Firefighters are battling a fire in a two-storey building next on Greenlane West next to the ASB Show Grounds.
No one is trapped and the fire, on the first floor of the building, is unlikely to spread.
A Fire Service spokesman said the blaze was "quite visible" and there had been multiple 111 calls.
Part of Greenlane West has been closed off while firefighters extinguish the fire.
