I don't know. It seems more to me that New Zealand is desperately trying to cling to the movies' success far, far, FAR more than Warner Brothers is trying to take over a country's government. The latter is just kind of silly since they've been making big movies for decades, whereas New Zealand is a tiny little country that's suddenly getting huge injections of money from its production and tourism due to the movies.
I mean, if the government comes to you asking what they can do to help you make a huge profit and all but throwing themselves at the chance to jump through any hoops you want to hold up, why wouldn't
you take advantage of that?
