Greymouth (Māori: Māwhera) is the largest town in the West Coast region in the South Island of New Zealand, and the seat of the Grey District Council. The population of the whole Grey District is 13,600, which accounts for 41% of the West Coast's inhabitants. The Greymouth urban area had an estimated population of 9,870 (June 2014 estimates). The District Council expects growth of 1.5% per year between 2006 and 2016.
The town is located at the mouth of the Grey River, on a narrow coastal plain close to the foot of the Southern Alps. In clear weather, Aoraki/Mount Cook can be clearly seen to the south from near the town. The mouth of the river divides the town into three areas: Blaketown, close to the river's mouth on the south bank; Karoro, to the southeast, separated from Blaketown by a series of small estuarine lakes; and Cobden, formerly a separate town, on the river's north bank.
Greymouth is on State Highway 6, which connects it with Hokitika in the south and Westport in the north. It also stands at the terminus of State Highway 7, which runs through Dobson and Reefton, eventually reaching North Canterbury and its junction with State Highway 1 at Waipara (55 km north of Christchurch) via Lewis Pass. Highway 73 is accessed 20 km south of Greymouth, which is the most direct route to or from Christchurch. The town is also the western terminus of the Midland line from Christchurch. Large coal trains often operate from Greymouth on this line to Christchurch. The famous TranzAlpine train also terminates at Greymouth. The Greymouth Airport is located conveniently only 1.9 km south of the centre of the town.Map
