It is really difficult to get a job as a RN in NZ at the moment. Only 65% of new grad nurses this year found jobs on a new grad programme. However once you have some experience it is much easyer. To employe a forigen nurse the employer must prove that a NZ nurse isnt capable to filling the role. Hence if you have experince you will be more employable. Wellington is a really nice NZ City , Auckland is a city and living there you could be anywhere in the world. I would suggest Wellington is a nice choice.
