Keown said the wind had pushed the fire into some “light fuels” which had “created a lot of smoke, which has been pushed through to Amberley and at times to Waipara itself.”
Winds were expected to reach more than 100km/h on Tuesday.
Keown said while the fire was burning well away from properties, an evacuation plan was in place if needed.
“Crews will closely monitor the fire ground overnight. Multiple crews, helicopters and heavy machinery will be on site ready to continue containment efforts from the morning.”
All outdoor fires have been banned in Canterbury until next Monday due to warm, windy conditions.
Fire and Emergency declared a prohibited fire season for the Canterbury District.
It said all previously granted fire permits were no longer valid.
