Waitoa River

The Waitoa River is a major river of the Waikato Region of New Zealand's North Island. It flows initially northeast from its origins at Piarere, before veering north through the Hinuera Gap and across the Hinuera Plains to pass to the west of Matamata, Walton and Waharoa before running through the settlement of Waitoa and reaching the southern edge of the Hauraki Plains. It converges with the Piako River in the Kopuatai Peat Dome wetland, approximately 15 kilometres north of Morrinsville.
