Start by identifying the records and rules that apply
The Adult Adoption Information Act has important 1986 commencement points. A court file, pre-adoptive birth record and Oranga Tamariki file are separate, and the birth father's name may not appear on the original registration.
People overseas can begin through the published New Zealand government process. Pre-1986 counselling arrangements, identity evidence and overseas delivery should be confirmed at the time of application.
Check the current procedure before applyingThis guide explains the likely process, but forms, contact details, eligibility and access rules can change. Check the linked source before sending identity documents or paying a fee.
Choose the situation that describes you
Adopted in New Zealand
What applies: Identify the date, place and legal form of the adoption in New Zealand before choosing a records process.
How to look for records: Start with the pre-adoptive birth certificate process, then request the Oranga Tamariki adoption file and identify the court record separately. Ask whether the person was born and adopted in New Zealand and whether the adoption occurred before 1 March 1986.
How to look for family: An adopted person generally has access to birth parent information from age 20. For adoptions before 1 March 1986, counselling and a possible historic veto must be checked; later cases can normally proceed directly. Births, Deaths and Marriages supplies the pre-adoptive birth certificate, Oranga Tamariki holds its adoption records, and court records are a separate holding.
Important: Access to one repository does not provide the whole file; apply the rules for the relevant date and place.
Born in New Zealand and brought to the UK to be adopted
What applies: Establish whether the operative order was made in New Zealand, in the UK, or both.
How to look for records: Start with the pre-adoptive birth certificate process, then request the Oranga Tamariki adoption file and identify the court record separately. Ask whether the person was born and adopted in New Zealand and whether the adoption occurred before 1 March 1986. Separately obtain the UK immigration, receiving-agency, court and adoption records.
How to look for family: An adopted person generally has access to birth parent information from age 20.

Births, Deaths and Marriages supplies the pre-adoptive birth certificate, Oranga Tamariki holds its adoption records, and court records are a separate holding.
Important: Origin-country and UK records are separate; do not infer recognition or finalisation from nationality alone.
One parent was from New Zealand
What applies: Do not use an adoption record process merely because a parent was from New Zealand; start with the parent's verified identity and locality.
How to look for records: Use civil registration, archives and genealogy after obtaining the strongest available name, date and place.
How to look for family: An adopted person generally has access to birth parent information from age 20.

Important: A parent's nationality does not itself create access to another person's adoption or civil records.
Records and family finding
Start with records
Start with the pre-adoptive birth certificate process, then request the Oranga Tamariki adoption file and identify the court record separately. Ask whether the person was born and adopted in New Zealand and whether the adoption occurred before 1 March 1986.

DNA
Use DNA as a separate source of evidence, not as proof by itself. Corroborate matches through shared match analysis, family trees and documentary evidence, and consider privacy and unexpected discoveries before testing.
Peer support
Official records processs should come first. Peer, Māori whakapapa and intercountry-adoptee organisations may help with support or family connection, but authority, tikanga, consent and current eligibility must be respected.
Practical next steps
If you have no namesApply for the pre-adoptive birth certificate and ask Oranga Tamariki for the adoption file, stating the adoption date and whether you live overseas.
If you have a name or placeUse the verified name and locality with civil registration, archives and electoral or genealogy records, while using Oranga Tamariki for supported contact where appropriate.
If the search has stalledCheck for a pre-1986 veto, missing paternity registration or a separate court holding. Ask each record holder for a written explanation, then use genealogy and DNA only as corroborating procedures.
Verified sources and resources
