Arapaoa Island (formerly spelled Arapawa Island) is an island located in the Marlborough Sounds, at the north east tip of the South Island of New Zealand. The island has a land area of . Queen Charlotte Sound defines its western side, while to the south lies Tory Channel, which is on the sea route between Wellington in the North Island to Picton. Cook Strait's narrowest point is between Arapaoa Island's Perano Head and Cape Terawhiti in the North Island. History According to Māori oral tradition, the island was where the great navigator Kupe killed the octopus Te Wheke-a-Muturangi. It was from a hill on Arapaoa Island in 1770 that Captain James Cook first saw the sea passage from the Pacific Ocean to the Tasman Sea, which was named Cook Strait. This discovery banished the fond notion of geographers that there existed a great southern continent, Terra Australis. A monument at Cook's Lookout was erected in 1970. From the late 1820s until the mid-1960s, Arapaoa Island was a base for whaling in the Sounds. John Guard established a shore station at Te Awaiti in 1827, however initially could only salvage baleen until the station was equipped to process whale oil from 1830 onwards, targeting right whales. Later, the station at Perano Head on the east coast of the island was used to hunt humpback whales from 1911 to 1964 (see Whaling in New Zealand). The houses built by the Perano family are now operated as tourist accommodations. In the 2000s the former whalers from the Perano and Heberley families, who live on Arapawa, joined a Department of Conservation whale spotting programme to assess how the humpback whale population has recovered since the end of whaling. In August 2014, the spelling of the island's name was officially altered from Arapawa to Arapaoa. Aircraft accident The 11,000-volt power lines linking the mainland and Arapaoa Island over Tory Channel was struck by an Air Albatross Cessna 402 commuter aircraft in 1985. The crash was witnessed by many passengers on an inter-island Cook Strait ferry. The ferry immediately stopped to dispatch a rescue lifeboat. Along with the two pilots, one entire family died, and all but a young girl from the other. No bodies were ever found. The sole survivor (Cindy Mosey) was travelling with her family and the other family from Nelson to Wellington to attend a gymnastics competition. The Arapaoa Island crash caused
