Grey River (New Zealand) in the context of "Greymouth"

Grey District is a district in the West Coast Region of New Zealand that covers Greymouth, Runanga, Blackball, Cobden, and settlements along the Grey River. It has a land area of 3,474.31 square kilometres (1,341.44 sq mi). The seat of the Grey District Council, the local government authority that administers the district, is at Greymouth, where 59.0% of the district's population live.

The Grey District is on the West Coast of the South Island. It stretches from the south banks of the Punakaiki River in the north, southeast to Mt Anderson, north to The Pinacle, southeast to Craigeburn, in a southeast direction to Mt Barron, southwest to Jacksons and following the Taramakau River to the Tasman Sea.

Runanga is a small town on the West Coast of the South Island of New Zealand. It is located eight kilometres to the northeast of Greymouth, to the north of the Grey River. Barrytown is 21 kilometres (13 mi) further north. State Highway 6 and the Rapahoe Branch railway run through the town. Runanga was formerly a railway junction, with the steep Rewanui Branch diverging from the Rapahoe line until closure in 1985.

The town's origins can be traced back to European colonisation in the late 19th century, when large numbers of settlers came to work the local coal fields. The town's name is Māori for "meeting place". Coal mining is still the main employer of the town.

Cobden is a suburb to the north of Greymouth on the West Coast of New Zealand. The Grey River separates Cobden from the rest of Greymouth. To the north is the Rapahoe Range, also called the Twelve Apostles Range. State Highway 6 skirts the south-eastern edge of Cobden.

During the period, 1853 to 1876, Cobden was administrated as part of the Nelson Province.

The Buller River (Māori: Kawatiri) is a river in the South Island of New Zealand. The Buller has the highest flow of any river in the country during floods, though it is only the 13th longest river; it runs for 177 km (110 mi) from Lake Rotoiti through the Buller Gorge and into the Tasman Sea near the town of Westport. A saddle at 710 m (2,330 ft) separates the Buller from the Motupiko River and that is divided from the Wairau River by a 695 m (2,280 ft) saddle, both aligned along the Alpine Fault, as is the top of the Buller valley.

Within the Buller Gorge and downstream from the Deepdale River joining, the Buller crosses from Tasman District into Buller District. The Paparoa Range separates the Buller River from the Grey River. A number of flora and fauna are found in the Buller catchment, many of these extending onto the slopes of the Paparoa Range.
