You say your routing is ultimately to AKL.
Please take a long look at this thread as you are almost certainly affected and this will likely be why you're having problems with finding relevant seat maps for your flights:

Unless you've already done so you will need to contact Qatar Airways to discuss alternative routing possibilities and have your ticket reissued accordingly. I was flying 10 days prior to you on the same route (PSA-DOH-AKL) and have had to change my travel plans. Do so sooner than later as flights are likely to be extremely busy.

Do let us know how you get on and good luck!
