Presence in New Zealand: you need to show you have been physically present in New Zealand for a certain amount of time and that you plan to stay living in New Zealand.
Language requirements: you need to be able to hold a basic conversation in English, like shopping or banking without assistance.
Good character: if you have never been in trouble with the law in New Zealand or overseas, you meet this requirement.
The Department of Internal Affairs (DIA) has a self-check tool to find out if you are eligible for New Zealand citizenship. To see if you are likely to meet the requirements and to check whether you can apply online, visit the Govt.nz website.
