The Arapawa pig is a feral breed of domestic pig found on Arapaoa Island in the Marlborough Sounds, New Zealand. Although there are suggestions that the animals are descendants of pigs introduced to the area by James Cook in 1773 and 1777, they apparently derive from Oxford Sandy and Black stock brought to the island by whalers of the Te Awaiti whaling station established in 1827 by John Guard. They are known to have inhabited the island since 1839. In 1998 four piglets were removed from the island and have since bred successfully.
