For the 2026 New Zealand general election: What do parties propose about freshwater, pollution, biodiversity and resource management?
2026 New Zealand general election: Environment and natural resources policies
The main differences between New Zealand's political parties concern four questions:
- Freshwater: How strictly should rivers, lakes and aquifers be protected, and who should decide how water is allocated?
- Pollution: Should farmers, industry and wastewater operators face tighter limits and enforcement?
- Biodiversity: How much land and ocean should be protected, and how should conservation be funded?
- Resource management: Should environmental regulation prioritise ecological protection, property rights, or faster economic development?
The following is a comparison of the 2026 election positions, focusing on National, Labour, the Greens, ACT, NZ First, Te Pāti Māori and the Opportunity Party (TOP).
These are announced policies and campaign commitments, not necessarily enacted law. The comparison draws on the parties' published positions and 2026 policy trackers, including material verified in October 2026.

1. Freshwater and water quality
Rivers · lakes · groundwater · drinking water · agricultural runoff
| Party | Main freshwater position |
|---|---|
| Greens | Stronger national water-quality standards, lower nitrate limits, reduced synthetic nitrogen fertiliser use and stricter wastewater controls. |
| Te Pāti Māori | Māori participation and decision-making in freshwater governance, enforceable ecological limits and no trading of water rights. |
| TOP | Reinstate Te Mana o te Wai, strengthen pollution enforcement, introduce controls on nitrates and phosphates, and restore wetlands. |
| National | Supports water infrastructure and storage, including up to $300 million in low-cost farm water-storage loans and easier irrigation consenting. |
| ACT | Wants to remove Te Mana o te Wai requirements from resource consenting, particularly in relation to farming. |
| Labour | Its headline 2026 environmental commitments are less detailed on freshwater in the available policy tracker; it proposes an urgent review of the Emissions Trading Scheme. |
| NZ First | Its headline environment proposals are more focused on resource development and energy security than a new comprehensive freshwater-quality programme. |

Important differences
- Te Mana o te Wai: This is a significant dividing line. The Greens and TOP support restoring or strengthening its role. ACT wants to remove its requirements from resource consenting.
- Agricultural pollution: The Greens propose reducing synthetic nitrogen fertiliser use and addressing stocking rates at catchment level. TOP proposes nitrate and phosphate controls.
- Water allocation: Te Pāti Māori emphasises Māori decision-making, ecological health and rejecting the privatisation or trading of water rights.
- Drinking water: The Greens specifically propose lowering the nitrate limit for drinking water and strengthening monitoring and enforcement.
2. Pollution and waste
Agricultural runoff · wastewater · industrial contamination · rubbish · marine pollution
| Party | Main proposals |
|---|---|
| Greens | Stronger wastewater discharge rules, lower drinking-water nitrate limits, reduced synthetic fertiliser use and stronger monitoring of water quality. |
| TOP | Stronger enforcement against polluters, nitrate and phosphate controls, riparian planting, wetland restoration and a national container-deposit scheme. |
| National | $30 million from the Waste Disposal Levy to scale up the cleanup of contaminated Crown land. |
| ACT | Proposes higher penalties for illegal rubbish dumping, including increasing infringement fees from $400 to $1,000 and $2,000 fines for repeat offenders. |
| Te Pāti Māori | Focuses on freshwater protection, Māori authority over water and addressing drinking-water and water-service failures in Māori communities. |
| Labour | Its headline environment commitments in the current tracker do not include a comparably detailed new pollution package. |
| NZ First | Its published headline environment proposals focus more on resource development, energy and infrastructure than a comprehensive new pollution-control programme. |

One distinction worth noting: pollution policy is not just about litter and industrial waste. Agricultural nitrogen, phosphorus, sediment and wastewater discharges are particularly important when comparing parties' freshwater policies.
3. Biodiversity and conservation
Native species · wetlands · forests · conservation land · marine ecosystems
| Party | Main proposals |
|---|---|
| Greens | Establish a sovereign biodiversity fund; increase funding for invasive-species control; protect all remaining natural wetlands; create ecosystem-regeneration jobs; expand marine protection and end bottom trawling. |
| Te Pāti Māori | Strengthen Māori and iwi-led environmental stewardship, freshwater authority and kaitiakitanga. |
| TOP | Establish a $500 million nature-based solutions fund; support biodiversity credits for Significant Natural Areas; restore coastal habitats and strengthen native forestry standards. |
| National | Provide $100 million annually from the International Visitor Levy to the Department of Conservation; establish additional marine protections and support conservation funding. |
| ACT | Emphasise hunting access and changes to conservation-land regulation, including transferring some hunting-related regulatory responsibilities from DOC to the Civil Aviation Authority. |
| Labour | Its headline 2026 environment proposals are less developed on biodiversity than those of the Greens and TOP in the policy tracker. |
| NZ First | Supports increased resource development, including investigating oil, gas and geothermal resources. Its headline environment proposals contain fewer new biodiversity-protection commitments. |

