The fire on board a Sanford fishing boat at Auckland's waterfront is out.
Around eight fire appliances have turned up to deal with the small fire onboard the ship.
It's believed to have started when welding was being carried out on board, but was put out by the crew with a fire extinguisher.
All 50 staff on board were evacuated but should be back on the boat within the hour.
Meanwhile, five fire crews are battling a "significant" blaze in central Taupo.
