Local Māori have opposed the expansion of New Zealand's largest gold mine, north of Dunedin, saying not enough is known about its long-term or cumulative effects on the environment.
Kāti Huirapa Rūnaka ki Puketeraki, Te Rūnanga o Moeraki, and Te Rūnaka o Ōtākou — submitting as Kā Rūnaka — said OceanaGold's application to expand its Macraes Gold Mine did not adequately address "the magnitude, severity and ongoing impact" of the effects arising from their plans.
"Furthermore, the conclusions contained in the application regarding the effects arising from the application have been reached without an assessment of the cultural impacts of the project endorsed by Kā Rūnaka," the submission said.
"It is not possible for the applicant to conclude that the effects are of an acceptable level without cultural input into their assessment."
OceanaGold applied to the Otago Regional Council, Waitaki District Council and Dunedin City Council for consent for the site-wide expansion of mining activities at Macraes, requesting public notification.
Seven submissions were published on the regional council website yesterday.
A hearing is set down for July.
Kā Rūnaka's counsel said the mining company's application lacked detailed information on the proposed expansion's effect on a range of matters including the mine's cumulative effects on water quality, the provision for appropriate and meaningful management of long-term environmental effects and the ongoing and long-term nature of its effects.
Questions remained about the expansion's cultural effects, its land restoration requirements, and its economic impact on Kā Rūnaka.
More needed to be known about the "durability and sustainability" of the offsets and mitigation measures proposed, the submission said.
The applications also lacked a "credible long-term environmental management plan".
"Kā Rūnaka has little choice but to oppose the consents sought."
Forest & Bird also opposed the application and said the proposed expansion would result in significant adverse effects on indigenous plants, animal habitat, wetlands and freshwater ecosystems.
The environmental organisation called upon the regional council to decline the application in full.
Or, if the council was of a mind to approve the application, to include "significant changes to effects management, mitigation and compensation" to account for the significant effects on indigenous species and habitats.
Otago Fish & Game also called for consideration of the long-term effects of the mine.
"Fish & Game submits that the decision-maker should be very certain that there is an extremely robust mechanism to ensure any proposed rehabilitation work — including future adaptive management actions which are not now currently known — will actually be undertaken.
"With that said, Fish & Game is not clear exactly how this could be achieved on a project which spans hundreds of years and into perpetuity, affecting countless future generations."
"In the face of such dramatic uncertainty, it may be that adopting the precautionary principle would be a helpful place to begin," Otago Fish & Game said.
Fire and Emergency NZ submitted a neutral submission but called for assurances there would be an adequate water supply available for firefighting activities as well as emergency vehicle access.
The Department of Conservation noted the application was missing an ecological enhancement area management plan as well as the cultural impact assessment.
"This means that at the time of lodging this submission there can be no certainty that the combination of conditions and management plans will be able to adequately address effects on the environment," the department's submission said.
One neighbour opposed the expansion, citing concerns about noise, air, water and light pollution.
Another raised concerns about what he described as historic consent breaches.
OceanaGold has been approached for comment.

