From the Law Library of Congress, a new report: New Zealand: Maori Culture and Intellectual Property Law.
The protection of the traditional cultural expressions of indigenous people from inappropriate use raises issues relating to the differences between standard intellectual property concepts and the “worldview” of such groups.
This report might ring some bells in Canada. The Maoris work to maintain traditional forms while addressing current issues, as in this powerful video. As usual, one of the main troubles is actually cashing the cheque. Perhaps a tipping point is approaching, especially for those with some cultural capital.
