river, South Island, New Zealand. It rises in the Eyre Mountains south of Wakatipu Lake and flows south past Gore and Mataura to enter the Pacific Ocean at Foveaux Strait, 20 miles (32 km) east of Bluff, after a course of 149 mi (240 km). Together with the Oreti and Aparima rivers, the Mataura has created the Murihiku (Southland) Plain and drains an area of 281 square miles (728 square km). The river derives its name from a Maori term meaning “reddish, glowing face,” referring to the red glow of the river surface when swamp water, coloured red by iron oxide, drains into it. The Mataura had a whaling station at its mouth in the 1830s.
