Waitahaia River
The Waitahaia River is a river in the Waiapu Valley of the Gisborne District of New Zealand's North Island. It flows northeast from Ruatahunga Stream, which originates at the southern end of the Raukūmara Range, to reach the Mata River west of Te Puia Springs. Brown trout, a European species of fish, was introduced into New Zealand for fishing in the late 1860s.
