Raucous couch-burning students in Dunedin have accidentally set a house on fire during their partying, narrowly avoiding tragedy, police say.
Officer were called to a large party on Castle Street at midnight, where several hundred party-goers at two houses were spilling on to the road.
While containing the crowd, attending officers saw flames from a burning couch had spread to another home's weatherboards.
Police said the occupants were woken and evacuated, and the officers attempted to extinguish the flames before the fire service arrived to put the fire out.
It had begun to take hold within the exterior wall just as it was extinguished, police said. There was damage to the weatherboards.
