In December 2024 we decided to move ahead with construction of the Kaiwaikawe Wind Farm near Dargaville in Northland. The wind farm will connect to Northpower’s substation near Dargaville, and then on to the national grid at Maungatapere. 

We are adding 36 new turbines to the Kaiwera Downs Wind Farm near Gore in Southland.
This $486 million investment will increase the wind farm’s total capacity from 43MW to a total of 198MW - making it the second largest wind farm in New Zealand. We’re adding enough new electricity to power the equivalent of about 73,000 homes once we reach full generation - expected by the end of the 2026 calendar year.

Kaiwera Downs I Windfarm opens a year on from groundbreaking.

We are adding a fifth generating unit at our Ngā Tamariki geothermal station, increasing generation by ~390 Gwh p.a the equivalent of additional ~55,000 households.

At Mercury we want to do what’s right, and we have a genuine focus on the long term. This drives the way we do business and how we work with others.
