In Whangarei and Kaipara, electricity to more than 2500 households was affected over the weekend but all repairs on power lines had been completed by Sunday morning.
Power was cut off to about 2000 homes in Hikurangi, Pataua, Ruakaka, McLeods Bay and Parua Bay on Saturday and 672 Northpower customers south of Ruakaka were affected yesterday.
The outage came after a large tree fell on lines.
Power was restored to most of the affected customers by Saturday evening.
Northpower network services manager Graham Dawson said the way the community had worked with staff to alert the lines company to outages had helped minimise blackout times.
"I have been in the field on Saturday with our lines crews and arborists. They've been exposed to fairly challenging conditions and they've done the job. So far, the Northpower network has held up well," he said.
Mr Dawson said Northpower customers should continue to report the potential cause of power outages on 0800-10-40-40.
Members of the public are still advised to remain clear of downed power lines.
