Good grief, now we're going down the "I've paid taxes all my life therefore the government OWES me superannuation" route with "I've invested in Air NZ and spend heaps of money on fares so they owe MY refund".

Absolutely deluded, I think there is no way of getting through to you self entitled frequent fliers. Try take a leaf out of JFKs book - ask not what Air NZ can do for you; ask what you can do for Air NZ.
