There some glitches with the gift register - I have 3 household family members with duplicate profiles. One profile is fully populated, the other is not. The non-household giftees usually have incomplete profiles despite entering the necessary information.
Also, it not possible to edit giftees, you can only delete them and re-add them. This really seems a poor implementation of the 'manage giftees' page (any coders - you can advises why AirNZ might not allow editing?) I needed to delete and add one household giftee as his un-populated duplicate profile kept coming up as the only option on the drop-down for the partner award portal....
