Adoption Records New Zealand: How to Access Your Birth Information
If you were adopted in New Zealand, you have legal rights to information about your origins — but those rights depend on when your adoption took place and what records were kept. This post covers what you can access, how to apply, and what limits exist.
The Adult Adoption Information Act 1985
The Adult Adoption Information Act 1985 was a turning-point piece of legislation. Before it, adopted people had no legal right to know who their birth parents were. The 1955 Adoption Act's "clean break" model treated original identities as sealed permanently.
The 1985 Act changed this by giving adopted people who have turned 20 the legal right to apply for their pre-adoptive birth certificate — the original certificate that records the birth parents' names, before the legal adoption erased that information.
This certificate typically contains:
- The birth mother's name, age, and birthplace
- The birth father's name, if it was recorded at the original registration
- The date and place of birth
- The court that made the adoption order
The application costs $15.30 and is made through the Department of Internal Affairs (births.deaths.marriages.govt.nz).
The Veto System — and Why It Only Applies to Pre-1986 Adoptions
The 1985 Act introduced a veto mechanism to protect birth parents who expected permanent confidentiality under the old system.
Vetoes only apply to adoptions that occurred before 1 March 1986.
If your adoption was finalised before that date, a birth parent may have placed a veto on the release of their identifying information. In practice, this means the pre-adoptive birth certificate is still issued — but the identifying details of the parent who placed the veto are removed.
Vetoes expire after 10 years and must be actively renewed. If a veto was placed in 1986 and never renewed, it has long since lapsed.
For adoptions after 1 March 1986: No vetoes are permitted. Full access to the original birth certificate is an unconditional right once you turn 20.
What If You Want More Than the Birth Certificate?
The pre-adoptive birth certificate gives you names and dates. It does not give you:
- Social worker reports from the time of adoption
- Reasons why the birth parent placed the child for adoption
- Medical or health history information
- Information about siblings
To access the full adoption file — including social worker reports and other documentation held by the Ministry of Justice — you need to make a Section 23 application to the Family Court. This is not automatically granted. The court considers whether there are compelling reasons to release the information and weighs that against any privacy interests.
For medical history (such as genetic health risks), Oranga Tamariki's search and reunion service may be able to assist in obtaining non-identifying health information from birth family members without revealing your identity or theirs.

Oranga Tamariki's Search and Reunion Service
Oranga Tamariki provides a dedicated search and reunion service for adoptees, birth parents, and other birth relatives.
What the service provides:
- An intermediary service where a social worker makes first contact on your behalf, rather than you approaching the birth parent directly
- Counselling to help manage the emotions involved — both before the search and after contact is made
- Support if contact is refused or if the reunion is difficult
This matters because reunion is not always what people imagine. Some birth parents feel guilt, grief, or conflict. Some adoptees encounter rejection. Having a social worker manage the first contact significantly reduces the risk of the encounter going badly.
To access the service, contact Oranga Tamariki's National Office (orangatamariki.govt.nz) and ask to speak with an adoption social worker in the Post-Adoption and Information team.
For Birth Parents
Birth parents also have rights under the 1985 Act. Once an adopted person turns 20, a birth parent can apply for identifying information about the adopted person — subject to any vetoes placed by the adoptee.
If you placed a child for adoption and want to make contact or provide updated health information, Oranga Tamariki's reunion service can help you do this through the intermediary process.
DNA Registries and Other Search Tools
Many New Zealand adoptees now use commercial DNA testing (23andMe, AncestryDNA) to find biological relatives, independent of the legal records system. This can be particularly useful for:
- People whose birth father was not named on the original registration
- People whose pre-1986 adoptions are subject to vetoes
- People searching for siblings or extended family rather than birth parents
DNA databases do not require anyone's consent to share a match — you simply upload your results and see who else in the database shares your DNA. This has become the fastest practical route to finding biological family for many adoptees.
Accessing Records for Overseas Adoptees
If you were adopted from overseas and brought to New Zealand, your original records are held in the sending country — not in New Zealand. Oranga Tamariki may be able to assist in contacting the relevant overseas authority, but access depends entirely on that country's laws.
For the reverse situation — New Zealanders who were adopted overseas as children and are now adults — the same principle applies: the records are held in the country where the adoption occurred.
What Adoptive Parents Should Know
The rights described in this post belong to adopted people once they turn 20, and to birth parents. Adoptive parents do not have a legal right to suppress access to records or block reunion under the 1985 Act.
Modern adoption practice expects adoptive parents to actively support their child's right to understand their origins. This starts well before age 20 — building an adoption story the child is familiar with, keeping letters and photos from birth families, and being honest about the circumstances of adoption from an early age.
The New Zealand Adoption Process Guide covers how to approach identity conversations with adopted children and what records you can preserve during the adoption process to help them later.
