An investigation has been launched into an incident aboard a logging ship in Napier Port on Monday night which resulted in six workers being taken to hospital with carbon monoxide poisoning.
While four of the workers were discharged after initial treatment two, a man in his early 20s and one in his late 30s, remained in hospital in a general ward overnight and were eventually discharged this afternoon.
The incident happened about 8pm while the crews were at work on the log ship Nord Yilan.
A fire service spokesman said the turbo unit on the engine blew and billowed exhaust fumes, causing the workers in the hold to be affected.
Other port workers were able to remove the digger from the hold before the fire service arrived.
