The town of Palmerston, in New Zealand's South Island, lies 50 kilometres to the north of the city of Dunedin. It is the largest town in the Waihemo Ward of the Waitaki District, with a population of 890 residents. Palmerston grew at a major road junction: State Highway 1 links Dunedin and Waikouaiti to the south with Oamaru and Christchurch to the north, while State Highway 85 (known colloquially as "The Pigroot") heads inland to become the principal highway of the Maniototo. The Main South Line railway passes through the town and the Seasider tourist train travels from Dunedin to Palmerston and back once or twice a week.
