Tasman Bay

Tasman Bay, originally known in English as Blind 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 of coastline and is 70 kilometres 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. Arrow Rock is situated off the coast of Nelson.
