Thanks algrove! I can really recommend visiting New Zealand.
Whether this justifies a long distance flight, both from personal and ecological point of view, is a very difficult question.
On the one hand, I think traveling always opens the mind and gives new perspectives and therefore helps to improve humanity.
On the other hand, I'm thinking nowadays more and more about my carbon footprint and ask myself whether a flight around the world for a 3-4 weeks photography trip or vacation makes sense.
