Outages

There are two types of power outages: planned and unplanned.

If a power outage is planned, your chosen electricity retailer will advise you ahead of time and provide the date and time this will occur. Make sure to note this date down so you are prepared for the outage.

If your power goes off and it is not a planned outage, check the MainPower outage map to see if your area is affected by an unplanned outage.

If you have any concerns or would like to advise us of a hazard, call us on 0800 30 90 80.

  • Planned outages are when we need to do planned maintenance on our network. These are scheduled ahead of time so that work can be completed safely.

  • Unplanned outages can be caused by anything from cars hitting our power poles, debris flying into our overhead lines, or people hitting our underground cables with digging equipment. Wind storms or earthquakes are also likely to cause unplanned outages.

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.
