The Taihiki River is a river of the Auckland Region of New Zealand's North Island. It flows generally northeast from its sources north of Patumahoe to reach the Waiuku River shortly before the latter's outflow into the Manukau Harbour. As with the Waiuku River, much of the Taihiki's length is as a wide silty estuary.
