The Māhinerangi Wind Farm project in Otago has been granted Fast-track approval.

This is the 26th project and the sixth renewable energy project to receive approval through the fast-track process.

Tararua Wind Power Limited lodged a substantive application in November 2025 to expand and operate the existing Māhinerangi Wind Farm near Eldorado Track, approximately 50 kilometres west of Dunedin and 5 kilometres north of Lake Māhinerangi.

Approval has taken four and a half months since the independent expert panel commenced.

“The approved Stage 2 development, known as Puke Kapo Hau, will expand the existing wind farm, which has been operating since 2011,” Mr Bishop says.

“The project will involve the construction and operation of approximately 44 additional wind turbines, a new 110kV transmission line, a substation, and a 60MW battery energy storage system capable of supplying electricity for up to two hours during periods of peak demand.

“Once complete, the development is expected to have an installed capacity of up to 190MW and generate around 550GWh of electricity each year, enough to power the equivalent of around 68,000 homes.

“The project represents a significant investment in Otago and will contribute to the region’s economic growth while supporting New Zealand’s transition to a more secure and sustainable energy future,” Mr Jones says.

“Fast-tracking major infrastructure projects helps unlock investment, supports regional development, and creates opportunities for local communities while delivering the infrastructure New Zealand needs.”

Mr Brown says the Government’s goal is abundant, affordable and reliable power for all New Zealanders.

“We are fixing the basics and building the future by taking key actions to increase energy supply and put downward pressure on prices.

“Fast-tracking consenting rules to encourage energy investment, is one of those actions.

“Renewable energy projects like this are critical to strengthening New Zealand’s energy security and supporting a more reliable national electricity system.”
