A field crew was dispatched this morning to make repairs and houses should be reconnected by midday Wednesday, Powerco said.
A further 39 homes lost power at 10:34pm Tuesday night in the Brunswick area.
A field crew was dispatched to fix the outage, but Powerco said they were unable to reach the site due to a slip across the road.
The field crew would return Wednesday morning once access to the road was restored, and Powerco said the homes should be restored at around 11:30am Wednesday morning.
On Papaiti Rd 101 homes lost power at 1:52am on Wednesday morning after trees brought down powerlines.
Power was restored to those houses at about 7am Wednesday morning.
