Two houses have been evacuated due to a fire in the Canterbury high country, and those displaced residents will have to stay away from their homes overnight.
A further two houses threatened by the 50-hectare blaze at Lake Pukaki were already vacant and did not need to be evacuated, a spokeswoman for Fire and Emergency New Zealand said.
Fire crews from Twizel, Lake Tekapo and Ōmarama responded to the blaze after being called out about 2.30pm.
Firefighters have since brought the fire under control, but had not managed to contain it, the spokeswoman said.
Two helicopters which fought the fire today have been grounded, and one is planned to return at first light tomorrow.
