Earlier quoted context omitted.
New Zealand is a sovereign nation. One that has laws which established residency for Kim Dotcom. And one that has signed international treaties with other sovereign nations. New Zealand has used their own judicial system to reach this decision. They are behaving in accordance to their own laws and agreements they were willing participants to. In short, there's nothing wrong here. Not in the slightest.
As a kiwi. This entire case makes me sick. This should have been thrown out of court a long time ago. This is a political move and nothing else. It's NZ on its knees sucking off the United States. From day 1 it's been illegal. Hidden process, and laws changed to make the process more legal. I hate my country now.
Here's another possible angle: Hollywood might actually be contributing favorably to New Zealand's economy, either directly or indirectly (e.g. through increasing tourism), when it films movies like Avatar, LOTR and The Hobbit. See, for instance http://www.forbes.com/sites/carolpinchefsky/2012/12/14/the-i.... In 2014, the screen industry revenue was NZ$3 billion (see http://www.stats.govt.nz/browse_for_stats/industry_sectors/f...).
This guy was directly undermining Hollywood's business, which meant it could also undermine New Zealand's movie industry, implying it was also in New Zealand's interests to bring him to justice.
