Chiefs boss Dave Rennie revealed that he found out about the bonus point changes in Super Rugby through an email rather than being consulted.
Rennie revealed that a planned conference for coaches and officials in November last year to discuss the change amongst other issues had been cancelled.
An announcement is expected shortly from SANZAR confirming that the four-try bonus point has been scrapped in favour of the model used in the Top 14, where a team is awarded an attacking bonus point if they outscore their opponent by three tries.
"To find out through an email, this is how it's going to be, is obviously frustrating," Rennie told Radio Sport.
"At no stage was this talked about, so it's frustrating we've had no say in this.
"There was supposed to be a conference in November with all the coaches going to it, and then they cancelled it. It was a chance for coaches and referees to sit in one room and discuss a lot of things, so we've really missed an opportunity there."
Rennie revealed that the idea had been rejected in the past. He also doesn't believe that the new regulation will necessarily change the way that teams play the game.
"It was brought up a couple of years ago as an idea adopted from France and we squashed it pretty quickly," he added.
"For us, of all the things that we could change in our game that would make it better and easier to watch, the bonus point system wasn't one of them.
"The trouble with this is SANZAR are trying to make changes that will force us to play a certain way but, realistically, teams will play the way they want to play.
"They think that if you score four tries and the opposition has scored two you've got to keep playing and it's got to make the game better. But realistically, if a team, let's say we're up by four tries with 20 to go, we may say, 'oh, we're going to close shop' because the only way the opposition are going to score is by us making mistakes. So you end up slowing the game down and playing less."
