Sanzar chief executive Greg Peters said the changes would operate throughout the Super 15 and results would be monitored by the International Rugby Board.
The aim was to help referees and deliver greater consistency across judicial hearings in New Zealand, Australia and South Africa. Officials were briefed on the changes at a cross-country working group forum recently in Sydney.
Until now, teams had four hours after a game to refer any opponents they felt had been guilty of foul play while the citing commissioner had 12 hours to cite any individuals.
The revised system encourages referees to be more vigilant about offenders instead of leaving most of the onus on citing commissioners, while Sanzar has been working hard to get uniform penalties instead of "hometown decisions" in judicial hearings.
Setting uniform penalties is an obvious step on the path of removing those suggestions of "hometown bias".
Peters said the objectives of the review were to provide a system that was fair, and consistent and simple with fewer full hearings and therefore reduced costs.
"Sanzar has long held the view that the disciplinary process could be enhanced to provide for a more consistent and simplified outcome," he added.
"We believe that these changes are an important step in the right direction."
