Otago gold mine fast-track application paused again over 600 pages of new information

Santana Minerals has paused its fast-track application for an open-cast gold mine in the Dunstan Mountains near Cromwell for a second time. The company has accepted a 10-working-day suspension so the expert panel and environmental groups can review 600 pages of new information Santana submitted. (RNZ)
The fast-track panel ruled that denying environmental groups a chance to respond to the new documents would violate natural justice — the legal principle that parties affected by a decision must have a fair chance to be heard. The suspension follows an earlier pause in the same application.
The project, officially called the Bendigo–Ophir Gold Project on the government's fast-track consenting portal, targets a $4.4 billion gold deposit. Matakanui Gold Limited, the subsidiary company, lodged the main fast-track application on 31 October 2025, and the consenting body deemed it complete on 21 November 2025. (fasttrack.govt.nz)
If approved, the mine would consist of a 1000-metre-by-850-metre open pit, three smaller satellite pits and a tailings dam — a structure that holds the leftover waste material from mining. The new material Santana submitted included a social impact assessment that was initially left out of the application, along with scientific modelling on water quality, ecotoxicity (how toxic substances affect living things) and native lizard relocation.

The panel raised pointed questions about the lizard relocation plan. Santana proposes moving more than 100,000 lizards from the mine site, a rescue the panel noted could cost tens of millions of dollars. Expert consensus, however, is that long-term survival rates for the relocated animals are likely to be low. The panel also asked whether Santana was willing to indemnify the public against the costs of a "catastrophic failure" of the mine — meaning whether the company would financially cover any public costs if something went badly wrong.

Kā Rūnaka, the collective of rūnaka (councils) representing mana whenua — the iwi with customary authority over the area — has filed its preferred set of conditions for the project while reserving its position, according to Santana Minerals. (RNZ)
Santana Minerals chief executive Damian Spring told shareholders there would not be any further delays to the application. The panel's target timeline for a draft decision has moved to the week of 30 November, with a final decision set down for 20 January 2027. (RNZ)
The Bendigo–Ophir application is being processed under the Fast-track Approvals Act 2024, which established a permanent approvals system for infrastructure, housing and development projects with regional or national benefits. The Act replaced two earlier fast-track regimes: the COVID-19 Recovery (Fast-track Consenting) Act 2020, a temporary measure in force from 2020 to 2023, and the Natural and Built Environment Act 2023, which was introduced and repealed in the same year. The Environmental Protection Authority maintains a separate website for the current fast-track regime. (EPA)
The broader context here is what the natural justice ruling signals about how the panel intends to handle late-stage submissions under the 2024 Act. The legislation was designed to compress consenting timelines for projects of regional or national significance, but the panel's insistence on giving environmental groups time to respond to 600 pages of new material — including a social impact assessment that was initially omitted — suggests the regime's procedural floor may be firmer than applicants and some ministers anticipated. The question about public indemnity against catastrophic failure goes beyond standard consenting conditions and into the territory of financial assurance, which could set a precedent for how risk is allocated for other fast-track mining projects.
The lizard relocation scrutiny also raises a practical tension. The panel accepted that experts doubt the long-term survival of relocated animals, yet the rescue operation itself carries a price tag in the tens of millions. If the panel requires the relocation to proceed despite low expected survival rates, the condition functions more as a cost burden than a conservation measure. If it does not require relocation, the ecological effects of the mine on native fauna would need to be addressed through other means. Either way, the panel's questioning indicates it is testing the robustness of the applicant's environmental mitigation package rather than rubber-stamping it.
Kā Rūnaka's decision to file mana whenua conditions while reserving its position is a deliberate posture — participating in the process without conceding the broader question of whether the mine should proceed. That leaves the group room to maintain its position through to the panel's final decision on 20 January 2027.
