Fire crews from across northern Christchurch have been fighting a fire at a sawmill in Belfast overnight.
Emergency services were called at 2.30am to the building fire, Fire and Emergency northern shift manager Bailey Wells said.
On arrival they found a 30m x 30m boiler house well involved in fire.
Four pumps, five tankers and a command unit were sent to the scene, with crews from Redwood, Ilam, Spencerville, Anzac, Christchurch City, Woodend, Rangiora, Pines Beach and Wigram attending.
