viewsonic, by the time a 2016-hire SO gets senior enough to get near a 777 window seat there won't be a 777. Both widebodies will one day be replaced by a single type, but don't hold your breath for that one. Yes it is quite normal for 777 SOs to move to Aus based 737s, especially now the E190 is going. No one is forced to go to NZ, it's just a quicker path to 737.
