WEATHER RELATED OUTAGES - updated 12.00pm 29/10/2025

We’re making great progress restoring power across the network. Currently there are 85 customers without power, but we have a large number of crews in multiple locations again today.

We will have a helicopter operating in the Hurunui Mouth area around midday today. The helicopter is a twin engine and is carrying out complex river crossing repairs. It will be travelling low and slow, and it will be quite loud.

Please keep the area clear so our teams can carry out these urgent repairs to restore power to the area.

Estimated restoration times are regularly being uploaded to the Outage Map.

If you have any concerns or questions, please call our customer service team on 0800 30 90 80.

TREAT ALL POWER LINES AS LIVE AT ALL TIMES. Please stay away from any downed lines and report any sighting to us on 0800 30 90 80.

For the most recent updates on outrages, please check our outage map. To report an outage, call 0800 30 90 80.
