I did my CPL/IR at the International Aviation Academy of New Zealand at Christchurch. Good a/c, good instructors, great place to fly.
As evereybody has said, there are v few jobs availalbe, despite there being a larger GA scene in NZ than the UK.
What I did save, due to lower costs in NZ, I had to spend in the UK to transfer it all to the CAA/JAR system.
It's a great learning experience, but puts you out of the UK scene for a number of years when you really need to be looking around for work.
