The NRL has responded to criticism of its bunker by reducing the scope of the decision review system's power.
The bunker will no longer be used to determine knock-ons in general play or be called upon for 40-20 calls in 2017.
It will only rule on point-scoring plays, in-goal restarts and reportable foul play.
NRL officiating boss Tony Archer said the bunker was hampered by confusion of jurisdiction in its inaugural season last year.
"From goal line to goal line, we expect the on-field officials to make the call. This makes it much clearer," Archer told reporters on Tuesday.
