Those Kiwis are nothing if not adaptable. Not only are they a world rugby power, but they play some US-style gridiron football as well.
The national team is the New Zealand Haka, and their web site is located at http://haka.freeservers.com. Take a look. They toured the US once and played some colleges in Utah. (There's that Mormon/New Zealand connection again. I'll have to investigate…)
I get a kick out of the photo showing guys in pads and helmets doing a pre-game haka before a 1997 game against the Bushrangers from Australia.
The parent organization of the Haka is Gridiron New Zealand.
How did rugby become gridiron in the United States? That story may be read by clicking here.
