences are likely to be about how much government should intervene and who should pay.

A useful way to compare parties before voting

For your situation, I would look for each party’s answer to these five questions:

1. If my insurer leaves, who helps me?
2. If my home is unsafe after a flood, what happens to my mortgage?
3. Will government fund protection works, and for how long?
4. Will there be a fair buyout/relocation process?
5. Will councils be forced to disclose future flood risk before homes are bought and sold?

You may also find it useful to compare the parties’ published 2026 policy positions through election policy comparison sites such as Policy.nz, which collates party policies by topic. Policy.nz

Because election manifestos can change during the campaign, the most important thing to watch is whether a party moves from general “adaptation” language to a concrete promise about insurance withdrawal, mortgages, and homeowner compensation.
