I was in AKL a couple weeks ago (flying CX PE) and found out that CX uses the NZ/*A lounge instead of the QF lounge. Not sure why they do that, but it's not exactly seamless. The BP scanners at the NZ lounge can't read a mobile BP, so it took several minutes for them to admit me. I have a feeling the QF lounge would've been a much smoother experience.

That said, the Air NZ lounge is very nice.
