I was in NZ
back in the summer of 2003. As I was with a group of people, I didn't get to do a lot of spotting, but I did still manage to get some pics. An airport that I found that has a very scenic backdrop is Queenstown which is on the South Island. It's about a 6 hr. drive from Christchurch, or a fairly short flight. As far as weather goes, at the beginning of may, ZQN
is in the Fall. When I was there in June Winter just began. Traffic at ZQN
comprises of ATR's and 737's mainly, so there's not a lot of big stuff, but the views pretty much make up for that. The airport is served by 3 airlines - Air New Zealand, Qantas, and Origin Pacific. The approach into ZQN
is also stunning - you are surrounded on both sides by mountains which makes for some great views. The airport is roughly 5 mi from the city, which has a nice selection of bars and things to do.
has a nice variety of aircraft, but I didn't get to check out any spotting locations. I am not sure about the current situation with law enforcement at these airports but since they are in NZ
I imagine that the situations can't be too bad. If you do go in May, the temperatures can get pretty chilly down there. If you have any questions feel free to ask.
