Just heard on ZM newsbeat that Air NZ's first one arrives today but the best I could find on google is a twitter post saying the hand-over is today. But if it is enroute then I'm picking it will do a low fly over Auckland on the way to AKL.
Will mean the end of an era for the 747 as they are being replaced for the 777-300 (and 787 when they arrive one day)
