Two divers working on the salvage of the Rena have been fired after helping themselves to wine inside one of the ship's containers.
Svitzer Salvage says the pair - believed to be Dutch - were "dismissed immediately" as soon as it learned wine had been stolen.
The divers were among a team of contractors who earn up to $2300 a day in often dangerous conditions.
Svitzer spokesman Matthew Watson could not say last night how much wine was taken - or how much was drunk - but believed the quantity was small.
"My understanding is that it wasn't a great amount. It's also not clear if the wine was returned or replaced, but either way, it will be returned or replaced. The bottom line is that what has happened is totally unacceptable."
