Orion is progressively restoring power to the Canterbury homes left in the dark after wild weather lashed the region earlier this evening.
Power has been restored to about 3000 homes and about 1100 are still without electricity.
Orion said wild weather had caused about eleven separate outages across the region and some people will need to be prepared to be without power until the morning.
Power was earlier cut to at least 4084 households across Christchurch and Banks Peninsula, with Orion Energy saying 1000 homes were experiencing outages in Halswell, Hornby, Islington, Prebbleton and Templeton.
Homes in Pigeon Bay, Akaroa and Barrys Bay were also affected.
Late this afternoon, a sudden heavy downpour caused flooding on multiple roads around Christchurch.
Motorists were urged to take extra care.
The worst of the weather was forecast to blow over early this evening.
