Adam Smith noted cities were founded on "navigable rivers", because that's how trade works. Still true today for cargo ships. But today the internet is a river everywhere, for information goods.
New Zealand is the most beautiful place in the world, in my travels (circumvented the globe, but not been everywhere). Though I'm biased towards mountains.
So, theoretically, beauty+internet makes it a great place for software developers (and other information goods and services producers).
OTOH, NZ has prevented software patents (one of the few countries in the world to do so). Although many software developers love this, consider the question: will it increase investment in patentable inventions, or decrease it?
But in a way it's irrelevant: NZ itself is a tiny market. What counts is patents in other markets, US, Europe, Asia.
