Fire crews today responded to a blaze on a ship in the Napier Port which saw thick black smoke billow into the surrounding area.
Fire and Emergency New Zealand said they were called to the blaze at 10.45am. It has since been brought under control.
"Fire crews are continuing to cool down the ship. We are working with the ship’s Captain and Engineer," Fire and Emergency New Zealand said in a statement this afternoon.
Earlier, they said there were 11 fire crews battling the fire at 4 Wharf.
"People are asked to please keep away from the area to let emergency services work," Fire and Emergency said.
"There is a lot of smoke around. If you are affected, please close any windows. Contact Healthline if you need medical advice."
Napier Port say in a statement crew from the ship are within their 14 days Covid-19 isolation and have been transferred to another separate facility on port.
They say everyone is safe and accounted for.
Medical Officer of Health Dr Nick Jones says the crew, who had come from China, had been at sea for 17 days so were low risk.
They would be tested today as a precaution.
Explosions could be heard coming from the ship as 1 NEWS' Sean Hogan delivered his midday report.
A resident told 1 NEWS he heard the original loud explosion then rushed outside to look.
"It smells like fireworks and sulphur," he said, donning a face mask due to health reasons.
The Ahuriri township has been evacuated due to fumes heading its way.
Meanwhile, a port worker on another boat at the time told 1 NEWS she was worried about her boat, and a man from a dried food company watched on as the ship went up in smoke with their $5 million freezer on board.
