For those of you traveling to New Zealand within the next few days to attend or participate in the World Wheelchair Games should take note of the Air New Zealand flight restrictions of carry-on baggage for the domestic part of your trip.  Their weight & size restrictions are lighter and smaller than what you would be accustomed to when flying throughout North America, so if you've had warnings before for your typical carry-on bag domestically, then lighten it up considerably before (at least) the final leg of your upcoming trip to Christchurch.
