Former Waratahs hooker Phil Kearns was the latest commentator to earn the ire of Kiwi sports fans, unable to hide his bias as his former team went down to the Highlanders in Saturday night's Super Rugby semifinal.
Kearns railed against referee Craig Joubert, accusing the South African of having "a shocking game - there's no doubt about it". Actually, there was, and even co-commentator Rod Kafer said the referee had been fine.
In the spirit of Kearns' cheer-leading, we look at five other commentators who have at various points been caught offside with Kiwi supporters.
Mark Waugh - Cricket
New Zealand's thrilling one-wicket victory over Australia in pool play at this year's Cricket World Cup was made all the more sweet by the presence of Waugh in the commentary box. As David Warner helped Australia make a fast start at Eden Park, Waugh, a sitting Australian selector, was crowing about the players he helped to pick. But when Trent Boult ripped through the visitors' middle order, Waugh's silence was deafening.
