Vector said 130 customers in Grey Lynn will remain without power until the repairs have been made.
Another outage, covering a large area of Newmarket and Grafton, was reported to Vector – Auckland’s electricity distributor – at 2.58pm.
A Vector spokesperson told the Herald crews were working in Grafton to repairan underground cable fault that occurred earlier this afternoon.
“We will get the power back on as quickly as we can. We understand the inconvenience of a power outage on the eve of a long weekend. Our crews are working hard to restore power for those customers impacted.”
Shortly before 8pm the spokesperson said power had been restored to all customers in Newmarket.
About 3000 people were without water on Thursday evening and about 15,000 had low pressure.
Watercare chief operations officer Mark Bourne said its contractors completed the fix at 1.30am.
The affected suburbs were Henderson, Henderson Valley, Glen Eden, Kaurilands, Sunnyvale and Ōrātia. The outage also impacted parts of Glendene, Konini, north Titirangi, Kelston and Waitākere.
Bourne warned some of the water might appear milky or discoloured, but testing this morning had shown it was safe to drink.
