I not only live in New Zealand, I live in Palmerston North - close to Palmerston North Boys' High School, where this performance [as shown in a video] was staged. What do I think of it? At the risk of offending my fellow New Zealanders, I have to say that I don't like it. Yes, it has the sanction of history and culture, and is performed at many (too many!) social events. But at the end of the day, it IS a war dance. It is all about bonding, being tough, intimidating your enemy, overcoming him in battle, and possibly slitting his throat. So you could say that it is, indeed, a sort of radicalization, in a nation that has rarely missed an opportunity to participate in war. If Muslims did something like this, it would be immediately held up as proof of the "warlike" nature of Islam.
