Hi there,
You can check your eligibility against the criteria given on the New Zealand Physiotherapy Board's website. If you think your degree meets all the criteria, you can fill out your application and send it to them to assess.
Their assessment is very subjective and they do not have a one-size-fits-all assessment for applications.
Once you read their eligibility criteria, you should have a pretty good idea whether your degree and curriculum has the necessary material required to meet it.
Hope this helps. Let me know if you need further assistance.

Kind regards.
