Why a fight over Waikato River rules has the government and iwi clashing
The government is putting farming rules designed to protect the Waikato and Waipā rivers on hold until 2032, and Waikato-Tainui says that undermines a Treaty settlement and the health of the rivers.
The rules, called Plan Change 1, are part of a wider overhaul of the Resource Management Act (RMA), the main law governing how New Zealand's environment is managed.
Resources Minister Shane Jones, speaking as New Zealand First's Deputy Leader, told RNZ the changes would pause Plan Change 1 and said the pause was likely to become permanent. Jones said Plan Change 1 "must be paused before it becomes a bureaucratic death sentence for farmers and growers across the region" and that "Plan 1 was going to terminate veggie growing in Waikato, and New Zealand First will never acquiesce with the termination of food production in Waikato" (RNZ).
Jones acknowledged the Treaty settlement for the Waikato River was "not to be deprecated," but said "food security cannot play second fiddle to any Treaty settlement or any regional council planning initiative." He also promised to campaign on spending $50 million to help eradicate koi carp, an invasive pest fish, in the Waikato area, arguing the new planning system would achieve much the same outcomes as Plan Change 1.
RMA Reform Minister Chris Bishop said the changes would remove unnecessary complexity, better reflect real-world farming and growing practices, and provide more certainty for investment and day-to-day operations. The changes include removing resource caps, expanding the definition of "existing use," extending permits for water infrastructure to 35 years, allowing councils to permit activities already harming waterways so long as those effects are reduced over time, and changing the indigenous biodiversity test from "no net loss" to "protect significant indigenous biodiversity." Bishop said the amendments would also include "targeted action on Plan Changes 1 and 2" to give farmers and growers in the Waikato and Manawatū-Whanganui certainty while the new planning system is set up (RNZ).
Federated Farmers welcomed the pause, saying it gave farmers "much needed breathing room" while the resource management system was overhauled.
Waikato-Tainui's response was sharp. The iwi said it was "unacceptable" to pause Plan Change 1 until 2032, calling it an override of court decisions in favour of the government's donors and warning it would subject the Waikato catchment to "another six years of degradation" (RNZ). The NZ Herald reported the pause is described as the first step in an 80-year scheme to restore the Waikato and Waipā rivers (NZ Herald).
Plan Change 1 is a set of farming rules from the Waikato Regional Council aimed at protecting the rivers by controlling nitrogen, phosphorus, sediment and bacteria across the catchment area. It requires farmers and landowners to identify and manage environmental risks through Farm Environment plans. The rules come from Te Ture Whaimana o Te Awa o Waikato, the Vision and Strategy for the Waikato River, which was negotiated between iwi and the Crown as part of the Waikato-Tainui Treaty settlement. Under law, this vision and strategy takes priority over other regional plans and national policy statements.
The Environment Court issued a ruling in June directing the Waikato Regional Council to make 20 specific changes, which would have finalised Plan Change 1 once completed. Because the court was involved, the government's pause sets aside a legal process that was close to finishing.
The Waikato-Tainui Raupatu Claims (Waikato River) Settlement Act 2010 records that pollution, degradation and development of the Waikato River, its lakes, streams and wetlands have caused the decline of once rich fisheries (legislation.govt.nz).
The broader context here is a clash between two legal frameworks with different origins. Te Ture Whaimana comes from a Treaty settlement and legally takes priority over regional plans and national policy statements. The government's pause, on the other hand, is a policy decision written into legislation that replaces the RMA. Waikato-Tainui's argument that the pause overrides court decisions points to that tension: the Environment Court's June ruling was the final step in a long legal process, and the government is stepping in before that process finishes.
Jones's suggestion that the pause may become permanent raises the stakes further. If the new planning system under the Natural Environment Bill eventually replaces the RMA framework where Plan Change 1 sits, the rules may never come into force at all. That would leave the river's protection dependent on whatever environmental limits the new system sets, which, as Bishop outlined, will no longer include resource caps and will weaken the indigenous biodiversity test from "no net loss" to "protect significant indigenous biodiversity."
For farmers, the immediate effect is relief from compliance costs and regulatory uncertainty. For the Waikato catchment, it means the nutrient, sediment and bacteria controls Plan Change 1 would have imposed stay on hold. For the Crown-iwi relationship, it puts a Treaty settlement directly at odds with the government's resource management reform agenda.
