Think carefully how much debt you will incur. Unless your parents can help, most out of Massey end up with student loans in excess of 100k. If you want to leave NZ to find that first job, (and it's a good chance you will), then you're charged 6% interest on that. That's a big chain tethering you to NZ and its relatively small G.A. market.
Then again, massive crippling student loan debt probably is not a deterrent for the average 18 year old, or Massey wouldn't have any students.
