I'd argue that it's naive to think that increased charges will benefit all New Zealanders. New Zealand hunters certainly wouldn't see any benefit from it. I don't think anyone at grassroots level in the tourism / hunting industry would benefit. I also don't think it'd deter many people at the end of the day.
Net effect? Less NZ'ers gainfully employed, more at the top lining their pockets, local hunters still "disenfranchised".
