A fire that started in a garage at a Mosgiel property will be investigated, Fire and Emergency New Zealand (Fenz) says.
A Fenz spokesman said crews responded to a fire at a single-storey residential dwelling in Mosgiel about 1.45am on Saturday.
The fire was initially located in a garage but was spreading into the house.
By 3am, crews had managed to suppress the fire, the spokesman said.
Crews from Dunedin, Lookout Point, Mosgiel, Outram, St Kilda and Roslyn all responded to the scene throughout the night.
Some crews remained on the scene until later in the morning conducting hot spots and checking the area was safe.
Fire investigators were looking over the property on Saturday to determine the cause of the fire, the spokesman said.
The cause of the fire would remain unknown until the investigation finished in a couple of weeks.
