Hi Stan,
what do you mean by 'completed my requirements for PTNZ registration' ?
There is
a) PNZ (Physiotherapy New Zealand); this is the Professional Physiotherapy Association of New Zealand. As far as I know you need to be a registered Physio in NZ in order to gain membership. It is not compulsory in NZ for Physios to be members. Getting membership is easy, you apply, pay the fees and that's that. You can do that online - anytime.
b) PTBNZ (Physiotherapy Board of New Zealand); this is the quality authority which deals with registration of Physiotherapists (= professional licence) in NZ. This is a lengthy process for foreigners - if you haven't applied for registration yet - do it as soon as possible - it can take months.
Cheers,
Fyzzio
