Ashley Klein has again been selected by the NRL to officiate at the State of Origin level.

Regarded by head office as the best official in the game despite losing last year's grand final to Adam Gee, Klein was returned to the hot seat to do Game 1 of this year's series.

That won't change for Game 2, with the veteran official to control the match from the middle.

There have been other changes to the officiating team though, with Liam Kennedy replaced in the bunker by Grant Atkins, and Gerard Sutton replaced as the standby referee by Gee.

Gee's return to the number two status comes after last year's grand final referee missed the series opener in its entirety.

David Munro and Chris Sutton will again return to the sidelines, while Drew Oultram will travel with the refereeing squad as the standby touch judge.

Game 2 will be played at the Melbourne Cricket Ground on June 26.
