In the Auckland Museum, and elsewhere, you can enjoy a show of "authentic" Maori dances and songs. This is pure folklore: the dances and songs were accompanied by an (amplified) accoustic guitar player which I'm prepared to bet anything the Maoris didn't have.
Then there's their wood-carving. Very intricate and technically accomplished. But it completely lacks the simplicity and minimalism I happen to like (the work of Saul Bass, and what I love in Japan; or what we found in Vancouver.) So I couldn't get into it.
And all those tattoos! Let it go, already.
