At Beyonce's October 19 concert in New Zealand the crew at Auckland's Vector Arena greeted Sacha Fierce with the Haka, the traditional Maori war dance used to intimidate opponents before battle.

Currently, the Haka is performed by the New Zealand All Blacks rugby team before each match and is a well-known tradition in NZ.

The local crew comprised of stagehands and techies chanted, hollered, stuck out their tongues, slapped themselves and a whole lot more -- and Mrs. Carter followed suit. We knew she was game for stuff like this!

Bathed in blue flashing light, the 32-year-old icon approached the 25 shouting men and fired back. The "Irreplaceable" songstress stood and delivered her own fierce warrior face and emulated their moves back to the pumped-up crowd.

We love that Beyonce joined in and we love that she seems so ticked by the dance, which is also used to honor distinguished guests.
