I should have read the reviews here before booking the cruise, but there weren't too many affordable New Zealand cruises that left when we needed.
About 80% of this cruise was booked by senior citizens, which in and of itself isn't a terrible thing, but as 20-somethings, it did become a bit frustrating when disembarking at various ports, going through buffet lines, or really doing anything where speed and efficiency would be nice. The shows were designed for the older set (much older), which was understandable. But if they're going to call a production show a "tribute to the music of recent decades," at least choose more than 2 songs created after 1970, or rename the description. Frank Sinatra is definitely not a "recent" musical talent.
As far as service, I don't know if it's because Aussies don't tip, but I felt barely tolerated by Princess staff. Our stateroom steward was very nice, but nobody else went out of their way to amaze us. I was even scolded by one person for trying to take my food to my stateroom.
Our cabin was actually pretty nice, but my brother's cabin just two doors down was right above one of the lounges and they complained about noise.
