The tanker Awanuia (R) carries out operations to pump oil from the stricken container ship Rena, about 14 nautical miles (22 km) from Tauranga, on the east coast of New Zealand's North Island in this October 17, 2011 file photo, 13 days after it struck the Astrolabe Reef. The captain and the navigation officer of Rena, which smashed into a reef off a popular New Zealand holiday spot, were jailed on May 25, 2012 for causing the country's worst environmental disaster in decades. The two men, captain Mauro Balomaga and navigation officer Leonil Relon, both Filipino nationals, were jailed for seven months. They had faced maximum terms of seven years imprisonment.
