The spokesman acknowledged that work to repair lines damaged earlier this week due to bad weather had been hampered by continued poor weather conditions.
"Lightning strikes and a number of car versus pole accidents around the city have caused new outages overnight and diverted some of our resources from the storm recovery work,'' he said.
There is also a push to reconnect those in more remote parts of the city - particularly around the West Coast and Northwest Coast places including Piha, Riverhead, Kaukapakapa and Bethells Beach.
The spokesman said in those areas, lines had to be repaired section by section. It was difficult for crew members to understand just how damaged a section was until they got to it.
As a result, some of those places or parts of those areas would not have their power back on until mid-next week.
A car crash in Remuera has also brought down power lines.
A Fire and Emergency spokesman said a car had hit a pole on Abbots Way.
Emergency services were called about 11.20pm.
No injuries had been reported and no one was trapped in the vehicle.
Those people still without power were urged to keep an eye on the latest information and updates on which areas crews were working on via the Vector site.
Those who were medically dependent or were in a vulnerable situation are encouraged to get in touch with their electricity provider urgently or to contact emergency services.
Meanwhile, more than 2000 welfare checks have been made across the Auckland region.
Up to 130 people from various agencies - Auckland Emergency Management, the Auckland Council, NZ Defence Force, Land Search and Rescue, Red Cross and the police - were out door-knocking and checking the homes of residents without power.
The checks will continue tomorrow, a statement said.
Community hubs have opened in Massey, Three Kings, Waitakere, Kumeu, Waimauku, Glenfield and Waiatarua for those needing extended welfare support.
All hubs will be open tomorrow from 8am to 4pm and all Auckland Council leisure centres and YMCAs are offering a hot shower for free as well as somewhere to get warm and have a hot cup of tea or coffee.
The hubs are at: Waimauku War Memorial Hall, Kumeu Library, Massey Leisure Centre, Waitakere Domain Hall, Waiatarua Fire Station and the Flicking Convention Centre in Three Kings.
