Emergency services were called to deal with a fire in the mixing room of a concrete supplier in Dunedin this morning.
A Fire and Emergency New Zealand spokeswoman said crews from Willowbank and Dunedin, including a ladder, were called to the blaze at Allied Concrete in Anzac Ave.
The fire was described as "fully involved" on arrival. However, it was now under control and crews were ventilating the premises, she said.
There were no injuries and the extent of any damage caused by the fire was not yet known, she said.
Police were called to the scene to help with traffic control.
