I had heard that the aircraft was a regular pax 767 with a belly full of cargo, and combined with seeing the flight listed on the pax boards at AKL I thought there might be the off chance that a (very) limited pax load would be taken. Thanks everyone else for constructive responses.
I think that may have been the case in the past. I also heard that they have 767 crews on assigned leave and with some 767 airframes hanging around whilst they got the US guys in to fly with their freighter. A bit hard to understand......
