West Coast Power Outages

New Zealand has no open live feed, so the quickest way to check West Coast is the official outage map from Westpower and Buller Electricity.

Westpower serves most of the West Coast, and Buller Electricity, the smallest lines company in the country with about 5,000 connections, serves the Buller area. Buller Electricity has no outage map and posts unplanned updates on Facebook. One defective-equipment fault on 29 December 2025 interrupted about 4,970 connections, nearly its whole network, for three hours, based on Commerce Commission records. Vegetation was Westpower's largest unplanned cause in the year to March 2026.
