Firefighters douse blaze at warehouse in Penrose, Auckland
A Penrose, Auckland sign writing business has been extensively damaged by fire.
More than a dozen fire crews were called to the Great South Rd blaze about 6.15pm on Monday.
Mt Wellington Fire Brigade Senior Station Office Bob Morrison said crews "got in pretty quickly" to contain and extinguish the fire at Design Signs.
There had been "extensive damage to printing equipment" in the main work area of the building.
"A fair bit of heavy smoke" has also affected a neighbouring business, he said.
A fire investigation team will look into the cause.
Traffic was diverted from the area for a short time.
