 In November 2006 , at the Millennium Stadium , Cardiff , New Zealand performed the haka in the dressing room prior to the match – instead of on the field immediately before kick @-@ off – after a disagreement with the Welsh Rugby Union , which had wanted Wales to sing their national anthem after the haka . In 2008 , New Zealand played Munster at Thomond Park . Before the match , Munster 's four New Zealanders challenged their opponents by performing a haka before the All Blacks started theirs . On the same tour , Wales responded by silently refusing to move after New Zealand 's haka , and the two teams simply stared at each other until the referee forced them to start the game .
