In 2004, New Zealand were invited, being represented by the New Zealand Māori men's team and the women's representative team, the Black Ferns. In 2005, Argentina sent its A side to the men's competition. Originally, New Zealand Māori had been invited, but they declined because it would clash with their fixture with the British and Irish Lions. There was no women's competition in either 2005 or 2006, largely because of Canada's preparations to host the Women's Rugby World Cup in 2006.
