Halfway Bush is a suburb of the New Zealand city of Dunedin. It is located 3 kilometres (1.9 mi) to the northwest of the city centre, close to the point at which Taieri Road becomes the winding rural Three Mile Hill Road. It was this road which gave the suburb its name, as this locality was halfway between the Taieri Plains and central Dunedin in the early days of European settlement, when Three Mile Hill was the main route from Dunedin to the Otago hinterland. This route was superseded by the route through the Caversham Valley in the 1860s.
