That reminds me , alot of new zealanders say KIA ORA, its a maori word meaning hello, our indigenous people here, some european people get offended, but i say hey we have to embrace both our cultures, and i think it sounds nice and unique to N.Z.
My daughter has just spent a night at a maori marae part of her schooling, so she is learning the maori customs and way of life, i cant see any harm in it.
