It was the Rugby Football League's turn to appoint the official after Australian Ashley Klein refereed last year's match, and the 31-year-old Thaler has been chosen from their eight-strong panel of full-time Super League referees.
It will be the first World Club Challenge for Thaler, who has been a Super League referee since 2005.
Warrington's Phil Bentham will be the video referee.
