The Mangahauini River is a river of the Gisborne Region of New Zealand's North Island.[1] It flows generally south from its origins southwest of Te Puia Springs, reaching the Pacific Ocean close to the settlement of Tokomaru Bay.

History

Major floods occurred in 1916, 1924,[2] 1950,[3] 1963[4] and the 2022 flood washed away part of the State Highway 35 bridge at Tokomaru Bay,[5] which was last rebuilt in 1966.[6] The new bridge is downstream from its predecessor.[7] The main road runs through the valley for several kilometres, crossing the river three times.[8]
