Parliament has voted to wind up the Ministry for the Environment, ending the agency’s 40-year run as the country’s standalone environmental department and clearing the way for a new super-ministry that bundles the environment with housing, transport, cities and regions.
The Environment (Disestablishment of the Ministry for the Environment) Amendment Bill passed its third reading in Parliament on Wednesday night, 27 May 2026. The bill went through with the support of the National-led coalition, over opposition from Labour and the Green Party.
From 1 July 2026 the Ministry for the Environment’s functions will sit inside the new Ministry for Cities, Environment, Regions and Transport, known as MCERT. The new agency was formally established on 1 April 2026 and has been operating in shadow form since then, with the bill now transferring statutory functions under the Environment Act across to MCERT’s chief executive, who will also hold the role of Secretary for the Environment.
MCERT combines four existing entities into a single department. It absorbs the Ministry for the Environment, the Ministry of Housing and Urban Development and the Ministry of Transport, along with the local government functions previously carried out by the Department of Internal Affairs. The merger is part of the wider public service consolidation announced earlier this month, which aims to cut the number of government departments from 42 to about 12 by 2029 and shed roughly 8,000 public service roles.
Environment Minister Nicola Grigg told the House the change was administrative rather than substantive. “This law change is simply about form not function,” she said, arguing that statutory protections under the Environment Act and the Resource Management Act remain in place and that environmental staff will simply move across to the new ministry. Grigg said the new arrangement would lead to more practical and joined-up decision-making because housing, transport and environmental policy would sit at the same table rather than being negotiated between competing agencies.
RMA Reform Minister Chris Bishop has driven the consolidation. When the bill was introduced in February he said the new agency would be “at the heart of tackling some of New Zealand’s greatest economic and environmental challenges, from housing affordability and our infrastructure deficit to climate adaptation”. Bishop has framed the merger as a way to break down the silos that he says have slowed down infrastructure consenting, planning reform and housing supply.
The new ministry’s chief executive has yet to be permanently appointed, with the government signalling that decision is expected in the coming months.
Opposition parties argue the change downgrades the environment. Green Party environment spokesperson Lan Pham told Parliament that none of the coalition partners had campaigned on disestablishing the Ministry for the Environment and that voters had been given no chance to weigh in. “New Zealanders of all political stripes care about the environment, swim in rivers, lakes, and at the beach, and fish for kai. They know that nature is the backbone of our economy. They did not ask for this,” she said. Pham also linked the decision to wider concerns about environmental indicators, arguing the change comes “at a time when all our environmental outcomes across freshwater, air, biodiversity and oceans are going backwards”.
Public submissions on the bill were heavily one-sided. The Environment Select Committee received 588 written submissions. Only five backed the change. The remaining 583 either opposed the bill outright or wanted significant amendments to keep the Ministry for the Environment as a stand-alone agency with a dedicated chief executive whose primary loyalty was environmental policy. The select committee majority recommended the bill proceed regardless, which Newswire reported earlier in May.
Labour has called the merger backwards, arguing that placing environment alongside housing, transport and infrastructure inside one ministry creates a structural conflict of interest. Critics inside the policy community say environmental advice is most useful when it is contestable and separate, and that an integrated ministry risks producing softer advice on contentious infrastructure and planning decisions because the same chief executive is also responsible for delivering housing and roads.
Supporters counter that the previous arrangement created its own problems. They argue the Ministry for the Environment, the Ministry of Housing and Urban Development and the Ministry of Transport spent considerable time negotiating with each other rather than producing decisions, and that a single ministry with one chief executive removes a layer of friction.
The Ministry for the Environment was established in 1986 under the fourth Labour government, growing out of the Environmental Protection and Enhancement Procedures introduced in 1973. Its disestablishment is one of the largest restructures of New Zealand’s environmental machinery since the Resource Management Act was passed in 1991.
MCERT becomes operational on 1 July 2026. Existing Resource Management Act decisions, Environmental Reporting Act outputs and other statutory functions will continue under the new ministry’s chief executive from that date.
The 2026 general election is now five months away. With voters not having been asked at the ballot box about a structural change of this size, the question of whether the next government re-creates a stand-alone Ministry for the Environment is likely to feature in the campaign. New Zealand voters can compare the environmental policies of each party using the Newswire voting tool.
What do you think? Should the environment have its own dedicated ministry, or does pooling it with housing, transport and cities make for better joined-up decisions? Let us know in the comments below.
