Air New Zealand.

A couple of months ago we received notice that our 11/29/07 ANZ flight from LAX had changed from 7:45 pm to 8:00 pm.
Over the weekend we received another e-mail notice but can't open it. When I went to ANZ site it does show the 2nd flight (NZ2) has been changed to something like 9:30 pm, but not the 1st flight (NZ1) It still shows 8:00 pm
Did anybody else receive this notice?
