Awanui is an historical river port in the far north of New Zealand, on the banks of the Awanui River just before it flows into Rangaunu Bay. Awanui lies at the south end of the Aupouri Peninsula in the Far North District Council of the Northland Region, approximately 7 km north of Kaitaia. The river port has ceased operation and a recreational wharf is located at Unahi, on the shore of Rangaunu Bay, approximately 3 km north of the township. The traditional name of Awanui was Kaiwaka and Awanui proper refers to the "River at Kaiwaka".
