Legal guardianship NZ refers to the legal rights and responsibilities to make significant, long-term decisions regarding a child’s upbringing, such as their education, medical treatment, religion, and name changes, under the Care of Children Act 2004. This role is distinct from day-to-day care, which pertains to the child’s daily living arrangements and routine supervision.
Understanding Legal Guardianship in New Zealand
In the realm of New Zealand family law, terminology is critical. Many parents and caregivers often use the terms “custody” and “guardianship” interchangeably, but legally, they represent two vastly different concepts under the Care of Children Act 2004. While one dictates where a child sleeps and who makes their school lunch, the other dictates the fundamental direction of the child’s life.
Legal guardianship is not about the amount of time you spend with a child; it is about the authority to participate in their development. A guardian is someone who is legally recognized as having the duty to contribute to the child’s intellectual, emotional, physical, and spiritual development. In New Zealand, most parents are guardians automatically, but this is not always the case.

Who is Automatically a Guardian?
Under current New Zealand law, the biological mother is automatically a legal guardian when the child is born. The father is also automatically a guardian if he was married to or in a civil union with the mother at any time during the pregnancy, or if he is listed on the child’s birth certificate (for children born on or after 1 July 2005). Partners of the mother who are not biological parents can also become guardians under specific circumstances involving assisted reproductive technology.
It is important to note that guardianship does not cease simply because a relationship ends. Even if parents separate, divorce, or live in different countries, they generally retain their guardianship rights and responsibilities unless a court orders otherwise. This creates a lifelong legal link between parents that requires ongoing cooperation regarding the child’s welfare.
Day-to-Day Care: What Used to Be Called Custody
Prior to the Care of Children Act 2004, New Zealand law used the terms “custody” and “access.” These terms were viewed as creating a sense of ownership over children. The modern legislation replaced these with “day-to-day care” and “contact.”
Day-to-day care refers to the practical, everyday reality of looking after a child. A person with day-to-day care is responsible for:
- Providing a home and safe sleeping environment.
- Ensuring the child is fed, clothed, and washed.
- Getting the child to school or daycare on time.
- Managing routine discipline and emotional support.
- Making minor medical decisions (e.g., administering paracetamol for a mild fever or applying a plaster to a scrape).
It is entirely possible for one parent to have sole day-to-day care (the child lives with them 100% of the time) while both parents remain legal guardians. In this scenario, the parent with day-to-day care manages the routine logistics, but they cannot unilaterally make major decisions about the child’s life without consulting the other guardian.
The Critical Difference: Strategic vs. Routine Decisions
The friction in many co-parenting relationships often stems from a misunderstanding of where day-to-day care ends and guardianship begins. To simplify: Day-to-day care is tactical; Guardianship is strategic.
A parent with day-to-day care does not need permission to choose what the child eats for dinner, what time they go to bed, or which friends they play with on the weekend. These are routine matters incidental to the care of the child.
However, guardianship rights are triggered whenever a decision has a long-term impact on the child’s well-being. If a decision is irreversible or significantly alters the child’s life path, it is a guardianship matter. Both guardians must consult and agree on these issues. If they cannot agree, the decision cannot be made unilaterally by the primary caregiver.
For authoritative information on these distinctions, the New Zealand Ministry of Justice provides extensive resources outlining the specific duties of guardians.
Specific Decisions Requiring Joint Guardian Consultation
Disputes often arise when one parent acts unilaterally on a guardianship matter. To ensure compliance with New Zealand law, you must consult all other guardians for the following decisions:

