For more than a century Kiwi rugby players have been performing haka before matches and now two referees have joined in - recreating referee signals using traditional haka actions.
Richard Tuhaka and Troy Para Snr, from Ngati Porou East Coast Rugby Football Union (ECRFU), show off their moves in a video created by the Ruatoria based union to celebrate its "unique identity as the only iwi based rugby union in the world".
In the clip the two men perform traditional haka actions similar to common rugby refereeing signals while standing in front of a blue ECRFU ute.
The names of the referee signals in te reo Maori and English appear on screen in text when the men demonstrate them.
The union released the video on its website as part of the launch of te reo whutupöro - an initiative celebrating te reo Maori.
