The NRL is set to trial an NHL-style video referee bunker midway through the season to determine whether it produces better and faster decisions.

NRL head of football Todd Greenberg said the video referees would operate from a central command centre with access to every available camera angle, but the current video refereeing system would remain in use for the selected games and to provide a genuine comparison.

Greenberg said it was hoped that the bunker system would provide greater accuracy and consistency by video referees in quicker time.

"A video referee sits in a box with one screen and he only sees what the producer from the broadcast gives him," Greenberg said. "Sitting in a central command area you would have a screen for every camera at every opportunity in the game in real time.
