Haka isn't just a war dance. It is a form of expression for a people who has no writing. So there are therefore different kind of haka : warrior, mythical, ceremonial, funerary.
To celebrate a wedding, haka is traditional.
If members know the history of haka, I think many of us are applicants.

While looking for websites on the haka, I found this one in the archieves of the French TV :

Without being complete, it clears a little our preconceptions. Icing on the cake, it is here transleted into English (for the few members who don't speak French  )
