Hi,
in NZ you apply for registration. The fee is NZ$1226,-. Your degree, other studies and work experience will be assessed and a decision will be made whether you get registered or not. It's all done on an individual basis.

The Physiotherapy Board of New Zealand > Registration - Overseas Qualified Physiotherapists

The website has information on the 10 competencies you have to meet and full guidelines on how to compile your portfolio.
Good luck,
Fyzzio
