The Roxburgh Dam is the earliest of the large hydroelectric projects in the southern South Island of New Zealand. It lies across the Clutha River / Mata-Au, some 160 kilometres (99 mi) from Dunedin, some 9 kilometres (5.6 mi) to the north of the town of Roxburgh. The settlement of Lake Roxburgh Village close to the western edge of the dam.
The dam was constructed by a joint venture company between Holland, Hannen & Cubitts of the UK and S A Conrad Zschokke of Switzerland between 1949 and 1953. Because of a lack of performance the initial contract was closed in 1953 and a new contract in which the original two companies were joined by Downer, a New Zealand construction company completed the main construction of the Station in 1957. The power station was commissioned over the period 1956-1962.
