Qantas Jetconnect - The NZ (cost saving) version of QF (so I was told by one of the F/A's).
They operate the 733 and 734 both internally and across the ditch from NZ.
regos are: 733: ZK- JNB/JNC/JND/JNN/JNO
734: ZK- JTP/JTQ/JTR
All expat QF.
Hope that cleared it up
Edit: Can all be found in link above!
