Christchurch Symphony Orchestra

The Christchurch Symphony Orchestra (CSO) is the largest professional orchestra in the South Island of New Zealand, based in the city of Christchurch. It was established in 1958 as the John Ritchie String Orchestra, due to the vision and encouragement of Christchurch composer John Ritchie. It was renamed the Christchurch Civic Orchestra four years later in 1962, and has used its current name since 1974. Currently, the CSO has an established core of principal and tenured players with additional contracted casual players.
