Waitati, from the Māori Waitete,^[4][5] is a small seaside settlement in Otago, New Zealand, within the city limits of Dunedin. It is located close to the tidal mudflats of Blueskin Bay, 19 kilometres north of the Dunedin city centre. The small Waitati River flows through the bay to the sea.

The Dunedin–Waitati Highway section of State Highway 1, formerly and colloquially called Dunedin Northern Motorway, ends at Waitati; the highway continues north from here at a slightly lower grade of construction with more frequent intersections and accesses.

The old station yard remains as a train crossing loop and parts of the old station building are used by rail maintenance workers.
