Most have probably picked up on this but I moved to NZ and did mine at Mainland back in 2005.
One thing to remember is that they get calls and emails from 'timewasters' all day everyday.
I moved to NZ (Granted, I had rellies there) before any of the courses accepted me. A show of commitment goes a long, long way!
Regardless of your nationality, if you are entitled to a loan AND CURRENTLY IN NZ, you WILL find a position on one of these courses.
