Australian referee Rohan Hoffmann and New Zealand television match official Vinny Munro have been singled out for their poor officiating in round 14 of the Super Rugby over the weekend in SANZAR's weekly review into performances.

A SANZAR statement released late on Monday afternoon on match official appointments for round 15 did not name and shame the pair but Fairfax Media understands that Hoffmann and Munro were at the centre of the governing body's ire.

In Hoffmann's refereeing of the Waratahs-Sharks game at Allianz Stadium on Saturday that the Sharks lost 33-18, his calls against the visitors arguably eliminated their hopes of winning the game.

Hoffmann will be one of two assistant referees with Graham Cooper in Saturday's Force-Highlanders clash in Perth that Andrew Lees will referee.
