Express lane, if you have checked luggage.... HAHAHAHAHAHAHAHA.
Sorry but having just done this last week, immigration has somewhat an "express lane" but after that you are one of the masses and NZ takes their bio security seriously so after you wait for your bags, you will line up in one of multiple lines to be cleared (no express for bio security) and then may or may not have your bags xrayed.
On exit from the international, you turn right and have to find the transit desk/checkin in you need a boarding pass, then domestic gate.
If I was you, I would be very very very stressed at only an hour. You would have to be very lucky to make it.
Good luck!
