Waingawa River
The Waingawa River is a river of the Greater Wellington Region of New Zealand's North Island and a major tributary of the Ruamahanga River.
Its origins are close to The Mitre, the highest peak of the Tararua Range. Once out of the ranges it flows in a straight line southeast across the Wairarapa Valley to join the Ruamahanga River at Te Whiti by Wardell's Bridge.
The Waingawa River is the southwestern boundary of the town of Masterton.
Masterton's water is piped from the Waingawa through a Masterton District Council treatment plant on the river about 10 kilometres west of the town.
