Day-to-Day Care NZ: What It Means and How It's Decided

If you've been told your children will be in someone's "day-to-day care," you're dealing with one of three legal concepts that replaced the old custody system in New Zealand. Understanding exactly what day-to-day care covers — and what it doesn't — determines your parenting schedule, your child support obligations, and your decision-making rights.

Day-to-Day Care vs Guardianship vs Contact

Under the Care of Children Act 2004, New Zealand replaced "custody" and "visitation" with three separate concepts:

Day-to-day care is the operational side of parenting. The parent with day-to-day care handles the child's daily residence, meals, school runs, bedtime routines, and immediate supervision. If your child lives primarily with you Monday to Friday, you have primary day-to-day care during that period.

Guardianship is the decision-making layer. Both parents are typically guardians regardless of the care arrangement. Guardianship covers major decisions: schooling, non-routine medical treatment, religious upbringing, name changes, and international travel. These decisions require both guardians to agree.

Contact is the time a child spends with the parent who doesn't have care at that moment. Contact includes overnight stays, weekend time, holiday blocks, and phone or video calls.

The critical distinction: the parent with day-to-day care makes routine daily decisions (what the child eats, when they go to bed, what they wear to school). But that parent cannot unilaterally decide to change schools, move cities, or get the child a non-routine medical procedure — those require the other guardian's agreement or a court order.

How Day-to-Day Care Affects Child Support

This is where the overnight count becomes financially significant. Inland Revenue calculates child support using care-percentage thresholds based on the number of nights your child stays with you per year:

• 0–102 nights (under 28%) — your care is classified as "nil care" and you receive zero credit in the child support formula
• 103–127 nights (28–34%) — you hit the first threshold and receive a 24% care cost credit, significantly reducing your child support liability
• 128+ nights (35%+) — you become eligible to receive child support if your income is lower than the other parent's
• 172–193 nights (48–52%) — care is deemed equal

A single night's difference — 102 vs 103 — can shift your annual child support by thousands of dollars. This makes precise scheduling essential, not just for your parenting relationship but for your financial planning.

Shared Day-to-Day Care

New Zealand law doesn't presume that children should live primarily with one parent. The court can — and frequently does — order shared day-to-day care, where the child splits time roughly equally between both households.

Common shared-care schedules include:

• 2-2-3 rotation — two days with one parent, two with the other, then a three-day weekend, alternating. Works well for younger children who need frequent contact with both parents.
• 2-2-5-5 rotation — specific weekdays always with the same parent (e.g., Monday–Tuesday with Mum, Wednesday–Thursday with Dad), then alternating five-day blocks including the weekend. Gives weekly consistency for school routines.
• Alternating weeks — a full seven days with each parent. Better suited for older children and teenagers who can handle longer stretches away from each parent.

The right schedule depends on the child's age, the distance between households, both parents' work patterns, and the child's school and social commitments. A schedule that works for a five-year-old will likely need revising when that child starts secondary school.

How the Family Court Decides Day-to-Day Care

If parents can't agree, the Family Court applies the best-interests test under Section 4 of the Care of Children Act 2004. The judge considers:

• Safety from violence, abuse, or neglect
• Continuity of the child's existing care arrangements, schooling, and friendships
• The quality of the child's relationship with each parent
• Each parent's capacity to support the child's relationship with the other parent
• The child's cultural identity and connections to whānau, hapū, and iwi
• The child's own views, weighted by age and maturity

There's no gender presumption. Section 4(3) explicitly states that neither parent has an advantage based on sex. The decision is entirely about what works best for this specific child.

Changing an Existing Day-to-Day Care Arrangement

If circumstances change — a parent relocates, a child's needs evolve, or the current arrangement isn't working — either parent can apply to vary the existing parenting order. You'll need to show a material change in circumstances and go through FDR mediation again (unless an exemption applies).

Next Steps

Getting day-to-day care right means building a schedule that serves your child's developmental needs and aligns with the IRD care thresholds that drive your financial obligations.

The New Zealand Child Custody & Parenting Plan Guide provides age-appropriate schedule templates, an overnight-count calculator mapped to IRD care cliffs, and worksheets for documenting the care arrangement in a format the Family Court expects.
