Do I need to hold a visa to apply for registration?
No, you do not need to hold a visa to apply for registration.
Immigration is an entirely separate issue to registration which you will need to satisfy before you work in New Zealand.
The Physiotherapy Board of Aotearoa | New Zealand can only provide answers to queries about registration in Aotearoa | New Zealand.
Any enquiries about visas or other immigration matters need to be directed to Immigration New Zealand.
