If you have a job offer from an accredited employer in New Zealand, you could apply for a work visa under the accredited employer policy.

To be granted a visa, you will need meet several requirements including the qualification/work experience requirement. You will need to meet the qualification/work experience requirement specified in the advertisement that was used in the employer’s application to recruit non-New Zealanders. Credible documents in support of the work experience should be provided with the application.

The other requirements that you should meet is the health and character requirements. There is no English requirement. There is also no upper age limit. There is also no limit as to how many times you could renew your visas. You could also qualify for residence if you meet the relevant residence criteria.

Usually, you will receive three years work visa. In some cases, work visas are granted for two years and with a stand-down period to be satisfied before you can apply for another visa unless you can meet the median-wage requirement in the next application. 

Getting legal advice could be useful especially if your aim to become a New Zealand resident.
