A loophole the minister did not see coming
New Zealand’s Conservation Amendment Bill passed its first reading on 17 June with 68 votes to 54. Conservation Minister Tama Potaka called it the most significant reform to conservation law in 40 years. Within 24 hours, he was acknowledging an unintended loophole that could inadvertently open nearly half the Coromandel Peninsula to mining activity, based on niche land classifications that historically carried stronger protections.
Potaka committed to reviewing the wording. That is not a reassuring sentence for anyone making long-horizon capital decisions about land the Crown controls.
The bill has genuine upside buried under sloppy process
Strip away the controversy and there are real efficiency gains in this legislation. DOC says 30 to 40 percent of concession applications would no longer require individual processing, addressing a system that has been a bottleneck for tourism operators and infrastructure developers for years. International visitor access charges are projected to raise $60 million annually for reinvestment. Tourism on conservation land already generates $5.3 billion a year and supports more than 1,600 businesses.
Those are gains worth pursuing. But they are now entangled with a drafting process that has visibly failed quality control.
Post-consultation changes nobody was consulted on
The Coromandel loophole is the most vivid symptom of a deeper problem. Documents obtained by The Spinoff reveal that in June 2025, after public consultation had already closed, Cabinet directed the minister to amend the Conservation Act’s purpose statement to ensure reforms “enable greater economic development on conservation land.” Three amendments to the Act’s core purpose were inserted at that point, including making development a subsidiary function of DOC.
The government’s own analysis acknowledged the primary objective was enabling greater economic development, with mitigating legal challenge risk as a secondary concern. These changes were never subject to public scrutiny. The Environmental Defence Society warned directly: “These clauses appear to have been inserted very late in the process and were not part of engagement on the Bill.”
EDS chief operating officer Shay Schlaepfer says the bill’s language requiring DOC to enable development “to the greatest extent practicable” is “completely inappropriate” and could allow open-cast mining on the conservation estate.
The scale of land at risk is not small
Forest & Bird’s mapping analysis suggests up to 60 percent of current conservation land could fall under the new disposal or exchange provisions. Forest & Bird chief advisor Richard Capie says the maps make clear what “impenetrable” proposed legislation can mask. The Coromandel Watchdog of Hauraki has flagged ongoing proposals linked to gold exploration around Wharekirauponga, making the loophole far from abstract.
This is not a fringe concern. One-third of New Zealand’s land mass sits under conservation management. The rules governing it are being rewritten with acknowledged errors in the draft.
A cash-strapped department asked to referee its own land sales
One underreported structural problem: the bill’s revenue framework potentially puts DOC in the position of recommending land for disposal while benefiting financially from the proceeds. A department that has absorbed $135 million in cuts this term is not well-positioned to make impartial calls on what to protect versus what to sell. That is a conflict of interest baked into the design.
Meanwhile, in November 2025, Cabinet finalised amendments to consent pathways for quarrying and mining, explicitly targeting a doubling of mineral exports to $3 billion annually by 2035. The Conservation Amendment Bill does not exist in isolation. It sits alongside a broader extraction agenda that makes the “unintended” loophole look uncomfortably convenient.
Capital hates surprise rule changes
Pro-business reform of conservation concessions is overdue. Nobody benefits from a system where tourism operators wait years for approvals. But the investment case for any project touching conservation land depends on regulatory certainty, and this bill undermines exactly that.
A bill that reaches Parliament with a loophole large enough to accidentally expose a major region to mining, that contains purpose amendments inserted after consultation closed, and that lowers disposal thresholds for up to 60 percent of conservation land is not a bill that inspires confidence in the process. Public submissions close 2 July 2026. The select committee will determine whether the government treats the acknowledged errors as symptoms of a rushed job or simply patches the most embarrassing one and moves on.
