As with tai chi and other Asian martial arts, every action, movement and weapon-hold in mau rakau is designed to strengthen and make the body more flexible, as much as to defend or attack.
The resurgence of interest in Maori weaponry skills has seen it recognised internationally as a martial art, just as kapa haka is recognised on the world entertainment stage, Mr Rapana said.
Mau rakau is one of the traditional arts performed in daily sessions at Waitangi Treaty Grounds.
A former kapa haka teacher and national champion, Mr Rapana took over the cultural performance reins at the Waitangi Treaty Grounds last October, before which he had been working as a tutor at the University of Auckland. He designed the show that has become a popular part of the Waitangi visitors' experience.
He was a senior member of the 2009 national kapa haka champions Te Waka Huia.
