Hundreds of homes in the North Island have spent a fourth night without power as lines crews work to repair damaged caused by Cyclone Cook.
Contractors have been out since the storm tore through the Bay of Plenty, Hawke's Bay and parts of the East Coast on Thursday, but have struggled to reconnect small pockets of mainly rural homes.
About 100 customers were still cut off in the East Coast region on Sunday evening, with contractors struggling to access damaged lines and trees having caused serious damage to overhead poles.
"These challenges are hindering the progress of our restoration crews. They'll be back out again [on Monday], trying to get your power back up and running as soon as they can," Eastland Group said.
In the Bay of Plenty residents of about a half dozen roads spent another night in the dark on Sunday, with Horizon Networks warning more rain forecast in the area in coming days could cause further outages or delay repairs.
Unison also reports about 100 properties spread across the Hastings and about 50 in Napier are also still having problems, with many expected to be reconnected by Monday afternoon.
