15 teams

Draw made for Super Rugby 2018

With three teams having left the 18-team four-conference competition is now a 15-team, three-conference format.

Gone are South African sides the Southern Kings and Cheetahs, who have joined the European Pro14 competition, and Australian team the Western Force.

Next year each team will play 16 conference matches, with eight matches within their own conference home and away, then four matches against teams from each of the other two conferences.
