South Africa's newly formed Southern Kings have lodged interest in becoming the 15th team to join Super rugby in 2011.
The combined Eastern Province, Border and South Western Districts franchise, is the only organisation to respond to South Africa Rugby's call for expressions of interest.
Hawkes Bay, Taranaki and seven Australian groups have lodged their interest to form a side in the revamped competition, which will see 15 teams split into three conferences.
SANZAR has agreed the new team will play in the Australian conference with a final decision expected in late October.
Australia has four teams in the Super 14 compared with New Zealand and South Africa's five, and is considered to have the inside running, despite concerns over its player depth as none of its teams made the semi-finals this season.
