I always find this topic fun. I’ve flown into Queenstown, Dunedin, Nelson, Christchurch, Wellington, Auckland, Gisborne, Hamilton, and Whangarei. I can totally understand the difficulty of Queenstown as it’s a busy airport surrounded by mountains.
My most clench-worthy flights have come from landing in Whangarei in bad weather, though: it’s exposed on a hill and has a short runway, and having lived around the airport I know exactly how much runway is left while the plane is still going quite fast. (It’s not much.)
Surprisingly, apart from being fogged in during a layover, I haven’t had any bad landings at Wellington.
I recall Taupō has been mentioned, not in this article but elsewhere, not because of the technical skill but because it is the busiest uncontrolled airport (it has no air traffic control).
It seems odd to list Wellington on international lists when it doesn’t even get much of a mention on a national list.
