The Otamatea is formed by the confluence of the Wairau and Kaiwaka rivers and the North Auckland Line crosses at this point. Almost 300 metres (330 yd) wide at its origin, the river widens to 1.8 kilometres (1.1 mi) by its mouth opposite Tinopai. Several other broad tidal creeks flow into the Otamatea, including Raepare Creek, Awaroa Creek, Takahoa Creek and the Whakaki River on the left bank and the Arapaoa River on the right.
