DESCRIPTION:
The 'Kapa o Pango' is a special prematch challenge called a haka unique to the New Zealand national rugby union team. It was introduced in 2005 and was designed to reflect the multi-cultural make-up of contemporary New Zealand. Kapa o Pango was to be performed on special occasions and was not intended to replace Ka Mate, which is the standard haka.
