SANZAR, creators of both the Tri Nations and Super Rugby tournaments, dismissed the idea which proposed a series of 40-minute matches played between franchises.
The concept was penned by former Springbok Rassie Erasmus and would also involve a revised set of rules reducing the amount of kicking during matches.
“SANZAR’s representatives met with the promoters of the competition so as to better understand what was envisaged and because we are always open to any ideas that might help promote rugby in our three countries,” SANZAR chief executive Steve Tew said.
“However, having considered the concept and the way in which it has been developed; SANZAR has decided it has no interest in any further discussion of the proposed competition.”
The plan was scheduled for the rest period in southern hemisphere rugby and would also eat into the preparation time for the Super 15 franchises ahead of their domestic season.
The Aviva Premiership is currently running a premiership Sevens series which is deemed by many to be a short enough form of the game.
