Becoming an official citizen of New Zealand allows you to vote in elections and apply for a New Zealand passport. The country has rather stringent citizenship requirements which include having been a resident for at least five years and providing proof of good character.
Study the New Zealand requirements for receiving a grant for citizenship (See Resources 1). Individuals who have a least one parent who was a citizen at the time of the child's birth are eligible to apply for citizenship, as are those who marry a New Zealand citizen. Others must live in the country for at least five years, with the exception of those who live with a New Zealand partner which allows them to apply for citizenship after only two years of residency. Residency requirements in New Zealand are also quite strict, requiring applicants to prove good health, character and sufficient income (See Resources 2).
Apply for the grant of New Zealand citizenship by filling out the application form (See Resources 3). You will need to provide credit card information in order to pay the application fee, which is presently $460 for an adult and $230 for any child under the age of 16.
Fill out the rest of the application form, including your name, residential address, parent and family information, intentions, means of support and all other required field that apply to you.
Send your completed form to the citizenship office (See Resources 4). Make sure that you include your fee payment, photographs and all other required documents as stated in the application form. When you application is accepted you will receive a letter in the mail telling you when you can attend the public citizenship ceremony.
Attend the public citizenship ceremony where, if you are over the age of 14, you will have to pledge your allegiance to the Queen of New Zealand. During the ceremony you will receive a certificate of New Zealand citizenship.
