Mount Tasman (Horokoau in Māori) is New Zealand's second highest mountain, rising to a height of 3,497 metres (11,473 ft). It is located in the Southern Alps of the South Island, four kilometres to the north of its larger neighbour, Aoraki / Mount Cook. Unlike Aoraki / Mount Cook, Mount Tasman sits on the South Island's Main Divide, on the border between Aoraki/Mount Cook National Park and Westland Tai Poutini National Park. It is the highest point in Westland District.
