Virgin maintains its 73 fleet in NZ. When an aircraft comes back from there we don't see the same quality (or lack of) as we do with aircraft that return from Asia.
The ALAEA is not happy with Virgin maintaining anything in Asia. The difference between them and Qantas is this. Qantas had it all in Australia, HM facilities, staff, workshops, experience and apprentices. Virgin started with nothing.
Virgin are increasing staff and building to a point where in a few years time they will possibly be able to do HM here. You cannot snap your fingers and just do this when you started with nothing. On the other hand Qantas are dismantling everything even when it is done here cheaper. They are moving one way, Virgin are heading the other.
