The Hinatua River is a small river in the Westland District of New Zealand's South Island. Its headwaters are on Mount Hercules, near State Highway 6 as it runs between Harihari and Te Taho. The Hinatua River then flows in a general northerly direction, passing just to the east of the Saltwater Lagoon before flowing close to the Tasman Sea coastline before joining the Poerua River at its rivermouth.
