As for your edit about NZ's economy being mainly "services", if you subtract industries owned/controlled by Australia/US/UK (e.g banks, TV content), re-apportion industries servicing the Ag/Meat/Milk/Wool/Forestry/Fisheries industry as being part of that industry, and do similar for industries servicing "Human Arrivals" (e.g. house construction being part of Immigration/International Ed), then you end up with the two big drivers of New Zealand's economy: Human Arrivals and Primary Production. They don't fit into the official categories in the govt's accounting system, but they're the real engines of NZ's economy. The rest are just hangers-on.
