Gosh Nynae chip on your shoulder much? I said New Zealand, not Europeans.
I think you are being argumentative for the sake of it. Acyually there was very little evidence of Maori culture in much of New Zealand 30 years ago. But since then Maori has been become the official language of NZ along with English and, more recently, sign language.
Te Reo has become part of the school curriculum and the pre school curriculum has only one title, Te Whaariki. Kapahaka and Pasifika groups are commonplace in schools.
We now have Maori TV and Maori performances at every big event.
This is a massive revival of Maori culture, and it wasn't brought about by your suggested Europeans, but by the very many New Zealanders who felt the Maori culture had been marginalised and the language was perilously close to dying out. It really wasn't so long ago that teachers were paid dirt money to teach Maori children. But you knew that, right?
To posters suggesting the haka should not be performed by non Maori (Samoans etc), you do realise that not all Maori have brown skin?
