New Zealand now has its own Tea Party, pushing the same brand of less tax, less government, climate-change denial and racism seen in the US. The problem for them is that this niche is already well-populated, most notably by ACT, but also by other minnow parties such as Libertarianz and the Sovereignty Party. Meaning that even if they do manage to scrape up the 500 members required for registration, they're unlikely to get anywhere.
