It measures about across and about from north to south. The sea was named after the Dutch explorer Abel Janszoon Tasman, who was the first recorded European to encounter New Zealand and Tasmania. The British explorer Captain James Cook later extensively navigated the Tasman Sea in the 1770s as part of his first voyage of exploration. - The Paparoa Range is a mountain range in the West Coast region of New Zealand's South Island. It is located along the coast between the Buller and Grey Rivers, with the Inangahua River to the east. Some of the range is protected as the Paparoa National Park. Within this park, the 1995 Cave Creek disaster occurred. - Paparoa National Park is on the west coast of the South Island of New Zealand. - A mountain range (also mountain barrier, belt, or system) is a geographic area containing numerous geologically related mountains. A mountain system or system of mountain ranges, sometimes is used to combine several geological features that are geographically (regionally) related. On Earth, most significant mountain ranges are the result of plate tectonics, though mountain ranges are formed by a range of processes, are found on many planetary mass objects in the Solar System and are likely a feature of most terrestrial planets. - Captain James Cook (7 November 172814 February 1779) was a British explorer, navigator, cartographer, and captain in the Royal Navy. Cook made detailed maps of Newfoundland prior to making three voyages to the Pacific Ocean, during which he achieved the first recorded European contact with the eastern coastline of Australia and the Hawaiian Islands, and the first recorded circumnavigation of New Zealand. - The Cave Creek disaster occurred on 28 April 1995 when a scenic viewing platform in Paparoa National Park, New Zealand, collapsed, resulting in the deaths of 14 people. The victims, 13 of whom were university students, fell onto rocks below. The tragedy resulted in wide criticism of the government and its policies towards funding and management of the conservation estate. Denis Marshall, New Zealand's Minister of Conservation, eventually resigned, after the Commission of Inquiry's report came out. It also resulted in major changes to procedures used by the New Zealand Department of Conservation after it was revealed that serious systemic failures had led to the building of the unstable platform. Eventual changes in New Zealand Law, following a change of government, allowed for government departments to be held criminally liable for inadequate building practices, in the same way as non-government organisations. - The South Island or Te Waipounamu ("Mori") is the larger of the two major islands of New Zealand, the other being the smaller but more populous North Island.

The country geographically comprises two main landmassesthat of the North Island, or Te Ika-a-Mui, and the South Island, or Te Waipounamuand numerous smaller islands. New Zealand is situated some east of Australia across the Tasman Sea and roughly south of the Pacific island areas of New Caledonia, Fiji, and Tonga. Because of its remoteness, it was one of the last lands to be settled by humans. During its long period of isolation, New Zealand developed a distinct biodiversity of animal, fungal and plant life. The country's varied topography and its sharp mountain peaks, such as the Southern Alps, owe much to the tectonic uplift of land and volcanic eruptions. New Zealand's capital city is Wellington, while its most populous city is Auckland. What is the relationship between 'four mile river' and 'west coast region'?