'Trump Of The North' Will Not Seek Re-Election As Mayor
A controversial Northland mayor will not be standing for a second mayoral term. In a shock move, Kaipara Mayor Craig Jepson on Tuesday confirmed he would not be standing for the $138,441-a-year position in the October local election. Mangawhai's Jepson (67) is instead backing Kaipara District Council (KDC) Deputy Mayor Jonathan Larsen (54). Jepson appointed Larsen to the deputy role in October 2022. And Jepson - who has referred to himself as the "Trump of the North" - will be standing as a councillor in his Kaiwaka-Mangawhai ward. The position pays $68,719 annually. Jepson's about-turn comes after consistently indicating he will be standing for a second tilt at the Kaipara mayoralty. He would not be drawn on the reason for the tack change, other than to say he wanted to step down from the top job and spend more time on issues close to his heart as a councillor. Jepson's political move comes as first-term KDC councillor Ash Nayyar said for the first time that he would be taking a tilt at the top job. Dargaville's Nayyar believed too many KDC decisions were being made behind closed doors, and unnecessary pet projects were being adopted by the council. He said he was unhappy KDC, in his opinion, had generally ignored the voice of the people during public consultation. Nayyar claimed Kaipara's west had been neglected and as Mayor he would do all parts of the district justice. He has a Master of Business administration, Bachelors of Commerce and Law and 40 years' banking experience. Topuni's Larsen was first elected onto KDC in 2010. He resigned in protest in August 2012, just under two years into a three-year term. He said he left over his dissatisfaction with the council making closed-door decisions on the future of the controversial Mangawhai wastewater scheme, including $30 million in extra spending on the project. Larsen said he had brought this matter to the attention of the Auditor-General. government ministers and Ombudsman. The government appointed commissioners to run KDC in September 2012. Larsen was re-elected in 2016 and has been a KDC politician since. If successful in October, it would see him elected for a fifth term. He has a Bachelor Science, and an Executive Master of Business Administration with first class honours. Jepson's big calls as mayor In his first controversial move, Jepson canned karakia from council meetings in November 2022, just two months into the job. KDC later became the only council to can its Māori ward in August 2024 after government law changes - one of Jepson's proudest achievements, and one which was also backed by Larsen. Jepson said he was proud of his council's "small" 8.2 percent rates rise for 2025/2026. He said another positive move was his council withdrawing from national councils' representative body Local Government New Zealand. The mayor said there were a range of issues he wanted to work on as a councillor. Getting rid of mangroves would be one of the major issues he wanted to invest in. "I want to get rid of mangroves from our harbours, not just Mangawhai Harbour, but Kaipara Harbour and the whole of Northland," Jepson said. Jepson said he also wanted to boost the fight against Auckland's Dome Valley landfill - which is just across the local political border in Auckland Council - and educate people about the merits of waste to energy technology. He has strongly campaigned for such a plant in Kaipara. Larsen and Jepson jointly conducted information visits to constituents around Kaipara on the plants. Meanwhile, Jepson has long-challenged current science backing climate change. KDC axed its Ruawai-based Northland climate change pilot midstream. KDC also got rid of its key climate change policy in 2023 in a move brought to the council table by Larsen. Larsen said that even if climate change was a reality, the actions of Kaipara's 18,000 ratepayers would not make a jot of difference in a world with 8 billion people. Jepson was elected with a big majority in 2022. Jepson said that many had encouraged him to stand again, to do a "lap of victory", but being a local politician was not about ego. It was about what was best for the district.

Budget benefits southern people
A standout of the Budget, that I believe will pump a lot of energy into the Gore area is Investment Boost. The programme gives tradies, farmers, and other businesses a tax incentive to invest in new tools and equipment to boost productivity and lift wages. Businesses can now deduct 20% of the cost of new machinery, tools and equipment off their taxable income. This is on top of existing depreciation meaning a much lower tax bill in the year of purchase. If a farmer wanted to buy a new tractor for $150,000, they would be able to immediately deduct $30,000. Investments like this pump money directly into our local economy, making everyone better off. The Budget also includes $164 million over four years to expand urgent and after-hours healthcare, including better access to diagnostics, urgent medicines and 24/7 on-call clinical support. Over the next two years improved services will be rolled out to rural communities in places like Balclutha, Lumsden and Roxburgh. I am also pleased to see that the Budget will help up to 66,000 more SuperGold cardholders with their rates payments, with a new income abatement threshold to assist SuperGold cardholders being introduced from July 1. Another excellent development for the South is the investment for Milford Sound announced last week. Certainty for cruise ship access and the retention of the Milford Aerodrome is incredibly important for this community. With many of the sound's visitors moving through our region, this $15.2m investment will bring confidence for Southland and will help ensure a strong future. Reforms to Fish & Game New Zealand are on the way. The changes will modernise and strengthen the organisation, as well as improve the management of hunting and fishing resources and advocacy, while maintaining local control. Legislation will be introduced this year, and the select committee will provide an opportunity to provide feedback on the proposals. Finally, it was great to see such a packed lineup of events come to Gore for the Bayleys Tussock Country Music Festival. The festival is a great example of our region leading the way in the country music scene.
