The Hauraki District Council has approved a scaled-back version of OceanaGold’s request to extend the Martha Mineral Zone in Waihī. The decision, made on March 27, follows a comprehensive review process that included technical assessments, community submissions, and independent recommendations.
OceanaGold initially sought to rezone 47 properties surrounding the Martha Pit from residential and commercial classifications to a mineral zone, which would allow for future surface mining applications. However, after reviewing submissions and hearing evidence, the independent Hearing Panel recommended reducing the rezoning area. The Council adopted this recommendation, approving only 26 properties for rezoning.
The Panel found that some proposed areas were too close to the town’s commercial center and residential areas, making them unsuitable for mining activities. As a result, the Council removed Town Centre-zoned properties and residential land on the western edge from the rezoning plan.
The application process, which began with public notification in February 2024, drew 78 submissions and three further submissions. Public hearings were held in December 2024 and February 2025, allowing community members to voice their perspectives. Mayor Toby Adams acknowledged the thorough review process and thanked all involved, stating that the decision balances expert recommendations with community interests.
Those affected by the decision, including OceanaGold and submitters, have until May 16, 2025, to file appeals. The full decision and amendments are available on the Hauraki District Council website and at local council offices and libraries.
In a separate but related development, OceanaGold has also applied to the Environmental Protection Authority (EPA) for approvals related to its Waihi North Project. The Council is awaiting confirmation from the EPA on whether the application is complete. If accepted, an assessment panel will be appointed, and the Council will have 20 working days to provide feedback.
These decisions are crucial in shaping the future of mining in Waihī, balancing economic interests with environmental and community considerations.
In response to the council decision, Alison Paul, Senior Vice President Legal and Public Affairs for Oceana Gold issued the following statement:
‘The Company will now take the time to review our application for Plan Change 6 and the relevant options. It is important to note that any change to the Martha Mineral Zone itself does not authorise new physical mining beyond that which is already approved.
The technical studies for the Martha Open Pit Project are ongoing, and a partial change to the MMZ will also require a review of the proposed plans. At present, OceanaGold’s priority is the Waihi North Project, and as such, we do not currently have an indicative timeframe on any next steps relating to the Martha Open Pit Project.
We will ensure that the community is kept up to date on the progress of the Martha Open Pit Project, including details of the proposed project as they become available. ‘
