Ulva Island is an island sanctuary in Paterson Inlet, free of introduced animal pests, and with full public access. It has an important role to play in the conservation of threatened species, as well as providing a great opportunity to experience New Zealand ecology.br/br/Rugged and bush-clad, Stewart Island is New Zealand#213;s third largest island, of which over 80 per cent is set aside as the Rakiura National Park. Back in 1770, Captain James Cook's crew were the first Europeans to sight the island but they mapped it as a cape connected to the South Island. Separated from the South Island by Foveaux Strait, the only town is Oban, on Halfmoon Bay. Fishing has been, historically, the most important element of the economy of Stewart Island/Rakiura, and while it remains important, tourism has become the main source of income for islanders.
