Along with New Zealand's other Super Rugby sides, the Blues were established by the NZRU to take part in the newly formed Super 12 competition which, involved teams from South Africa and Australia in addition to New Zealand. Each of New Zealand's five sides represented a number of provincial unions, with the Blues representing the Auckland, Counties Manukau and Thames Valley unions, while the neighbouring Waikato Chiefs representing the Waikato, Bay of Plenty, King Country, Northland and North Harbour unions. As the amount of international representatives in the Auckland region was thought to be unfair, it was split up between The Blues and The Chiefs. During this era, the Blues played the majority of their home matches at Eden Park, with round robin fixtures occasionally held at Growers Stadium in Pukekohe.
