Looking to register to work in NZ...how?!

Can anyone tell me how I go about registering to work as a physiotherapist in New Zealand, is it the same as working in Oz, I would prefer to work in NZ but not sure where to look or who to speak to regarding what to do!

If anyone could help please email me at [email protected] as soon as possible, myself and my fiancee are both chartered and state registered physiotherapists currently working in the UK.

Please help!!!
