Hi Trina Ferrer,
You need to be registered in New Zealand before you can work as physiotherapist, one advantage is that you need not take the exam while on the other hand you have to look at their competency charts which drove a lot of people up the wall including me hahaha!!!
goodluck to you!!!
Kindly look into this website: http://www.physioboard.org.nz/registration_nz.asp
