Apply for Guardianship NZ: Who Can Apply and How

Guardianship in New Zealand is the legal right to make major decisions about a child's upbringing — education, medical treatment, religious practices, name changes, and international travel. Most biological parents are automatic guardians, but there are situations where guardianship needs to be applied for: unmarried fathers not on the birth certificate, step-parents, grandparents raising grandchildren, or whānau members taking on a parenting role.

Who Is an Automatic Guardian?

Under the Care of Children Act 2004, you're automatically a guardian if:

• You're the child's mother — guardianship is automatic from birth
• You're the child's father and you were married to or in a civil union with the mother at any point between conception and birth
• You're the child's father and you were living with the mother at any point between conception and birth (de facto relationship)
• You're the child's father and your name is on the birth certificate

If none of these apply — for example, if you're an unmarried father not named on the birth certificate and you never lived with the mother — you are not an automatic guardian and need to apply to the Family Court.

Who Can Apply for Guardianship?

Section 19 of the Care of Children Act 2004 specifically allows the following person to apply to be appointed as a guardian:

• A father who was not the mother's spouse, civil union partner, or de facto partner

Other people seeking appointment use the court-appointed guardianship provisions, including Section 27 where applicable:

• A parent's spouse or partner
• A grandparent, whānau member, or other caregiver
• Oranga Tamariki in care and protection proceedings

Under Section 27, the court may appoint a person as guardian on an application by any person. It may also do so on its own initiative when making an order removing a guardian under Section 29.

What Guardianship Includes

Guardians have the right to be consulted on — and must agree to — major decisions including:

• Which school the child attends
• Non-routine medical treatment (surgery, specialist referrals, psychiatric treatment)
• Religious upbringing and practices
• Changes to the child's name
• International travel
• Living arrangements and significant lifestyle changes

Guardianship is separate from day-to-day care. You can be a guardian without having the child live with you. Conversely, having day-to-day care doesn't automatically make you a guardian (though courts often appoint guardianship alongside care orders).

The Application Process

Step 1: File an application at your local Family Court registry. You'll need:

• Application form
• A supporting affidavit explaining your relationship with the child, the reasons you're seeking guardianship, and how the appointment would serve the child's best interests
• Filing fee: There is no court filing fee for a guardianship application

Step 2: Serve the application. Provide exact copies and ensure the application is served on all existing guardians and any other person the court requires to be notified. Existing guardians have the right to file a response — they can support, oppose, or take no position on your application.

Step 3: Court assessment. The judge applies the best-interests test under Section 4. They consider your relationship with the child, your capacity to exercise guardianship responsibilities, the views of existing guardians, and the child's own views (weighted by age and maturity).

Step 4: Decision. If the application is unopposed and clearly in the child's interests, the judge may make the order on the papers (without a hearing). If it's contested, a hearing is scheduled.

Guardianship for Step-Parents

Step-parent guardianship applications are increasingly common in New Zealand. If you've been parenting a child alongside your partner and want formal decision-making rights — the ability to consent to medical treatment, enrol the child in school, or authorise travel — you need a guardianship appointment.

The court considers:

• The length and quality of your relationship with the child
• Whether the child views you as a parent figure
• The existing guardians' positions (particularly the non-resident biological parent)
• Whether adding another guardian would create conflict in decision-making

A step-parent guardianship doesn't replace the biological parent's guardianship — it adds to it. The child can have three or more guardians, all of whom must be consulted on major decisions.

Removing Guardianship

Guardianship can be removed under Section 29 of the Care of Children Act 2004 only when removal is in the child's best interests — for example, where a guardian is seriously unfit or unwilling to perform guardianship duties in a way that harms the child. The bar is deliberately high because guardianship protects the child's connection to their parents.

Next Steps

Whether you're an unmarried father seeking recognition, a grandparent formalising an existing care arrangement, or a step-parent who wants the legal authority to make decisions for a child you've been raising, the application process requires demonstrating that guardianship serves the child's best interests.
