RMA reform clears a high bar even if opponents are already sharpening their repeal plans

The prize is real, and so is the drag

Strip away the politics and the case for replacing the Resource Management Act 1991 is overwhelming. A Ministry for the Environment analysis of 1,000 consent applications found that up to 46% of current applications may become unnecessary under the new regime, roughly 15,000 to 22,000 consents no longer required each year based on 2023/24 volumes.

For developers and infrastructure firms, that is the whole pitch. In its submission on the bills, Master Builders cited a 2021 Infrastructure Commission estimate that consenting for infrastructure costs $1.29 billion a year, and called the reforms a once-in-a-generation chance to fix a broken system. Federated Farmers RMA reform spokesman Mark Hooper told RNZ the current Act had created “a litigious system” that made consenting expensive, slow and uncertain.

Nobody serious disputes the problem. The fight is over whether the fix works.

The late amendments changed the game

After the Planning Bill and Natural Environment Bill passed their second reading on 4 August 2026, around 20 late amendments were introduced after the select committee stage. Green Party environment spokesperson Lan Pham called them “completely out the gate”, and much of the opposition has now stopped trying to negotiate, waiting instead for a change of government.

That matters for business because the most contentious provision is a genuine commercial wildcard.

The $2 billion compensation gamble

The regulatory relief provision requires councils to financially compensate private landowners when planning rules restrict certain land uses. The Ministry for the Environment estimated the cost at anywhere between $7 million and $2 billion depending on how councils behave. In Auckland alone, roughly 26,000 hectares of private land would be in scope.

Environmental Defence Society’s Dr Greg Severinsen called it “neoliberal ideology gone crazy”, warning in a July 2026 analysis that a relief framework would be “costly, bureaucratic, litigious and fraught with legal ambiguity” and posed a serious risk of grinding the whole system to a halt.

A separate August 2026 analysis spelled out the mechanics. Councils would have to estimate compensation across every affected property, obtain legal advice on uncertain statutory terms, and field submissions from thousands of landowners, developers and community groups. Consultant Martin Jenkins put the range at “an astonishing” $7 million to $2 billion nationally. The verdict was blunt: the government wants a system that is faster, simpler and less litigious, and “regulatory relief achieves the opposite”.

The likely real-world outcome is not compensation but avoidance. Faced with open-ended liability, many councils will simply drop environmental protections rather than trigger the regime. That is a mechanism for shifting costs off the balance sheet, wrapped in a legal minefield for anyone trying to plan around it.

Power moves to Wellington

The bills also hand the Environment Minister expanded power to approve developments even where environmental limits would otherwise be breached, provided “public benefits” outweigh the harm. Parliamentary Commissioner for the Environment Simon Upton, a former National minister, said the legislation gives “no particular priority to environmental outcomes” and amounts to “a wholesale rejection of localism”. Labour’s Rachel Brooking warned the vague criteria would create “a whole lot of work for environmental lawyers”, a pointed irony for a reform sold on cutting litigation.

The Three Waters parallel is the business risk

Here is what should worry anyone planning capital expenditure. Treasury’s Gateway Review rated the reform programme amber/red, signalling significant delivery problems, and the Environment Committee recommended delaying the transition to at least the end of 2029. The Institute of Directors noted several parliamentary stages still lie ahead.

Labour has signalled it would reverse key elements, particularly on iwi partnerships and regulatory relief, if elected. That creates a direct echo of Three Waters, a reform businesses and councils spent years preparing for only to watch it reset when the government changed.

For developers, infrastructure firms and councils, the sharpest question is not whether the RMA needed replacing. It is whether you dare build a project pipeline around a regime that may not survive the next ballot. Reform that cuts consenting drag is worth having. Reform that swaps one form of legal uncertainty for another, then gets torn up in 2029, is the worst of both worlds.
