Hi Monty James
You would be very welcome to come and work and study here. You'll love it. For a small country we have a well developed tradition of physiotherapy and a high standard of practice. We have two world class universities with great post grad musculolskeletal programmes. Have a look at University of Otago (based in Dunedin with outposts in Christchurch and Dunedin and Auckland University of Technology physothearpy school websites
Getting through the gate is a bit difficult for if you completed with a three year degree course - The NZ physio board is very stickly about this but it is just a matter of jumping through the hoops and you'll be in.
NZ physios enjoy good recognition throughout the English speaking world so I think you would find any work experience and further education you did hear would only put you on a higher footing.
Unfortunately our jobs aren't always the most lucrative - that really reflects that our country such a small economy in NZ. However the lifestyle opportunities are great! Why not get registration here then try a few locums to see what you like. Or you could just enrol in one of our courses straight off. If you like bigger cities go to AUT; if you like the idea of a small university town with a fantastic student feel, and great access to the outdoors come Otago.
Go for it!
