NRL referees are getting try-scoring decisions right at the highest rate since the edict to rule on tries before referring the final say to the video referee was introduced.

The referees had an 86 per cent success rate over the opening eight rounds when ruling if a try had been scored or not before sending it upstairs.

The rule was changed in 2013 to force the on-field referee to make a live decision before sending it to the video referee.

The video referee must now find suitable evidence to overturn the decision by the on-field official.
