The Tapuaeroa River is a river of the Gisborne Region of New Zealand's North Island. It flows southeast from its sources in the Raukumara Range from the confluence of the Oronui Stream and Mangamauku Stream, joining its waters with those of the Mata River close to the town of Ruatoria, the resulting flow becoming the Waiapu River.
