Tauranga police are investigating a suspicious fire which occurred in Tareha Lane in Te Maunga last night.
The fire was noticed by local residents just after 11pm and a number of fire appliances attended and put out the fire.
As a result of the fire, extensive damage was caused to a wooden deck as well as the side of an administration building on the Tamapahore Marae.
Firefighters said this morning it was possible a discarded cigarette could have started the blaze.
Police detectives and fire investigators from the New Zealand Fire Service have been involved in conducting a scene examination this morning.