Marine biodiversity
There are some particularly clear differences concerning the ocean.
Greens
Protect at least 30% of New Zealand's ocean, establish a national system of no-take marine protected areas and phase out bottom trawling.
TOP
Protect 30% of ocean territory by 2035, phase out bottom trawling, oppose seabed mining and move towards ecosystem-based fisheries management.
Te Pāti Māori
Emphasise Māori authority, kaitiakitanga and protection of natural resources for future generations.
National
Proposes additional marine protection, including a new reserve off Waiheke Island, expanding Goat Island marine reserve and restrictions on certain commercial fishing activities.

4. Resource management and environmental law
This is arguably the most important structural issue because resource-management legislation determines how freshwater, land, minerals, infrastructure and ecosystems are regulated.
| Party | General approach |
|---|---|
| Greens | Repeal the Fast-track Approvals Act, strengthen environmental protections and support greater community, iwi and hapū participation in decisions. |
| Te Pāti Māori | Support Te Tiriti-based environmental governance, Māori authority over natural resources and stronger recognition of kaitiakitanga. |
| TOP | Reinstate Te Mana o te Wai, strengthen environmental standards and limit ministerial overrides of environmental protections in fast-track projects. |
| Labour | Supports reviewing environmental and resource-management settings, but its headline 2026 environment commitments provide less detail on a complete alternative framework. |
| National | Supports replacing the Resource Management Act framework and streamlining consenting to facilitate development and infrastructure. |
| ACT | Emphasises reducing regulatory restrictions on property owners, farmers and developers, including removing Te Mana o te Wai requirements from consenting. |
| NZ First | Emphasises development, infrastructure and resource security, including oil and gas exploration and a special economic zone at Marsden Point. |

What are the underlying differences?
There are three broad approaches:
- Stronger environmental limits and ecological restoration
The Greens propose stronger environmental regulation, ecosystem restoration, biodiversity funding and reduced pollution. TOP also supports stronger environmental limits, restoration and changes to fast-track decision-making.
- Māori authority and environmental governance
Te Pāti Māori puts particular emphasis on Māori decision-making over freshwater and natural resources, the Treaty relationship, kaitiakitanga and iwi and hapū governance.
- Development and streamlined regulation
National, ACT and NZ First place greater emphasis on development, infrastructure, resource use and reducing regulatory barriers. They differ in their specific approaches, but all place considerable importance on enabling economic activity.
Labour occupies a different position from both the current governing parties and the more environmentally focused opposition parties, although its detailed 2026 commitments need to be considered issue by issue.

6. Where to investigate further
For a more detailed examination, I would particularly recommend these three resources:
- Policy.nz – 2026 environmental policy comparison: Compare individual policies covering freshwater, pollution, conservation, oceans and waste.
- Greenpeace Aotearoa – 2026 environmental scorecards: Examines party responses to 20 environmental questions, including freshwater, conservation and environmental law. Note that Greenpeace is an environmental advocacy organisation, so its scoring reflects its own environmental criteria.
- Know Your Vote – 2026 election guide: Provides policy descriptions sourced from party websites and press releases.
7. An important consideration: MMP and coalition agreements
A party's environmental promises are not necessarily what will become government policy.
Under New Zealand's MMP system, parties generally need to negotiate to form a government. Environmental policies can be retained, modified or abandoned during coalition negotiations. They must also survive the legislative process. Know Your Vote
For this reason, it is worth examining not only what each party promises, but also which policies it might insist on during coalition negotiations.
My suggestion for evaluating the environmental policies: Look particularly closely at four practical questions:
- Will freshwater quality measurably improve, including in agricultural catchments?
- Will polluters face enforceable limits and meaningful penalties?
- Will native biodiversity, wetlands and marine ecosystems receive stronger legal protection and adequate funding?
- Will resource-management reforms maintain independent environmental safeguards and meaningful public and Māori participation?
These questions help distinguish broad environmental aspirations from specific, measurable commitments.
