The All Blacks take on the USA Eagles in Chicago next weekend, and American fans are being encouraged to welcome the world champs by learning the haka.
All Black jersey sponsor AIG has produced a video to teach the moves of the Ka Mate haka. Viewers are taken through a step-by-step guide so they can perform the traditional challenge from the stands.
"Now we'd like you to learn the actions to the haka so you can welcome the All Blacks to Chicago with your own passionate haka," says the video, on AIG's YouTube channel:
The clip gives instructions on the correct way to quiver hands, the way to stand - "take a wide stance with knees slightly bent" - and the importance of not revealing palms. It even teaches the haka-ending facial "pukana" in which the eyes bulge and men stick out their tongues.
