There are two paths you can go by

Got my First. Phew.

In principle, I could now complete a Masters in one year at Vic, enter directly into a PhD program at any New Zealand university, or start grad school from scratch in the USA (after passing the GRE, of course). Note that I'm not saying any of these is a good idea. They're just what the rules would allow me to do.

The alternative is to take up a permanent position at a well-respected New Zealand economic institution, continue my education informally, be productive, get paid, and take some control of my life.
