More than 500 houses in the Hastings district were without power on Thursday after high winds caused a tree branch to make contact with a power line.
While power has been restored in the majority of the houses, there were still 84 Unison customers affected at 3.30pm.
A Unison spokesman said the unplanned outage occurred after a tree branch came into contact with power lines on St Georges Rd, Hastings, about 2.29pm on Thursday.
A total of 548 Unison customers were affected as a result.
Houses on St Georges Rd, Grasmere Ave and Farmlet Rd remained without power as at 3.30pm, but were set to be restored by 4.30pm.
