The Grey River / Māwheranui is located in the northwest of the South Island of New Zealand. It rises 12 kilometres southwest of the Lewis Pass in Lake Christabel, one of numerous small lakes on the western side of the Southern Alps, and runs westward for 120 kilometres before draining into the Tasman Sea at Greymouth. Thomas Brunner, who explored the area in the late 1840s, named the river in honour of Sir George Grey, who first served as Governor of New Zealand from 1845 to 1854. The Ngāi Tahu Claims Settlement Act 1998 changed the official name of the river to Grey River / Māwheranui in 1998. The Māori name for the river system and surrounding area is Māwhera, with Māwheranui being distinguished from the northern branch Little Grey River / Māwheraiti.
Lake Christabel is a small lake in the north of New Zealand's South Island. It is located 12 kilometres southwest of the Lewis Pass. The lake is the source of the Grey River, one of the longest rivers on the South Island's West Coast, although its outlet is underground. The lake lies behind a landslide dam, thought to have been created by a prehistoric earthquake. The river runs under the debris for about 200 m (660 ft). A 1976 survey said it was, "one of the very few lakes in New Zealand in a natural, unmodified state". It estimated its depth at over 90 m (300 ft). Galaxias brevipinnis and Anquilla dieffenbachii were the only fish found.
