For those that aren't aware Air NZ holds a charity auction each December to raise money for NZ Kids - this year Make a Wish Foundation and Kids Restore NZ Project.
Some of the items you can bid on include Jump Seat Rides, Boeing Factory VIP Tours, Simulator rised along with a whole heap of holiday items (including J Class travel, Airpoints $$ etc).
Well worth a look at

I don't have anything to do with Air NZ or the Auction however it's a good cause and some interesting things to bid on for those who aren't lucky enough to enjoy regular behind the scenes access to airlines.
Happy bidding!
