Mahinerangi Wind Farm Stage 2 (Puke Kapo Hau)
Mercury NZ · Otago
Stage 2 expansion of the Mahinerangi wind farm west of Dunedin (Stage 1, 36MW, commissioned 2011), gifted the name Puke Kapo Hau. Up to 44 modern turbines (down from an earlier 100-turbine consent). In fast-track consenting — the expert panel issued a draft decision in June 2026 — and still subject to Mercury board approval before construction. Estimated ~$550m (indicative).
