To add to this looking at the fare guide and rules both J and V are used for Australian connections. J can be used for business on Qantas when there is availability - if there is no availability you'll be booked into V.
The price is the same for AKL-SYD-PER regardless of whether you're booked into J or V.
The Air NZ website says if you're booked into V and says you'll have economy on the QF flight. If you're booked in J there is no mention of this.
