Inangahua is a small settlement in the northwest of New Zealand's South Island. It consists of three settled areas: Inangahua Junction at the confluence of the Inangahua and Buller Rivers, north of Reefton and southeast of Westport; Inagahua Landing, 10 km further up the Inangahua River; and Inangauhua township, 2 km east of the Junction. Murchison is further east. After the 1968 Inangahua Earthquake, most of the inhabitants left the area or shifted to the township, which is now the population centre and known simply as Inangahua.
