[4] The WNBL decided in October 2006 to add the Sirens along with the Bendigo Spirit to the league for the 2007–08 season.

[6] Their name was inspired by the mythological sirens and their red and black colours were regionally associated with Christchurch and Canterbury.

[2] After one season, the Sirens were unable to secure sponsors to raise the estimated NZD$600,000 required to stay in the league.

[7] Basketball New Zealand decided against bailing the team out as they were short on reserves and couldn't justify the risk.

[8] In spite of the team's collapse, Basketball New Zealand still had to pay NZD$250,000 to Basketball Australia in accordance with terms of its five-year licence agreement, including an annual AUD$50,000 entry fee for 4 years.
