The Green Party has put clean water and the health of the ocean at the centre of its election campaign, launching a policy package that would ban bottom trawling on parts of the seabed and force a sharp cut in the amount of nitrate allowed in drinking water.
Co-leaders Marama Davidson and Chlöe Swarbrick unveiled the plan, called Drink Swim Fish, in Wellington on Monday. It bundles eight different measures into one programme the party says would reverse years of decline in rivers, lakes, aquifers and coastal waters. The launch sets up one of the clearer environmental dividing lines heading into the 7 November general election.
At the heart of the package are three headline moves. The Greens would phase out bottom trawling on seamounts along with set netting and dredging, legally protect 30 percent of New Zealand’s ocean, and lower the nitrate limit for drinking water. They would also strengthen the rules for wastewater discharges and hand the water regulator, Taumata Arowai, stronger enforcement powers to make polluters comply.
The drinking water change would be the most far reaching for everyday households and for farming. The current maximum for nitrate in drinking water sits at 11.3 milligrams per litre, measured as nitrate nitrogen. The Greens want to move towards the much tighter standard used in Denmark, which is close to 1.3 milligrams per litre. To get there the party would phase out synthetic nitrogen fertiliser and cut stocking rates catchment by catchment, so the reduction is tied to the pressure each waterway is actually under.
Davidson framed the policy as a matter of basic fairness. In the party’s statement she said, “Clean, healthy water is a human right, and has been a way of life in Aotearoa for many generations.” She added that the package “will reverse the widespread degradation of our environment, and protect human and ecological health from corporate greed.”
She also pointed to public health, saying up to 100,000 people fall ill from unsafe drinking water in New Zealand every year, a figure the party attributes to weak rules and contaminated supplies. That claim rests on estimates of waterborne illness rather than a single confirmed count, and the true number is hard to pin down, but it captures the scale the Greens say the country is dealing with.
Swarbrick tied the environmental case to the economy. “There is no economy without the environment. When the Government fails to protect our environment we all pay the price in clean-up costs, in our people and animals getting sick, let alone the impact on our economy,” she said. She argued that “safe drinking water, a swim at the local beach, and catching some snapper on the weekend should not be too much to ask in this beautiful country,” and said only the Greens would “fix the rules so the health of our communities and environment always come first.”
The ocean measures land at a pointed moment. Fisheries scientists have warned that tarakihi, one of the fish most New Zealanders know from the takeaway shop, has been pushed close to collapse on the east coast. The Greens say ending bottom trawling on vulnerable seabed features and reviewing the Quota Management System, the framework that sets commercial catch limits, would give depleted stocks a chance to recover. The party would also back iwi-led conservation and give more weight to local guardianship of the sea.
The response from the Government was quick and unimpressed. Prime Minister Christopher Luxon said a broad ban on bottom trawling would be “very difficult”, pointing to the roughly 9,000 people who work in the wider seafood sector and an industry worth about 2 billion dollars a year. His argument is that jobs and export earnings, much of it in regional towns, cannot simply be switched off.
Federated Farmers took aim at the fertiliser plan, warning that phasing out synthetic nitrogen would “significantly hike the cost of food” by cutting the amount farmers can grow on the same land. The lobby group has long argued that blunt national limits fail to reflect the wide differences between catchments and farming systems.
Not everyone thought the Greens went far enough. Greenpeace welcomed the direction but pushed for faster action, urging that a bottom trawling ban be in place by the end of 2027 rather than phased in over a longer horizon.
For voters the package draws a sharp contrast. The Green Party is betting that clean drinking water and a swimmable local river are issues people feel directly, and that the trade offs with farming and fishing are ones a chunk of the electorate is willing to make. The Government is betting the opposite, that jobs and food prices will weigh more heavily once the detail sinks in. Which way that argument breaks is likely to be one of the tests of the campaign.
