I completed a Master of Arts degree in Media Studies at Victoria University of Wellington and it was a fantastic experience which has irrevocably changed the direction of my life and forced me to reassess my values.
The University is large, but the relatively small size of the campus and the city of Wellington makes it feel like you aren't totally lost in the crowd. I experienced some health challenges while studying and everybody was incredibly helpful during that experience. I was able to make changes to my visa, file multiple complicated insurance claims, and work with my professors to adjust deadlines and academic expectations. This was a stressful time made easier by these people.
My academic program required a lot of research and the library and my professors were real assets in helping me get through it. If you do come to VUW for graduate work I'd recommend contacting your professors ahead of time to state your interests and passions, people are really relaxed and welcome proactive outreach students.
As far as lifestyle, Wellington and New Zealand are second to none. I became hooked on the super strong coffee, endless variety of outdoor activities, and the laid back attitude of Wellington. One thing which was not so great was housing. New Zealand houses are often not insulated, which sounds barbaric to people from colder climates like myself. It can be hard to find a house that is suitable, so once you decide to go to New Zealand look early and use social media to find good places. Cost of living is often complained about, but I found if you are a bit flexible with what you eat/purchase you can get by pretty easily (I'm also from a more expensive area of the U.S. so take my comments with a grain of salt).
I have absolutely no regrets about coming to Victoria, and I'm happy to answer any questions about it. I'm still in constant contact with friends I made there and New Zealand will never leave me, which is really awesome.
