The cause of the outage was a tree falling on power lines due to the high winds.
“Due to the high wind and trees continuing to fall in the work area it is not safe to make repairs until the wind subsides, so the power will remain off for these customers until at least tomorrow,” the Powerco spokesperson said.
“We apologise for the inconvenience this causes.”
Falling trees were a constant threat to the network, Powerco said.
Anyone who came across downed lines should keep themselves, their children and livestock well away, and once safe, call 111.
Powerco could also be contacted on 0800 27 27 27, its 24/7 emergency number.
