Mr Fleetwood said that if it had been a New Zealand crew they would not have stayed on the vessel for the six days since the Rena struck Astrolabe Reef off Tauranga.
"If that was a New Zealand crew they would have been off the ship straight away. If that was an Australian crew they would have been off and done. They're Filipinos, and what I believe is they're treating them with contempt and telling them 'just stay there and do your job'. I've called for Maritime New Zealand to release all their reports so we can know who made all these decisions."
Maritime NZ said the crew would go back onto the ship once it was deemed safe to do so, but Mr Fleetwood doubted this would ever be the case.
Mr Fleetwood said he had been calling on the Government to buy an emergency oil spill response vessel "for years" but to no avail.
"Now we're caught with our pants down."
