In contrast however, Mr Heath said the network could not cope with a car which struck a pole near Ohaeawai on Tuesday morning and knocked out the power to 460 customers.
The affected area included part of Okaihau, Umawera, Waihou Valley, Mangamuka and even Peria on the other side of the Mangamuka Ranges, Horeke in South Hokianga, and a large swathe of North Hokianga including Broadwood, Kohukohu, Motukiore and Panguru.
The accident, just after 7am, left the broken pole resting on top of the Toyota Corolla and live high-voltage lines hanging at head height over one lane of State Highway 1.
Okaihau fire chief Andrew Graham said the driver, a young man, was uninjured but stayed in the car for about 20 minutes until firefighters could assure him the lines were no longer live.
Police are investigating the cause of the crash.
