For the 2026 New Zealand general election: How do parties compare on emissions reduction, climate adaptation and the cost of disaster protection?
As of 4 October 2026, the major parties are quite far apart on climate policy. The election is scheduled for 7 November 2026. 2026 Election Q&A - Science - Science Media Centre
A useful way to compare them is to separate mitigation (cutting emissions), adaptation (protecting people and infrastructure from floods, storms, drought and sea-level rise), and who ultimately pays.
| Party | Emissions reduction | Climate adaptation | Who pays / cost of protection |
|---|---|---|---|
| National | Keep the 2050 net-zero commitment, but emphasise technology, economic growth and a relatively moderate ETS approach. It is backing gas as an energy-security measure and methane-reduction technology. Budget 2024 supports practical climate action | National Party | National has established a National Adaptation Framework, covering risk information, responsibilities, investment in risk reduction and pre/post-event cost-sharing. It says adaptation should minimise overall costs to society. National Adaptation framework | Ministry for the Environment | No comprehensive final allocation formula yet. National's framework envisages cost-sharing before and after disasters; its 2026 campaign emphasis is on practical, cost-effective resilience. National Adaptation framework | Ministry for the Environment |
| Labour | Wants to strengthen the ETS, arguing the carbon price is currently too low to deliver meaningful reductions, and recommit to the Paris Agreement. It would review forestry's role in the ETS and seek more genuine domestic reductions. Release: Labour to accelerate climate action | Supports substantial public investment in resilient infrastructure. Labour's adaptation policy was still being finalised in August, but it supported the previous government's resilience/managed-retreat work. Political parties make their climate adaptation pitch | Labour has been unusually explicit: a mix of beneficiary-pays, exacerbator-pays, central/local government funding, and contributions involving banks and insurers. Political parties make their climate adaptation pitch |
| Greens | The most interventionist approach among the larger parties: rapid fossil-fuel phase-out, electrification and making major polluters pay. Its 2026 manifesto explicitly combines emissions reduction with energy transition. Manifesto 2026 - Green Party of Aotearoa New Zealand | Wants substantially more proactive resilience, including green infrastructure, stronger central/local coordination and Te Tiriti-based adaptation. Its manifesto promises comprehensive support for communities facing increasingly severe weather. Manifesto 2026 - Green Party of Aotearoa New Zealand | Greens argue adaptation costs should be fairly shared, rather than falling disproportionately on already-exposed communities. They criticise leaving councils, insurance premiums and households to absorb costs by default. 2026 Election Q&A - Science - Science Media Centre |
| ACT | Would go substantially further in the opposite direction: scrap the 2050 net-zero target, reduce the carbon price and replace current settings with policies benchmarked against comparable countries. ACT says climate policy should reduce emissions without imposing costs competitors don't bear. ACT New Zealand | Favors practical engineering solutions—such as upgraded stopbanks, stormwater systems, roads and raised buildings—rather than using climate-risk projections to restrict property development. Political parties make their climate adaptation pitch | Emphasis is on avoiding unnecessary government expenditure and regulatory costs. ACT has not set out a large dedicated adaptation fund comparable with Opportunity's $5bn proposal. |
| NZ First | The most sceptical position among the parliamentary parties: it says it will withdraw New Zealand from the Paris Agreement and puts economic development ahead of climate policy. Political parties make their climate adaptation pitch | Focuses on concrete regional infrastructure and resilience rather than climate-policy frameworks. NZ First told the adaptation conference that adaptation should move away from slow bureaucracy. 2026 Election Q&A - Science - Science Media Centre | Relatively little detailed 2026 costing/allocation has been published. The emphasis is on practical infrastructure rather than a new climate-finance architecture. |
