Power has been restored to parts of the North Shore where some 10,000 homes went without today.
People had reported outages at Albany Mall and a number of homes.
A mall spokeswoman confirmed power had gone out temporarily, but it was switched back on after about 10 minutes.
Vector spokeswoman Sandy Hodge said crew were out at a site "progressively" restoring the power.
She wasn't sure what had caused the outage, but said more would be known once crew returned.
