Tasman Bay

Tasman Bay is a large V-shaped bay at the north end of New Zealand's South Island. Located in the centre of the island's northern coast, it stretches along 120 kilometres (75 miles) of coastline and is 70 kilometres (43 miles) across at its widest point. It is an arm of the Tasman Sea, lying on the western approach to Cook Strait.

At the bay's western extremity, the land around the bay is rough and densely forested. Separation Point, the westernmost point of the bay, is located in Abel Tasman National Park and separates Tasman Bay from its smaller neighbour, Golden Bay. To the east, the land is also steep, with the westernmost points of sea-drowned valleys of the Marlborough Sounds. D'Urville Island sits to the northeast of Tasman Bay's easternmost point.

The land between these two extremes is more gently rolling, and also includes the coastal plains around the mouth of the Waimea River at the bay's southernmost point. Other rivers entering the sea along the coast of the bay include the Riwaka, the Motueka and Serpentine Rivers. The long low form of Rabbit Island is located close to the bay's south coast. Tasman Bay contains the rare rock formation known as the Boulder Bank.

The fertile land around the centre of the bay's coast is extensively cultivated with such crops as olives , grapes, hops, and fruit. Tobacco used to be grown and there is a tobacco museum in Motueka It is also the most densely populated part of the South Island's north coast, and several towns and the city of Nelson are all located close to the shore. These towns include Motueka, Riwaka, and Richmond.
