The Te Arai River is a river of the Gisborne Region of New Zealand's North Island. It flows generally north from its origins in rough hill country 20 kilometres (12 mi) north of Nuhaka before veering northeast past the township of Manutuke to reach the Waipaoa River five kilometres from the latter's outflow into Poverty Bay.
