Long haul flight. Would have helped if they gave the both boarding passes, ie include connection- all within the international transit area in Auckland (ie home base) ... all my other recent (non AIR NZ) long haul flights companies managed to do achieve this smoothness...AIR NZ office was shut in very early hours of arrival. Not useful. However: Overall decent experience.
