South Taranaki Offshore Wind Project
Taranaki Offshore Partnership (CIP / NZ Super Fund) · Taranaki
A proposed ~900MW fixed-bottom offshore wind farm in the South Taranaki Bight (~230 km²) by the Taranaki Offshore Partnership, a joint venture of Copenhagen Infrastructure Partners and the NZ Super Fund, enough to power about 430,000 homes, with scope to expand toward 2GW later. The $5b shown is the figure reported for the plan; the partners have separately been reported as committing about US$3b, and no final cost is settled. A final investment decision is expected around 2030-31, and the project depends on New Zealand's new offshore-wind permitting regime.
Data current as at 13 Jun 2026, when the pipeline was last checked against its source.
