i am from the same neck of the woods as you, am currently in china

my ticket was AKL-(SYD)-HKG, then a overland trip, CSX-PVG, PVG-(SYD)-AKL cost was 1480NZD per person on QF. Before i booked there was a another option i was looking at for AKL-HKG, CSX-PEK, PEK-AKL on a combination of AirNZ and AirChina going for about 1450NZD

your question is too open ended, need to know where you are going and when. we missed the busy period by a week (early in october it was school holidays in NZ/AUS as well as the mega golden week of china when national day matched up back to back with mid autumn festival) and flights were upwards of 1900-2000 for just return AKL-HKG

just play around on all the booking sites with your dates and destination
