I did not actually see this, myself. Here is my interpretation of what someone told me.
While he was watching the Australian All-Blacks get ready for the game, they went thru some exercise doing a chant. The way he described the exercise, it sounded sorta like the Maori warriors psych-out routine, where they stamp around and such.
Anyway, the announcer said (according to him), “Now [some player] is leading the and “some player” is leading the ???”
So what was he leading? My co-worker thought it started with an “h” and apparently be roughly synonymous with “chant” or “war cry.” It could be some English, Australian, Aboriginal, or even Maori word.
Any ideas???
They were probably doing the “huka”.
The allblacks are not Australian but are New Zealanders (Kiwis)
The huka is a traditional maori song/dance, take a look at this site for more details

That’s haka, messiah, but that’s a good link.
And Mjollnir, the Kiwis would probably stone you for suggesting the All-Blacks were Australian, of all things. 
That’s like telling a Bostonite you thought the Red Sox were from New York.
Hakas are a traditional Maori form of greeting or sometimes challenge; I once saw a group of Maori reggae fans greet Toots and the Maytals at the Wellington airport by performing one.
It’s a very peculiar custom. Try to imagine a U.S. NFL team (the players) doing an Apache war dance before every game.
Yeah, that’s a big faux pas. My co-worker thought they were Aussies, and I took him at his word.
