with the NZ physio board and i must say they were not particularly helpful!!
You probably mean that they were helpful, but wouldn't tweak their rules for you....

Sorry, I don't think that anyone can help you guys, because -obviously- you are some of the first people going through the new process. However, it will be very helpful to learn later how you got on with it all.

The entry criteria have not changed: In NZ, Physios graduate with a 4 year BSc and you will have to show that your Physio programme is at equal standards. The British BSc is accepted, but since their programme is only 3 years long, you will have to prove that you have worked full-time as a Physiotherapist for at least 12 months (to make up for the missing year).
I don't know, what the programme for EU Physio is like. If you have done a BSc, then the same rules apply. Have you graduated with a diploma, then this will not be accepted.

The job of a Physio Assistant is not accepted, as it isn't Physiotherapy.

Good luck to all of you.
