The one little hop in NZ will be tolerable. I did kick in the $20 for
an exit row seat.
Personally I find the layover worse than the flight. We are stuck at
LAX for 9 hours or so. Some of it will be clearing customs but I
still would like to check my stuff and hop in a cab. I may call an LA
friend and meet them for dinner or something.
I am looking at opening a New Zealand bank account right now.
Make sure you have a chip credit card. And get a no foreign transaction
fee card. Chase Sapphire is free for the first year at least and has no
extra foreign fees added. Lots add 3.5%. Our chip cards are chip and
signature and not chip and pin like the rest of the world.
