Oamaru is the largest town in North Otago, in the South Island of New Zealand, and is the main town in the Waitaki District. It is 80 kilometres south of Timaru and 120 kilometres north of Dunedin, on the Pacific coast, and is connected to both by State Highway 1 and the Main South Line. Its historic status as the second centre in the Otago Region (after Dunedin) is under threat from the growth of Queenstown in Central Otago. Regular air services from Oamaru Airport are provided by Air New Zealand subsidiary Eagle Airways to Christchurch.
