"Restoration time can differ according to each customer's address, which is why we recommend people utilise the outage centre. The electricity operations centre is continuously remotely redirecting power flows to as many affected households as possible, therefore we can't provide an exact number of customers affected at one point in time."
A smaller emergency power shutdown had also occurred on Salisbury Rd at Birkdale on the North Shore.
This was due to a fault to the lines caused by high winds. Crews are currently on site working to repair the fault. Power has been redirected to most customers in the area but a small number of customers are still without power, the spokeswoman said.
People can keep up to date with restoration work relevant to their specific address through the Vector Outage Centre, available on vector.co.nz/outages
