Interestingly, 'decent compensation' for us could involve a simple re-route directly to CHC given that we have nested one-ways on QF for AKL-CHC. (Decided to spend all our time on the south island!) Of course, from the experiences others have had with the UA CNZ fare concerning voluntary or involuntary changes, I'd actually be afraid to accept a re-route for fear it might cause UA to invalidate the itin. This is really one of those situations where it would seem mutually beneficial for ANZ to send us straight to CHC so that a.) they can sell more C seats, and b.) we can cut off a leg of our journey. But somehow I'm guessing the UA goons would never see it that way....
