Southland Power Outages

New Zealand has no open live feed, so the quickest way to check Southland is the official outage map from The Power Company and Electricity Invercargill.

The Power Company serves rural Southland and Electricity Invercargill the city and Bluff, both managed by PowerNet. The 23 October 2025 windstorm broke what PowerNet called the 'backbone' of its Southland network, leaving 17,800 of 38,200 customers out a day later and prompting a state of local emergency. That took The Power Company to 2,690 minutes of interruptions per customer in the year to March 2026, the highest in the country, while Electricity Invercargill recorded 50. Manapōuri, the country's largest hydro station, is in Fiordland.
