A salvage expert said when it comes to the Manawanui wreck "anything is do able with enough money." Up to 200,000 litres of fuel has leaked into the sea when the ship sank off the southern coast of Upolu in Samoa just over a week ago. It has 950 tonnes in main tanks which are still believed to be intact. Last week, fishers in the area were told not to take seafood and a local local tour operator said sharks are now circling popular surf spots because of food coming out of shipping containers from the Manawanui. The navy said the salvaging of HMNZS Manawanui cannot be rushed and it is a complex operation that will take sometime. Deep Dive Division founder and New Zealand samoan Tua Karalus, who worked on the Rena salvage operation for two years spoke to Lisa Owen.
