Hi,
not quite sure what you mean - you should have tried to register a few years back - that was a pain.
Have you looked at the Physioboard's website?
There are templates and an application guideline document. Not really that difficult to follow.
Competencies are very similar to KSF strandards.

And as to fees: that info comes up when you click on 'registration/ overseas process' on their website. It's NZ$1226.

Good luck,
Fyzzio
