A fire at a large Green Island commercial shed is under control, but work to completely put it out continues tonight.
A witness heard three loud booms before the shed went up in flames this afternoon, which sent smoke all over the area.
Multiple fire crews were called to the blaze in Bush Rd, near the turnoff to Tunnel Beach.
"It went boom, boom, boom," the witness who raised the alarm, said.
By 7pm, a Fire and Emergency NZ spokesman said the blaze was controlled, but it would take longer to completely extinguish it.
The first were at the scene by 3.20pm - there was now crews from the Roslyn, St Kilda, Dunedin, Wakari, Lookout Point, Mosgiel and Portobello stations.
Four trucks, two water tankers, one rural appliance, a command centre and a few support vehicles were in attendance.
Heavy machinery was used to remove parts of the building, helping crews to extinguish flames.
The shed appears to be on a lifestyle property.
