It works exactly the same way. On my last AKL stay, they were doing cruise check ins at AKL, so you had nothing to do except go thru security and walk onto the ship when we got to port. Luggage pick up a few minutes after 8 am (we were told to have it ready by 8). Told to be in lobby an hour before pick up was scheduled. I talked to CM the day before and she said she could do the check in any time on the morning of the departure, and could even check documents the day before (but not issue KTTW, etc. till the morning).
We hit one resort after AKL, then on to the port. Quite painless. I don't like arriving at port at 1:30, but it makes sense sometimes.....
