Nearly 10,000 people are without power in Buller, after the electricity to the district was cut as a storm lashes the South Island.
Buller Electricity Limited said the main line into Westport was off: “This means [the] whole district is without power”.
The company said its staff were on standby and warned people to treat all wires as live.
Much of the southern part of the country is getting snow, and forecast strong winds of up to 130km/h.
