Almost 300 properties are still without power after gale-force winds caused damage to power lines.
Areas of the North Island were cut off on Monday after strong winds caused damage to Powerco's electricity network.
On Tuesday afternoon, the Powerco website showed 299 properties were still without power - almost a day after the original reports of outages.
Te Puke, Taihape, Wanganui and Halcombe all have properties with power outages. The issues range from trees which have fallen on lines to problems with defective equipment caused by high winds.
Most of the properties are not expected to have power again until Tuesday evening - although restoration times are estimated so it could be longer.
Powerco network operations manager Phil Marsh told RNZ on Monday they were expecting wind, but not as strong as it was.
Marsh said lines were down with several cases of fallen trees and foliage due to the gales.
"We have contractors in the field but lines should still be treated as live at all times."
He said repair works would continue into the night, attempting to reconnect as many people as possible.
On Monday around 4000 properties were affected.
