Super Rugby will scrap the four-try bonus point for the 2016 season, instead introducing a system similar to that already used in France's Top 14.
Teams will now be awarded an additional point should they finish a match with a minimum of three tries more than their opponent, SANZAAR confirmed on Tuesday.
Among other rule changes to be brought in ahead of the new campaign is the option for teams to opt for a lineout if they are awarded a penalty after time has expired, and a 60-second limit for kickers to take their shot from the time a try has been scored or a penalty has been awarded.
"These law amendments, while subtle in nature, will help Super Rugby's continuing evolution as the best provincial competition in the world," SANZAAR CEO Andy Marinos said.
"The change to the bonus point, which has been widely discussed throughout the past week as one potential innovation, has now been formally approved by the ExCo for the 2016 season.
"By implementing this change, we expect to see more attacking and competitive rugby as teams will be asked to keep their foot down for the full 80 in order to claim the try-scoring bonus point, which we have seen used to great effect in France over the past few years.
"In addition to this, permitting teams to opt for a lineout after time has expired serves to disincentive opponents from infringing and aims to reward sides that are particularly strong set-piece exponents."
Changes to the use of the television match official (TMO) have been placed on hold until a World Rugby TMO review is complete.
