Mangapai River
The Mangapai River is a river of the Northland Region of New Zealand's North Island. It is perhaps better described as a silty arm of Whangārei Harbour, located 10 kilometres (6 mi) due south of Whangārei. Its average width is some 4 metres (13 ft), but the silty nature of its course means that the stream itself is far narrower.
The New Zealand Ministry for Culture and Heritage gives a translation of "good stream" for Mangapai.
