The All Blacks' pre-match "throat-slitting" gesture may be making a return for the Rugby World Cup.
The final act of the alternative haka Kapa o Pango, an aggressive drawing of the thumb across the neck, was toned down after complaints from the public and opposing sides.
A Rugby Union review of the newer haka in 2006 concluded it was not offensive, but nevertheless it was changed in 2007 to a raking gesture across the chest.
But before Saturday's Bledisloe Cup match several players, including haka leader Piri Weepu, appeared to have reverted to the original gesture.
It did not go unnoticed, and many Australian newspapers referred to its chilling effect.
