That sounds more like a local airport kinda thing. I'm sure any kind of bush airport this is no problem. But not one of the busiest federal airports... thats just an entirely different scenario.
I think part of it is that even at the busiest airport on the South Island (Christchurch) this would be a doable ask for us. My boss just has no concept of what life is like in a large country, let alone a large city. He's thinking of LaGuardia Airport as just Christchurch Airport but larger.
