- Source: Clarke River (Westland District)
The Clarke River in Westland District is the southernmost of three rivers thus-named in the South Island of New Zealand.
It is a major tributary of the Haast River, flowing southwest from its source on the slopes of Mount Hooker before joining with the Landsborough River three kilometres before the waters of both flow into the Haast at the point where the latter river turns west towards its outflow into the Tasman Sea.
