Councils face an uncosted bill just as rate caps bite hardest

The problem the current system genuinely has

Start with the case for reform, because it is real. Consent costs rose 70% between 2014 and 2019, the time to get a decision jumped 150% from the early 2010s to 2021, and infrastructure consents alone cost $1.3 billion a year, at the extreme end of international benchmarks. The government’s own March 2025 Regulatory Impact Statement put the total cost of the current system at $39 billion in present value over 30 years.

Nobody who has tried to build anything in New Zealand thinks the RMA works. Minister Chris Bishop has framed the reform around a $13.3 billion saving over three decades, with the blueprint headline figure at $14.8 billion. That is not trivial. But the Environment Select Committee’s recommended changes, running past a thousand pages, have introduced costs the headline figure never captures.

The bill lands on councils, and rate caps stop them paying it

The new regulatory relief scheme requires councils to compensate landowners when environmental protections restrict land use. A ministry-commissioned Martin Jenkins report put the cost to councils at somewhere between $7 million and $1.9 billion. A range that wide is not an estimate, it is an admission that the government does not know what it has created. Analysis of the select committee’s version cites figures of up to $2 billion.

Auckland alone has more than 17,000 properties with significant ecological protections across 26,000 hectares, including the Waitakere Ranges. Keeping those protections could cost millions in compensation. Small rural councils in the South Island high country face the same maths with a fraction of the capacity.

And the timing is brutal. The government is simultaneously pushing rate caps of 2 to 4%, which strangle the very revenue councils would need to fund the liability. Councils told the committee they were unlikely to be able to afford it. Hawke’s Bay Council put it flatly in its submission: the reform “would shift the cost of environmental enforcement to councils”. The practical outcome is that many protections simply get dropped, which is not neutral for ratepayers or for property values near sensitive land.

A limit you can negotiate is not a limit

Under the revised framework, councils must weigh economic aspirations against environmental harm when setting limits. A limit stops being a hard biophysical threshold and becomes a tradeable one. Any activity, from dairying to data centres, can breach a limit if the minister decides the public benefit outweighs the harm.

Here is why business should care beyond the green politics. Degradation does not vanish, it accumulates as future remediation cost that eventually lands on public accounts, water infrastructure bills, or the agricultural sector’s access to premium export markets. The March 2025 Supplementary Analysis Report noted New Zealand had already lost 90% of natural wetlands and two-thirds of indigenous forest since the RMA came in. Even BusinessNZ, in its February 2026 submission, argued limits should be set on strong scientific grounds and not tampered with lightly, a more cautious position than the committee took.

The certainty problem that kills the whole pitch

The entire justification for reform is certainty. Yet Parliament’s own Regulation Review Committee flagged a “Henry VIII clause” letting the minister reshape the system through secondary instruments, direction that councils must implement without recourse to the courts. The Parliamentary Commissioner for the Environment called it “a wholesale rejection of localism”.

A regime one minister can rewrite by decree is not a stable investment platform, and experts warn the reform trades certainty for speed. Labour has already branded the bills an “embarrassment” it intends to revisit, and even The Spinoff’s analysis judged the reforms on shaky ground. As Newsroom’s Dr Greg Severinsen warned, the prospect of repeal by a new government is real and would “continue the expense and uncertainty caused by flip-flopping our resource management”.

What this actually means

The pro-growth case for RMA reform is sound. The problem is the government bundled genuine consenting reform with gutted limits and an uncosted liability transfer, then advertised only the saving. For any business planning a project that depends on predictable consenting and solvent local councils, the honest question is not whether the RMA needed fixing. It is who pays for the downstream costs the headline figure conveniently leaves out, and whether the whole thing survives the next election intact.
