NZ schoolboys' epic haka challenge

Video of an epic haka challenge between two arch-rivals in New Zealand's premier schoolboy rugby competition has become an online hit.

Video from before the June 14 match shows hundreds of students from Auckland Grammar spread across the field performing a fierce rendition of their school haka to the King's College first XV as their own team links arms in front of them.

Hundreds of students from the home team then respond in kind as female pupils from the school do their own performance of Poi to the side.

Auckland Grammar prevailed 27-15 in the clash, which is the biggest rivalry in Auckland's 1A competition, probably the best schoolboy rugby competition in the world.

The match between the arch-rivals attracts thousands of fans each year.
