 It has been affectionately dubbed 'The Woolshed' by Canterbury Rams basketball fans. Some Christchurch citizens colloquially refer to the arena as the horseshoe, due to its unusual architectural exterior design.
 Construction company Chas S Luney Ltd built the stadium. The arena opened in September 1998 at a cost of NZ$32 Million. In the first ever sporting match at CBS Canterbury Arena, the Canterbury Rams basketball team suffered a close loss to the Wellington Saints 86–81 in April 1999.
 It was built for two main reasons: primarily for the 1999 Netball World Cup in Christchurch, and also because Christchurch was missing out on many concerts and other attractions, because it did not have a suitable indoor arena in the city.
