The NRL is planning a radical move that could see up to 10 officials controlling games as early as round one of the 2015 season.

The move will be tested for the first time at the annual Charity Shield clash between South Sydney and St George Illawarra on Saturday, where two referees will be joined by four sideline officials, two video referees and the return of two in-goal touch judges.

If successful, the extra officials could be in use from round one, according to referees' boss Tony Archer.

"At this stage we're only looking at it as an experiment," Archer said. "We have to see what is the best system. For us, it's about looking to be the most accurate decision-makers we can be and to get as many decisions right.
