After 20 years, a hydro dam gets consented

The Government announced:

A fast-tracked renewable energy project on the West Coast will strengthen regional electricity supply and improve resilience, Infrastructure Minister Chris Bishop and Regional Development Minister Shane Jones say.

In August 2025, Westpower Limited lodged a substantive application to build and operate a 23MW hydro scheme in the Waitaha Valley, about 38km south of Hokitika. The project includes a weir and a 1.5km tunnel to a two-turbine powerhouse.

“The Waitaha Hydro project has taken around 20 years to progress. Westpower Limited sought Department of Conservation concessions in 2014. Following a publicly notified process and a hearing in 2016, the Minister for the Environment declined the application in 2019,” says Mr Bishop.

“In 2022, Westpower applied to DOC seeking that the 2019 decision be reconsidered. That reconsideration process was suspended when the project obtained a listing in the FTAA and was subsequently withdrawn by Westpower.

“Fast-track meant this project received all the necessary approvals in around five months from the appointment of an expert panel.”

Fascinating how all the environmental groups say we need more renewable energy, but they always oppose every renewable energy project, and decry the fast track law that has managed to get them consented.

“Westpower estimates the scheme will generate enough renewable electricity to power around 12,000 homes each year and prevent up to 129,000 tonnes of CO₂ emissions annually. This is about the same as taking roughly 69,000 cars off the road annually,” Mr Jones says.

“The West Coast faces some of the highest electricity costs in New Zealand, largely due to its distance from major generation sources and dependence on a 550km-long transmission line. Increasing local generation is expected to help ease these pressures over time.

“The scheme could also contribute to New Zealand’s wider energy system by helping to manage dry-year risks affecting hydro generation elsewhere in the country.”

“Construction is expected to deliver significant economic benefits to the region, with total investment estimated between $160m and $200m. Around 71 full-time equivalent jobs will be created over the three-year construction period,” Mr Bishop says.

The West Coast is often wet, when nowhere else is. It will help with supply, reduce emissions, and create jobs.
