Mt Munro Wind Farm

We’re proposing to build a 20-turbine wind farm at Mt Munro, approximately five kilometres south of Eketāhuna in northern Wairarapa.

The Environment Court has granted consent for our 90MW Mt Munro Wind Farm near Eketāhuna in northern Wairarapa. This will produce around 300GWh of renewable energy each year – enough to supply up to 42,000 average homes.

February 2026

Work continues on the pre-construction stage of the project. This includes undertaking some initial geotechnical investigations and data gathering for the Old Coach Road design upgrade.

We now move into the detailed design phase. In the coming months, we’ll be upgrading some of the farm tracks on site and completing more detailed geotechnical investigations. We continue to work towards a final investment decision by our Board of Directors towards the end of 2026.

Stakeholder Liaison Group

Our first Stakeholder Liaison Group (SLG) was held on 14 February. The group meets at a minimum of every three months and is chaired by an independent facilitator.

You can read more about the meeting in the confirmed minutes below.

Details of the proposed project:

  • Up to 20 wind turbines would be located on three privately owned properties, which would continue to operate as working sheep and beef farms.
  • The turbines would produce around 300 gigawatt hours of renewable energy annually, enough to supply up to 42,000 average homes.
  • The turbines would be spaced in ways that made best use of prevailing wind conditions on the sites and also balance any potential effects.
  • The turbines would have blade diameters of up to 136 metres, a maximum height above ground level to a tip height of up to 160 metres and an approximate capacity of 4.5 megawatts each.
  • Up to 14 turbines would be closely spaced along the site’s main ridgeline envelope area (blue shaded area on map), with two further groups, each up to three turbines, on the lower hills to the northwest of the main ridge.
  • Access to the site for construction and operation would be via Old Coach Road North. Internal wind farm roading would be based on existing farm tracks.
  • The 3.5-kilometre transmission line connecting the wind farm to the national grid would use steel or concrete poles up to 20 metres high. 
  • The substation would be located near the point near where the transmission line connects with Transpower’s 110-kilovolt line, on the corner of Kaiparoro Road and State Highway 2.
