but didn't the All Blacks change the gesture to be across the chest as a result of the initial disquiet over Kapo o Pango?
Nope, maybe one or two of them changed, most still go across throat. Funny how it's only been brought up now.
Here's a 2016 version, watch Izzy Dagg (second row from front, on right) at about 1.15 https://youtu.be/Z60PGuxnHmw
a) There was a huge outcry at the time
b) they definitely changed it
"Kapa o Pango" concludes with what has been interpreted as a "throat slitting" gesture that led to accusations that "Kapa o Pango" encourages violence, and sends the wrong message to All Blacks fans. However, according to Lardelli, the gesture represents "drawing vital energy into the heart and lungs".
The All Blacks opted not to perform "Kapa o Pango" in their opening test of 2006 against Ireland. It was requested that they perform their usual "Ka Mate" haka while a review was conducted into "Kapa o Pango". The throat-slitting action at the end of "Kapa o Pango" had drawn many complaints in the lead-up to the Irish test, with members of the public complaining about it to the NZRU.
The NZRU said that it was not because of public pressure that it was not performed against Ireland.
In the run-up to the first All Blacks Test of the 2006 Tri Nations at Jade Stadium in Christchurch against Australia, the NZRU completed their review, and concluded that the gesture had a radically different meaning within Māori culture and haka traditions, indicating the drawing of "hauora", the breath of life into the heart and lungs. As a result, "Kapa o Pango" was performed, complete with the final gesture, before the Australia test.
Despite this, the controversial gesture was withdrawn in 2007, with a modified action (raking the right arm from the left hip to over the right shoulder) performed in the challenge when "Kapa o Pango" was performed in test matches against France and South Africa
. During the 2008 Tri Nations series, the All Blacks appear to have reverted to the original action of drawing the hand across the throat.
