After reading a number of reports from various websites it seems that the large majority of customers disagree with your comments about poor service on Air NZ.
From what I gather you seem to step on Air NZ with the intent of looking for the negatives. Guess what? Flying on QF is no picnic. They've just managed to draw our attention away from surly F/A's and groundstaff by installing PTV's etc.
Finally, why do you care how Air NZ perform? You seem to have it in for them from the start. Fly QF to ENZED if Air NZ is such a horror.
