Greenpeace New Zealand activists storm on-board a New Zealand Government ship in Wellington and lock themselves to it, after discovering it has been searching for oil. Greenpeace says the NIWA taxpayer-funded climate and ocean research boat, Tangaroa, has been refitted at a cost of $24 million for oil and gas exploration, and is now surveying for oil on the East Coast of the North Island on behalf of petroleum giants Statoil and Chevron.
