I just had a look at the website, and it does have 'New Zealand university' in bold, which seems strange, I would think they would take graduates with overseas degrees though. I'm pretty sure there is at least one in my year. But I would probably check with the administrations office just in case. I know in terms of fees, that you are classed as a local, and only pay as much as any NZer.
Not too sure about the GPA thing either. But my interpretation is that 6.0 is across the entire degree. If you pass that test, then they only rank you on your last 2 years. Its sort of analogous to undergrad entry, where you have to get B+ across 8 papers, but once you get that, only 4 are used in the end for ranking.
You mean the MH03? Thats pretty important, I'd put a bit of effort into that. Thats the only thing that the interviewers get to see before the interview, so a good MH03 will give them a good impression of you even before you walk in. They use the MH03 to base some of their questions on, so its a good way to direct them to things you want asked about.
