Just to compare: 2 award tickets in C to AKL with M&M are 370k (plus fees and taxes).
I second this. Besides being (almost) impossible to find seats it would not make sense to use this amount of miles on this. Just book a regular I class ticket (if you can find availabilty) - or book a discounted revenue C class ticket.
