I understand it is only for NZ citizens to Australia, but for both coming to NZ. It certainly makes for a quick processing. However to USA last year it was a different matter. Oodles of bits of paper, visa,s obtained over the internet and then further checks when we got there. My husband is a coeliac and has very/nil fingerprints, and it looked as if they were not going to let him in. Fortunately we were able to convince them he was who he said he was and they let him in.
