Living permanent in new zealand

If you are presently in NZ no you cannot extend your stay.

Go online to www.immigration.govt.nz for visa information This site will tell you how to go about getting a work visa and applying for PR.

But visas are issued on a points system. The more qualifications you have the more points you gain. 

There is a list of skilled trades that the country needs.

We have been looking and traveling for some time  with the goal of retirement. May I suggest an excellent website for possible New Zealand Expats: www.enz.org has a wealth of information -- not only good blogs, but also extremely helpful people on its forum. I've been reading a lot of back-and-forth reading about periodic leaving and returning to NZ, getting sponsors, coming in with a valuable skill, etc.  NZ is one of those countries that assigns a numeric "value" to anybody wanting entrance,  Perhaps being from S. Africa may help.  Good luck!

I am from Mauritius island and dream of adventuring to a country like N zealand. I am a 47 yr married , Medical imaging Technologist in Mauritius. I have worked as a Radiographer for almost 26 yrs now.Mainly at the Angiography dept , CT and general Radiography. My wife is a primary school teacher. Will there be any scope for me to immigrate to N zealand ? I know I have to register , and then apply for my PR .
Thanking you
