The West Coast is one of the administrative regions of New Zealand, on the west coast of the South Island, one of the more remote and most sparsely populated areas of the country. It includes three districts: Buller, Grey and Westland. The principal towns are Westport, Greymouth and Hokitika.
The region reaches from Kahurangi Point in the north to Awarua Point in the south, a distance of 600 km. To the west is the Tasman Sea (which like the Southern Ocean can be very rough, with four-metre swells common), and to the east are the Southern Alps. Much of the land is rugged, with a coastal plain where much of the population resides.
The land is very scenic, with wild coastlines, mountains and a very high proportion of native bush, much of it native temperate rain forest. It is the only part of New Zealand where significant tracts of lowland forest remain: elsewhere, for instance on the Canterbury Plains and in the Firth of Thames, they have been almost completely destroyed for settlement and agriculture. Scenic areas include the Haast Pass, Fox and Franz Josef Glaciers, the Pancake Rocks at Punakaiki and the Heaphy Track.
The region has a very high rainfall due to the prevailing northwesterly wind pattern and the location of the Southern Alps, which give rise to heavy orographic precipitation. The rain shadow effect is responsible for the relatively arid climate of the Canterbury Plains on the other side of the Southern Alps.
The region's area is 23,000 km². It is divided into the three districts of Buller, Grey and Westland.
