A common complaint has been the complexity and unfairness of the four-conference system which sees some teams miss New Zealand sides - invariably among the strongest - for the entirety of the round-robin. The truth too is that the depth of the player base in Australia and South Africa cannot justify the number of teams they have at the moment - their talent is spread too thinly.
Pointedly, Andy Marinos, Sanzaar's chief executive, mentioned the feedback of supporters as a major driver of change, adding: "This has been a long and complex piece of work and we make no apology for that. Super Rugby is unique in world rugby in that it is played in six countries across 15 time zones and has numerous stakeholders."
"Sanzaar cannot continue to ignore the extensive feedback that it has received from fans, stakeholders and commercial partners around the integrity of the competition format and performances of the teams. We want to see an engaging, vibrant and competitive competition that delivers a strong high performance pathway in all markets that will have a positive flow into the international game."
Sanzaar chairman, Brent Impey, who is also New Zealand Rugby's chairman, said: "This decision has not been an easy one and we recognise the difficulty associated with reducing the number of teams in Australia and South Africa. Naturally we understand that there will be some very disappointed franchises but the tournament's long-term future and the economic reality of the business at present is something that had to be addressed."
"The decision to retain the Sunwolves is linked directly to Sanzaar's strategic plan for the future. The potential for growth of the sport in Asia off the back of the establishment of the Sunwolves and the impending RWC in 2019 is significant. It remains an obvious focus for the organisation and a Japanese Super Rugby franchise is key to that strategy."
New Zealand Rugby Chief Executive Steve Tew welcomed the changes.
"Sanzaar unions have worked hard on very difficult issues to ensure the best outcome, securing a strong future for the competition and all the Sanzaar nations. I commend all those involved in discussions as the impact has been different for everyone," said Tew.
"From a New Zealand perspective, the strength of all teams is essential to ensure that New Zealand clubs can be successful on and off the field, while providing a fantastic platform for the best players in the world to be on display."
