"For the last 12 months the ANZ Championship has been conducting a review, including reviewing 10,000 survey responses from fans, into the future timing and structure of the league to ensure it remains a world-class and vibrant competition," Crook said.
"We're confident that the introduction of conferences will ensure that every match played throughout the regular season will have significance towards finals standings and intra-country rivalries,"Crook said.
Stage one of the revamped finals format would see teams that finishing first in the Australian and New Zealand conferences have the bye in the opening week of finals with the second and third-placed sides contesting an intra-conference elimination on either side of the Tasman. The winners of the matches will progress to the second week for a conference final to decide the Australian and New Zealand champions, but no team will be eliminated at this point.
The second stage will see transtasman semifinals and the ANZ Championship grand final in weeks three and four, ensuring the best performing teams play-off for the ultimate prize of lifting the ANZ Championship trophy and increasing the number of finals matches from four to seven in the process.
"The review has provided us with an opportunity to revisit the structure of the ANZ Championship's finals series, which is our opportunity to showcase our competition, so a restructure will improve our finals product through more intraconference rivalries and critical games," Crook said.
While the new competition structure has not been finalised yet, transtasman league officials have confirmed they will introduce a separate challenge, which will operate in a similar way to provincial rugby's Ranfurly Shield. The as yet unnamed 'challenge system' will run concurrently with the existing season and not include play-off matches.
"The challenge competition ... supports our ambition of establishing long and proud traditions in the ANZ Championship for many years to come," Crook said.
