Aerial power line inspections on the MainPower network

MainPower are carrying out aerial power line inspections on the electricity network between 24th May and mid-June.

The inspections will be completed using a camera mounted on a helicopter flying 500-1000ft above power lines. This is a normal height at which aircraft, such as Westpac rescue helicopters, operate at.

The helicopter will be flying continuously at a moderate speed and hovering is not expected. Some turning or circling may be necessary in some areas, to fully capture the powerline imagery we require.

It will only be in your area for a short time as it moves across the network.Electricity supply will not be affected during the inspections.

The inspections are weather permitting, so at this stage, we cannot give specific times the aircraft will be near properties.

If you would like more information, please contact our inspection provider, Aethon Aerial – Project Manager Chris Demuth | cdemuth@aethonaerial.com

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.
