Earlier on Saturday night, Northpower asked people to conserve electricity while the outage persisted due to the large load on the network after some areas were switched to other supplies.
“With the switching of power from other parts of the network, some areas are now heavily loaded,” communications manager Rachel Wansbone said earlier.
The company asked customers in the Whangārei city, Keingston, Whau Valley and Tikipunga areas to conserve power in order to keep their electricity connected.
According to Northpower, the outage earlier affected greater Whangārei Central, Maunu, Tikipunga, Onerahi.
It included the rural areas Ngunguru, Parua Bay, Kauri, Hikurangi, Hukerunui, and all East Coast locations from Whangārei Heads to Bland Bay.
