Open Adoption New Zealand: How It Works and Why the Agreements Aren't Enforced

If you're pursuing domestic adoption in New Zealand, open adoption is the default. It's not a special category or an optional arrangement — it's the model that Oranga Tamariki expects, and it's the model that modern child development research supports.

But there's a catch that surprises many families: open adoption agreements in New Zealand are not legally enforceable.

What "Open Adoption" Means in Practice

An open adoption is one where the birth family and adoptive family maintain some form of ongoing contact after the adoption order is made. This can range from:

• Letterbox contact: The adoptive family sends annual updates, photos, and letters to a mailbox managed by Oranga Tamariki, which are forwarded to the birth parent. The birth parent may (or may not) respond in kind. This is the most common form of contact.
• Direct contact: Email, phone, or face-to-face visits agreed between both families. This happens in some placements, particularly when birth parents and adoptive parents have built a genuine relationship before and after birth.

There is no fixed formula. The contact arrangement is negotiated between the birth and adoptive families at the time of placement, usually facilitated by the Oranga Tamariki social worker.

Why Contact Agreements Cannot Be Enforced

Once the Family Court makes a Final Adoption Order, the adoptive parents become the child's full legal parents. They have absolute parental authority.

The Adoption Act 1955 contains no mechanism for enforcing contact between an adopted child and their birth family. If the adoptive parents decide — six months or six years after the adoption — to reduce or stop contact entirely, the birth parents have virtually no legal recourse through the Family Court.

This is a deliberate (if controversial) feature of the Act's "clean break" design. In the 1955 framework, the child belonged completely to the adoptive family. There was no legal space for ongoing relationships with birth family.

Modern practice has evolved far beyond this framework, but the law has not caught up. Oranga Tamariki's social workers work hard to build goodwill and mutual commitment to contact between families before the adoption is finalised — because goodwill is all that underpins the agreement once the order is made.

What This Means for Birth Parents

If you are a birth parent considering adoption, you should understand that any contact arrangement you agree to rests on the adoptive parents' willingness to honour it. You cannot take them to court if they stop responding to letterbox updates or end visits.

This is why Oranga Tamariki takes the selection process seriously. Birth parents are encouraged to spend time with the adoptive family before making their decision — getting to know them, assessing their genuine commitment to openness, not just their stated intentions in a profile.

The Ministry also encourages birth parents to ask direct questions: "What will you tell our child about me? How often will you send updates? How will you explain the adoption?" The answers to these questions, and the relationship built before birth, are the only real guarantees you have.

What This Means for Adoptive Parents

The lack of legal enforcement cuts both ways. It also means that if you agree to contact and later feel it is not serving your child's wellbeing, you have legal authority to modify or end the arrangement.

But consider what the research shows: adoptees who have access to their birth family history, and who grow up knowing they are not "rejected" but rather "chosen" by their birth parents in difficult circumstances, generally have better long-term identity development and psychological wellbeing. Contact — even annual letterbox contact — serves the child's interests, not just the birth parent's.

Oranga Tamariki's home study assessment specifically probes your views on openness. Social workers are looking for evidence that you genuinely embrace the idea of your child having a birth family connection — not that you're tolerating it or paying lip service to it to get through the assessment.

The Reform Gap

Adoption Action NZ and the Law Commission have repeatedly highlighted the lack of legally enforceable contact agreements as a major deficiency in New Zealand adoption law. Multiple countries — including Australia and the UK — have moved to enforceable open adoption contact frameworks.

New Zealand has not. The 2021–2022 Ministry of Justice consultation on adoption law reform identified enforceable contact as a priority issue, but a comprehensive new Adoption Act has not yet been introduced.

Until the law changes, contact agreements remain relational contracts — upheld by trust, not by courts.

Starting an Honest Conversation

If you're a prospective adoptive parent preparing for the home study, think carefully about what you genuinely believe about open adoption — not what you think the social worker wants to hear.

If you have real reservations about maintaining contact with a birth parent who made difficult life choices, those reservations won't disappear after the adoption is finalised. Working through them honestly during the assessment — with the support of a social worker who has seen these dynamics play out — is far better than discovering those reservations after a child is placed.

The New Zealand Adoption Process Guide covers how to approach the home study assessment honestly, including the contact and openness questions that social workers most commonly use to evaluate applicants.
