If you've even watched an All Blacks rugby game, you'll know of the 'haka,' a traditional Maori war dance.

The routine of aggressive chanting is often associated with power and challenge, but New Zealanders also view the haka as something to mark a bond and to welcome a guest into the family.

Benjamin and Aaliyah Armstrong were treated to one such haka at their recent wedding, when their best man, male guests (and even a bridesmaid or two) surprised them with the routine.

The moment Aaliyah bursts into tears is so special – but you'll notice she soon dusts herself off and joins in.

Aaliyah and Benjamin's video has already gone viral, and has been shared all over the world. watch it and you'll soon see why.
