. . "The Waitaki district, in the Canterbury and Otago regions of New Zealand, straddles the traditional border between the two regions, the Waitaki River. It has a land area of 7,151.94 km\u00B2 (2,761.38 sq mi), divided 59.28% to Canterbury Region and 40.72% to Otago Region. It is the only district in the South Island that is divided between two regions. A major reason for this split was the governance of the Waitaki River which forms a political boundary between Canterbury and Otago."@en .
