The Wairau Bar, or Te Pokohiwi, is a 19-hectare (47-acre) gravel bar formed where the Wairau River meets the sea in Cloudy Bay, Marlborough, north-eastern South Island, New Zealand. It is an important archaeological site, settled by explorers from East Polynesia who arrived in New Zealand about 1280. It is the earliest known human settlement in New Zealand. At the time of the occupation it is believed to have been a low scrub-covered island 2 to 3 metres (7 to 10 ft) high, 1.1 kilometres (0.68 mi) long and 0.4 kilometres (0.25 mi) wide.
