Good info from Mowie, I couldn't recall the ASL web site. A foreign ATPL equivelant likely is the FAA, but I will try and get a hold of a mate on the hiring board and ask. I did have one in hand, and I think the military guys at least had a commercial. All you would require for a right seat at Pac Blue is the written, medical and log book certified. Remember, you'll require that letter from the CAA stateing that your hours meet the requirment for ATPL conversion.
I think it was Air Whanganui who had the Pnavajo that you could do the ATPL flight test in. If it was me, 'cause this is exactly what I did, I'd just get the paperwork out of the way and do the ATPL ride with the friendly person who hires you; they have to do a check ride anyway.
PM me with a time in AKL and I'll let you know if I'll be around. I'm in Shanghai from the 30 April until the morning of the 5th May, then just a quick SFO and back, so I should be around.
Good luck
