Dunedin–Waitati Highway (SH 1), formerly (and currently in official land-use planning contexts) called Dunedin Northern Motorway, is a two-to-four-lane limited-access road which provides the main route north from the city of Dunedin, New Zealand. Opened on 14 December 1957, it superseded the narrow and winding routes via Port Chalmers and Mount Cargill. The road is occasionally briefly closed by snowfall in winter.