| Opportunity Party | Wants to restore the integrity of carbon pricing and emissions targets, electrify homes/transport and help industry move off coal and gas. It would recommit to Paris and follow Climate Change Commission advice. Climate Action - The Opportunity Party | Has one of the clearest adaptation proposals: a $5 billion Climate Resilience Fund, including $500m for nature-based solutions, plus a national insurance framework and better hazard information. Climate Action - The Opportunity Party | Explicit shared-responsibility model: central government where risks exceed local capacity/national assets; councils continue community investment; property owners bear some responsibility for foreseeable risks; insurers and infrastructure providers also have roles. Political parties make their climate adaptation pitch |
| Te Pāti Māori | Its 2026 energy policy puts a strong emphasis on replacing fossil fuels with community/Māori-owned renewable energy. It proposes a $1bn Energy Sovereignty Fund and a pathway to energy sovereignty by 2035. We Want Cheaper Power And We Want Our People To Own It. - Te Pāti Māori | There is less detailed, separately costed adaptation policy publicly available than from the Greens or Opportunity. Its climate approach puts considerable emphasis on Māori/community ownership and decision-making. | A strong emphasis on community, hapū and iwi ownership, rather than relying solely on conventional central-government/private-sector models. Te Pāti Māori did not respond to the Science Media Centre's adaptation questions by its deadline. 2026 Election Q&A - Science - Science Media Centre |
The biggest difference: mitigation vs adaptation
There are really two different arguments in this election.
On emissions, Labour, Greens and Opportunity favour maintaining or strengthening the existing climate architecture. National accepts the net-zero goal but puts considerably more weight on economic costs, technology and energy security. ACT and NZ First want a fundamental retreat from the current targets: ACT would scrap net zero, while NZ First says it would leave Paris. Release: Labour to accelerate climate action
On adaptation, the divide is less clean. Even National, Labour, Greens, Opportunity and ACT accept that New Zealand needs more flood, storm, coastal and infrastructure protection. The argument is principally over how much to invest, where protection should be built, how much development should be restricted, and who bears the bill. Political parties make their climate adaptation pitch
What does "the cost of disaster protection" actually mean?
This is becoming one of the most consequential climate-policy questions in New Zealand. The Climate Change Commission's August 2026 assessment says natural hazards, including climate change, are already costing central government and insurers more than $4 billion a year in direct costs. It also found that 97% of central-government natural-hazard spending has been on response/recovery, versus only 3% on reducing future risk. The Commission says investment in advance can potentially return up to $10 for every $1 invested, while warning that the current system still lacks clear decisions about who pays for adaptation.

That makes the parties' funding models particularly important:
- National: establish the framework first, then use a mixture of public and private/pre-event and post-event funding, with an emphasis on keeping total social costs down. National Adaptation framework | Ministry for the Environment
- Labour: explicitly split the bill between beneficiaries, polluters/exacerbators, government, councils, insurers and banks. Political parties make their climate adaptation pitch
- Greens: substantially more upfront public/community investment, with the costs distributed fairly rather than simply passed to exposed households and councils. Much delayed climate adaptation bill needs much more work - Green Party of Aotearoa New Zealand
- Opportunity: a clearly specified $5bn resilience fund, alongside risk-based contributions from property owners, insurers and infrastructure providers. Climate Action - The Opportunity Party
- ACT: favour engineering solutions and fewer restrictions/regulatory costs rather than a large new climate-adaptation bureaucracy or fund. Political parties make their climate adaptation pitch
- NZ First: prioritise conventional regional infrastructure and economic development, with less emphasis on climate-specific policy. Political parties make their climate adaptation pitch
One important caveat: a party promising $X of resilience spending doesn't mean the same thing as demonstrating that $X is enough. The independent Climate Change Commission says the country still lacks sufficiently clear national decisions on adaptation funding and cost-sharing. 2026 Progress report: National adaptation plan :: Climate Change Commission
So, rather than a simple left/right split, the 2026 choice is partly about how much New Zealand should spend now to reduce future disaster losses, how much climate mitigation should be pursued through prices and regulation, and whether protection costs should fall mainly on taxpayers, councils, property owners, insurers, beneficiaries or the businesses contributing to climate risk.
