New Zealand Citizenship by Descent
At a glance
New Zealand citizenship by descent is for people born outside the Realm of New Zealand to a parent who was a New Zealand citizen by birth or grant. It generally has a one-generation limit, so a parent who was only a citizen by descent may not be enough.

Summary
Citizenship by descent is usually available to a person born outside New Zealand whose parent was a New Zealand citizen otherwise than by descent when the person was born. “Otherwise than by descent” normally means the parent was a citizen by birth or by grant.
The status must be registered with the Department of Internal Affairs (DIA) before the person can obtain a citizenship certificate or New Zealand passport. Older births and unusual acquisition histories can have different rules.
Eligibility
For a person born overseas on or after 1 January 1978, the usual test is:
- the applicant was born outside New Zealand; and
- at least one parent was a New Zealand citizen otherwise than by descent at the time of the birth.
The evidence normally includes the applicant's full birth record, identity document, and the claim parent's New Zealand birth certificate, citizenship certificate, or other proof of citizenship and parentage. Adoption, assisted reproduction, surrogacy, name changes, or a parent whose citizenship status was confirmed later can require additional records.
If you were born before 1 January 1978, a different process applies. Contact DIA's Citizenship Office before applying to find out which rules and form apply to your case. DIA may need to consider the law in force when you were born, which parent was the New Zealand citizen, whether your parents were married, and whether later changes to the law affect your claim.
A parent who was only a citizen by descent normally cannot transmit descent to a child also born overseas. A grant under section 7A of the Citizenship (Western Samoa) Act 1982 is also expressly excluded as a transmitting status for a child born outside New Zealand.
What This Route Allows
Once registered, the person receives proof of New Zealand citizenship and may apply for a New Zealand passport. Citizenship itself does not expire and New Zealand permits dual or multiple citizenship, subject to the other country's law.
A citizen by descent has the same core citizenship status as other citizens, but there is an important transmission limit. A child born in New Zealand to that citizen is normally a citizen by birth; a child born overseas normally will not acquire New Zealand citizenship through that parent alone.
A citizen by descent who later meets the residence and other requirements may apply for citizenship by grant. If granted, they become a citizen otherwise than by descent and can normally transmit citizenship to future overseas-born children.
What This Route Is Not
It is not a general ancestry route through any New Zealand grandparent. A grandparent can be relevant only if the intervening parent had a status capable of transmitting citizenship when the applicant was born.
Registration is also not a substitute for proving the legal parent-child link. DNA, family stories, or a passport held by a relative may help explain a case but do not replace the civil and citizenship records DIA requires.
Next Steps
- Build a dated family line showing the applicant's birth and the claim parent's citizenship status on that date.
- Obtain full birth, adoption, marriage, name-change, and citizenship records as relevant.
- Confirm whether the parent was a citizen by birth, grant, descent, or a special Western Samoa grant.
- For a birth before 1978 or an unusual parentage case, ask DIA which historical provision and form apply before filing.
- Register citizenship by descent and, if wanted, use the combined process to request a passport.
