Firefighters battled a blaze in a mechanical workshop in West Auckland this evening.
Nine fire units were called to the mechanical workshop and factory in Ranui at 5.23pm.
Fire Service northern communications shift commander Scott Osmond said the fire was in the property's front two units.
He said "multiple deliveries of water''were needed to bring it under control.
It was not believed to be suspicious. There were no reported injuries.
Police blocked vehicle access to the one-way street, said spokesman Senior Sergeant Matt Rogers.
