a seaport of New Zealand, the principal port on the west coast of South Island, in Grey county. Pop. (1906) 45 6 9. It stands on the small estuary of the Grey or Mawhera river, has a good harbour, and railway communication with Hokitika, Reef ton, &c., while the construction of a line to connect with Christchurch and Nelson was begun in 1887. The district is both auriferous and coal-bearing. Gold-dredging is a rich industry, and the coal-mines have attendant industries in coke, bricks and fire-clay. The timber trade is also well developed. The neighbouring scenery is picturesque, especially among the hills surrounding Lake Brunner (15 m. S.E.).
