New Zealand Citizenship by Descent

Summary

New Zealand citizenship by descent is available to people born outside the Realm of New Zealand to a parent who was a New Zealand citizen by birth or by grant. The rule stops one generation deep — if your New Zealand parent was themselves a citizen by descent (born abroad to a New Zealand grandparent), your line ends there.

Because New Zealand permits dual citizenship, Americans with a parent born in New Zealand, the Cook Islands, Niue, or Tokelau — or a parent who naturalised as a New Zealander — can register as citizens, obtain a New Zealand passport, and keep their US citizenship.

Eligibility

• At least one parent was a New Zealand citizen at the moment of your birth. "New Zealand citizen" includes the Cook Islands, Niue, Tokelau, and the Ross Dependency before 2006.
• Your New Zealand parent's citizenship route was birth or grant. Citizens by descent cannot pass citizenship on to their own children born abroad. You need to confirm how your parent became a citizen:
  • By birth — they were born in the Realm of New Zealand before 2006, or in the Realm after 2006 to a NZ-citizen or NZ-resident parent. ✅ Eligible
  • By grant — they were naturalized, typically after 5 years of NZ residence. ✅ Eligible
  • By descent — they were born abroad to a New Zealand parent. ❌ This route stops.

What if your New Zealand parent was a citizen by descent?

Unfortunately, there is no descent route for you. However, two alternatives exist:

• If you later move to New Zealand yourself and become a citizen by grant (5 years residence), you can then pass citizenship to your own children.
• If your parent was physically present in New Zealand for a meaningful period and obtained a Confirmation of Citizenship by Descent before your birth, it doesn't change the rule — the one-generation limit still applies.

Dual-citizenship note for Americans

New Zealand has no objection to dual citizenship, and the US does not require Americans to renounce foreign citizenship. The US oath of allegiance has language that sounds like renunciation, but US practice and case law allow dual citizenship. Americans registering as New Zealand citizens by descent keep their US passports.

What This Route Allows

This route can help confirm or document citizenship in New Zealand when the citizenship-creating facts named above are proven. For many people in this category, the main work is evidence: civil records, family-link records, prior citizenship records, and any registration or restoration paperwork needed to show the claim.

What This Route Is Not

This is not a shortcut around documentation. Even when the citizenship claim is based on a right, you still need records that prove each required fact and family link.

Application Process

Documentation

• Your birth certificate showing both parents.
• Proof of your New Zealand parent's citizenship at the time of your birth:
  • Their New Zealand birth certificate (if born in NZ/Cook Islands/Niue/Tokelau before 2006), or
  • Their New Zealand citizenship certificate (if naturalized), or
  • A New Zealand passport issued before or on your date of birth.
• Proof of your parent's citizenship route — critical for confirming you're not descending from another descent-citizen.
• Your current passport (US, UK, etc.) for identity.
• Marriage certificates for any name changes.
• Two passport-sized photos for the citizenship certificate.
• A New Zealand citizen who has known you for at least 12 months as an identity witness, plus their passport details (they complete form BDM47).

Fees

• Registration of citizenship by descent: NZD 275 (adult, 2026 rate).
• Combined with adult passport: from NZD 387.
• Review: straightforward cases turn mainly on the parent-child documents and your parent's citizenship route.

Filing

• Online via RealMe (recommended if you have a RealMe account).
• By mail on form BDM47 to the Department of Internal Affairs in Wellington, or via a New Zealand consulate abroad.

The US does not have a dedicated New Zealand consular presence for citizenship — the New Zealand Embassy in Washington DC and consulates in New York, Honolulu, and Los Angeles handle identity witnessing and document certification.

Next Steps

1. Confirm your parent's citizenship route — birth, grant, or descent. Obtain their NZ birth certificate or citizenship certificate.
2. Order your own birth certificate from the country you were born in.
3. Find a New Zealand citizen who has known you for 12+ months to act as your identity witness.
4. Complete BDM47 (online or paper) with your supporting documents.
5. Pay the NZD 275 fee (add passport fee if applying for passport concurrently).
6. Wait for your citizenship certificate and respond promptly to any request for missing documents.
7. Apply for your New Zealand passport once citizenship is confirmed.
8. Children born to you after your registration: remember you cannot pass NZ citizenship to children born abroad. If you want them to be NZ citizens, either have the child in New Zealand or move there and naturalize.
