Work is continuing in the Hawke's Bay, Gisborne, and Whakatane regions to restore power cut in the aftermath of Cyclone Cook.
Line crews facing challenging conditions and less-than-ideal weather are hoping to restore power to the approximately 430 homes still without electricity.
In the Whakatane district, 250 homes remain without power, Horizon energy said in a statement.
"The weather forecast is predicting further rain for the district over the coming days, this may result in further outages and delays in restoring supply across the region due to slips and trees."
Meanwhile in Gisborne, Eastland Network say there are still approximately 100 customers still affected in Tauwhareparae and Hokoroa.
"In both of these areas, we're having significant problems with access, and trees have caused serious damage to overhead poles and lines in a number of places," Eastland Network's Facebook statement read.
In Hawke's Bay, Unison energy said it has restored power to 99 per cent of the households affected by Cyclone Cook.
The are still approximately 274 homes affected, either with no power, no hot water, or partial power restoration.
There are 80 homes still without power, but Unison said it is confident that it can get everyone back up and running today.
