A Canterbury home has been destroyed after a fire ripped through land near the Malvern Hills this afternoon.
Selwyn District Council said the large fire had now been contained, but some smaller spot fires were still active in the area of about 60 hectares.
It said one house on Homebush Road had been destroyed, along with six outbuildings, including a hay barn.
Three others were threatened but had escaped any damage. Five people were being helped at an evacuation centre.
Fire Service said a change from strong north-westerly winds to south-west winds was expected later tonight and may help to reduce temperatures and the risk of more fires.
Hot, dry and extremely windy conditions in the region had made things difficult for firefighters.
Four fire appliances are at the fire, with one helicopter and two further helicopters are due to arrive.
Selwyn Rural Fire officer Douglas Marshall told Checkpoint with John Campbell there were 70 firefighters battling the blaze with the use of three helicopters.
Strong winds have spread the fire, which broke out about 5pm.
"It is incredibly windy at the moment and we are stretched in this area.
"We have evacuated about half a dozen homes and we have got an evacuation centre, welfare centre, set up at the Darfield Recreational Centre for those who wish for some sort of support."
Police are asking people to put off travelling west or south west of Darfield.
Strong winds spark fires
Strong winds across the South Island have fanned several other fires, including one near Kaikoura, started by a truck that caught alight.
The fire has closed the highway south of Kekerengu.
Helicopters are working to control the blaze.
Small vegetation fires have also broken out near Ashburton, with one fire in the region earlier this afternoon causing the closure of State Highway 1 and railway tracks near it.
