Lindsay Perigo, a prominent libertarian in NZ, has shown that an active libertarian can make a difference. He has his own radio show and his magazine, Free Radical , goes out to 1,500 people. That may not seem like a lot but adjusted for population size that makes its circulation larger than Reason or Liberty in the United States. Libertarians could survive there on the practical level as well. The economy is well developed and first world in nature.
Unemployment is low and opportunities abound.
It has all the first world amenities that most of us want. We would have the choice of restaurants, theater, etc that we want. It has higher educational opportunities and decent medical care. Auckland is a major city with well over one million residents. This means that urban libertarians could feel right at home there but those of us who prefer seclusion have the entire rest of the country from which to pick.
