For a "living" culture to be worthy of that designation, it should demonstrate an ability to adapt and grow in an almost organic way with the community it serves.
The alternative is for a culture to remain emblematic of a period in the past. Cultures in these circumstances tend eventually to acquire the traits of dusty museum exhibits: revered for their antiquity but largely irrelevant.
What happens, though, when there is a shrill call for a cultural practice to be changed abruptly? This is the question facing Parliament's Speaker, David Carter, who has sought a review of Maori protocols at Parliament following concerns expressed by Labour MPs Annette King and Maryan Street at being asked to move from the front row of a powhiri at the start of the Youth Parliament a few months ago.
Carter's response is instructive for the attitude it reveals towards aspects of Maori culture. He wants to "modernise" certain protocols so that they are "acceptable to a diversified Parliament". On the surface, this seems like a fair undertaking, yet several aspects deserve closer consideration.
The first is the appropriateness of two seasoned MPs questioning a protocol whose tenets are long-established and well known to the complainants. If seating arrangements at powhiri were so pressing to these MPs, presumably they would not have waited so many years before requesting action. A cynic might suggest there are other motives at play, but what these could be is anyone's guess.
