The Mata River is a river of the East Coast of the North Island of New Zealand. It flows northeast from the slopes of Mount Arowhana in the Raukumara Range to join with the Tapuaeroa River close to the settlement of Ruatoria, in doing so forming the Waiapu River, which reaches the Pacific Ocean near Rangitukia, 10 kilometres (6 mi) south of East Cape.
