A hanging spray boom from a helicopter which cut through powerlines at Lake Tarawera left more than 700 residents without power today.
Unison power spokesman Danny Gough said the incident happened just after 6.30am where a helicopter came into contact with lines, cutting through them and causing a pole to fall down.
A brief power cut happened in parts of the city, however 760 residents in the Lake Tarawera, Lake Ōkareka, Lynmore and Tumunui areas were without power for about nine hours.
Power was restored about 3.30pm.
Gough said crews had trouble getting to the site for repairs as it happened in a rural area off Tarawera Rd.
