Two people had minor smoke inhalation issues due to a fire at Waverley's Rainbow Dairy on Monday morning.
The alarm went up at 11.13am and Whanganui, Patea and Waverley fire crews attended, Waverley chief fire officer Alan Hickford said.
They were able to douse the fire quickly, but the interior of the building received some smoke damage. An ambulance also attended, but the two people who inhaled smoke didn't need to be taken to hospital.
Waverley firefighters finished the job and were back at their station having a debrief by noon.
Mr Hickford said the fire started in a clothes dryer.
