Watch: Wellington high school students perform powerful haka

Wellington schools have shown their support for those murdered in the Christchurch massacre, with a powerful haka.

Students from Otaki College, Paraparaumu College and Kapiti College stood in formation to resemble Te Raukura - a plume of white feathers that represents spiritual, physical and communal harmony and unity.

The three schools all observed a minute's silence at 1.39pm, and then, at the exact moment the attacker opened fire last week, they delivered a rousing haka.

It was organised by Kapiti Mayor K Gurunathan, and Porirua Mayor Mike Tana.

"As a migrant who has found a home here, I know there can be no other response as powerful and deep seated in the New Zealand psyche than the haka, which has the ability to unite all Kiwis," said Gurunathan.

"We stand with all our communities to support Christchurch. Unity will show strength and the way forward," said Tana.
