If you wish to settle permanently in New Zealand you will need to apply for a Permanent Residence Visa or Permit.
There are different ways of applying for a Permanent Residence Visa or Permit:
Skilled, Business, Investor and Family Migration as well as Work to Residence.
The Skilled Migrant Category addresses applicants who are planning to take up skilled employment in New Zealand.
New Zealand's Business Immigration Policy consists of residence and temporary entry categories. Investor, Entrepreneur and Employees of Relocating Businesses Categories lead to residency in New Zealand, while the Long Term Business Visa Category allows temporary entry.
The objective of the Investor Category is to attract skilled business people with capital to invest in New Zealand.
If members of your family are already residing in New Zealand and you wish to join them, a Residence Application under the Family Category might be an option for you.
The objective of the Residence from Work Category is to enable the grant of residence to people whose talents are needed by New Zealand employers, people with exceptional talent in a field of art, culture or sport and people working in areas of identified absolute occupational shortage in New Zealand (Long term skill shortage list).