1. Place of Residence
You cannot simply move a child to a different city or country without the consent of the other guardian. Moving a child from Auckland to Christchurch, for example, significantly impacts the relationship between the child and the other parent. This is considered a guardianship decision. If you wish to relocate and the other guardian disagrees, you must apply to the Family Court for a direction.
2. Medical Treatment
While routine GP visits are day-to-day matters, significant medical procedures require consent. This includes elective surgeries, vaccinations, orthodontic work, or psychological counseling. In cases where guardians disagree on medical treatment (for example, regarding immunizations), the court may need to intervene to decide what is in the best interests of the child.
3. Education
Choosing a school is a major guardianship decision. You cannot unilaterally enroll a child in a new school or switch them from public to private education without consultation. This also applies to decisions about homeschooling or boarding school.
4. Religion and Culture
Guardians have the right to determine the child’s religious upbringing. One parent cannot unilaterally change the child’s religion or prohibit the child from participating in the religious practices they were raised in, provided those practices are not harmful.
5. Changes of Name
Changing a child’s surname or first name officially requires the consent of all guardians. This is strictly enforced by the Department of Internal Affairs.
Appointing Testamentary and Court-Appointed Guardians
Guardianship is not limited to biological parents. There are legal mechanisms to appoint additional guardians, which is a crucial consideration for estate planning and blended families.
Testamentary Guardians
A testamentary guardian is someone appointed via a parent’s Will. If a parent dies, the person they named in their Will becomes a legal guardian of the child. It is important to understand that a testamentary guardian does not automatically get day-to-day care (custody). They get the right to be involved in the major decisions. However, they can apply for day-to-day care if they believe it is in the child’s best interest.
Court-Appointed Guardians
The Family Court can appoint a guardian for a specific purpose or generally. This often happens in extended family situations where a grandparent or aunt/uncle is caring for a child long-term. They may apply to be appointed as an additional guardian to ensure they have the legal authority to sign medical forms and enroll the child in school.

Removing a Legal Guardian: Is It Possible?
A common question from frustrated parents is: “Can I remove my ex as a guardian?” The short answer is: It is extremely difficult.
In New Zealand, the Family Court views the relationship between a child and their natural guardians as paramount. A parent will not be removed as a guardian simply because they are a “deadbeat,” do not pay child support, or rarely visit the child. These are issues of day-to-day care and contact, not guardianship.
To remove a guardian, the Court must be satisfied that the person is unwilling or unable to perform their duties, or that their removal is necessary for the child’s welfare. This is a very high threshold. Usually, removal is reserved for cases of severe abuse, gross negligence, or where a parent has been absent for many years and their continued guardianship is actively obstructing the child’s life (e.g., refusing to sign passport applications essentially barring the child from travel).
Resolving Disputes Between Guardians
When guardians cannot agree on a major decision—such as which high school the child should attend—the law requires them to attempt to resolve the dispute before entering the courtroom.

Family Dispute Resolution (FDR)
Before applying to the Family Court, guardians are generally required to attend Family Dispute Resolution (FDR). This is a mediation service designed to help parents reach a consensus. If an agreement is reached, it can be written up and potentially made into a court order.
Court Directions
If FDR fails, a guardian can apply to the Family Court for a “Order to Settle a Dispute between Guardians.” The judge will hear both sides and make a decision based on the paramount principle: the welfare and best interests of the child. The judge does not necessarily choose one parent’s side over the other but may make an independent decision or appoint a lawyer for the child to ascertain the child’s views.
Understanding the distinction between legal guardianship NZ and day-to-day care is vital for successful co-parenting. While day-to-day care manages the present moment, guardianship protects the future. Respecting these boundaries ensures that children are shielded from adult conflict and provided with the stability they need to thrive.
People Also Ask
What is the difference between custody and guardianship in NZ?
In New Zealand law, ‘custody’ is now called ‘day-to-day care’ and refers to the daily living arrangements and routine care of the child. ‘Guardianship’ refers to the legal right to make major, long-term decisions about the child’s upbringing, such as education, religion, and medical care. You can be a guardian without having day-to-day care.
Can a mother stop a father from seeing his child in NZ?
Generally, no. Unless there is a court order preventing contact or a genuine, immediate risk to the child’s safety, both parents usually have a right to maintain a relationship with their child. Denying contact without valid legal justification can be viewed negatively by the Family Court.
Does a father automatically get guardianship in NZ?
A father is automatically a guardian if he is married to or in a civil union with the mother at any time during the pregnancy, or if his name appears on the child’s birth certificate (for children born on or after 1 July 2005). Otherwise, he may need to apply to the court to be appointed as a guardian.
At what age can a child decide who they live with in NZ?
There is no specific age where a child can unilaterally decide. However, the Care of Children Act requires that a child’s views be taken into account, with the weight given to those views increasing as the child gets older and more mature. By age 12-14, their preferences are usually given significant weight by the Court.
Can a legal guardian take a child overseas without permission NZ?
No. Taking a child overseas is a guardianship decision. You must have the consent of all other guardians or a court order allowing the travel. Taking a child out of New Zealand without this consent can be considered international child abduction.
What rights does a step-parent have in NZ?
Step-parents do not automatically have guardianship or day-to-day care rights. However, they can apply to the court to be appointed as an additional guardian or to have day-to-day care or contact, especially if they have played a significant role in the child’s life.
