What are the requirements for an American to become a nurse in New Zealand?

I'm an American citizen and I'm planning on becoming a nurse (not sure about whether I'll be RN or NP though). I've considered moving to New Zealand someday, probably a few years after finishing school. What requirements will I have to fulfill to be able to become a nurse in New Zealand once I already have proper training for the US? Tests, more school, etc...? Thanks for any information!

contact the new zealand government and there
