A cargo ship that caused New Zealand's worst maritime pollution disaster when it ran aground three months ago broke in two in a storm today, raising fears of a fresh environmental crisis.
A team of oil-spill and wildlife specialists has been mobilised as oil again began flowing from the Rena, which has been stuck on Astrolabe Reef off the North Island resort area of Tauranga since 5 October.
Shipping was also being warned to stay away as up to 300 containers were washed from the wreck and salvage workers said there was a strong likelihood the stern section would capsize.
The Rena is now in two pieces which have been forced 20-30m apart after being pounded by waves up to seven metres high.
Maritime New Zealand on-scene commander Alex van Wijngaarden said the National Response Team, which included oil spill response and wildlife experts was preparing for the likelihood of more oil coming ashore.
More than 1,000 tonnes of oil have since been pumped off the ship but there is more on board.
While it posed a risk Environment Minister Nick Smith said it would not be as bad as when the Rena first ran aground.
The Filipino captain and second officer of the Rena have been arrested and face multiple charges over the grounding, including operating a vessel in a manner causing unnecessary danger or risk.
They have also been charged with attempting to pervert the course of justice, which carries a seven-year jail term, amid accusations documents were altered after the grounding.
The two men are on bail but are being housed at a secret location for their own safety because of fears of a public backlash.
