SANZAR CEO Greg Peters has revealed that his organization is open to holding talks over the expansion of Super Rugby.

The current conference-based format is locked in until 2015 due to the broadcasting deal Peters has revealed that the Southern Hemisphere's governing body would be open to altering the shape of the tournament in the future.

"We will certainly start to consider it. It is another thing that the conference format allows us to do and, we can add teams and add conferences," Peters told ESPNScrum.

"When we look at 2016 onwards, we have no closed views on what the future may look like and our current format allows us to expand should we wish to and should it be in the best interests of the three SANZAR countries to do so because that is why we do this."

The current conference system has come in for criticism, especially in 2012 as Australia got an advantage despite their top team finishing behind some of South Africa and New Zealand's second and third placed teams on log points.

Last season's Super Rugby champions the Reds won the Australian conference again this year which earned them a home play off despite having the least number of log points of all the top six teams.

Each country has five teams in three conferences to make a total of fifteen teams but South Africa want a sixth team so they are keen to have the tournament expanded to accommodate the Southern Kings.

However to keep the conferences balanced at five teams each SANZAR may have to look further afield than the existing countries which could open the door for Argentina, Japan, the USA and the Pacific Islands.

Peters said that SANZAR is committed to doing what is best for the existing countries so if they want to keep the standard of rugby the same 2016 may come too soon for some of the new territories being considered.

Argentina will join the Rugby Championship but giving them a Super Rugby team as well would probably see them playing the same team in both tournaments as they have to build up depth.

The big problem for SANZAR with expansion now though would be travel as the teams already have to suffer too many long flights for professional sportsmen and adding flights to Japan or Argentina will only make the problem worse.
