More than 350 tonnes of oil has leaked into the sea around New Zealand from a ship that ran aground, according to government officials.
The vessel, which struck a reef, has created the country's worst maritime environmental disaster, the New Zealand Environment Minister said.
The Rena is stuck 12 nautical miles off the coast of the North Island at Tauranga. The hull is cracked, which means that the ship could disintegrate at any time.
Authorities have told residents to stay away from the shore and to avoid touching the oil as it is believed to be toxic.
Animals are being washed up on the shore covered in oil. More than 1,000 birds are believed to have died.
