Spousal maintenance and child support in NZ are distinct financial provisions governed by New Zealand family law, designed to ensure financial fairness and the well-being of dependents after separation. Spousal maintenance provides financial support to a former partner, while child support covers the costs of raising children, with calculations primarily managed by the Inland Revenue Department (IRD).
Understanding Spousal Maintenance in New Zealand
In New Zealand, spousal maintenance, often referred to as partner maintenance, is a payment made by one spouse or partner to the other after separation, intended to help the financially weaker party meet their reasonable needs. Unlike child support, which is primarily formula-based, spousal maintenance is discretionary and determined by the courts based on individual circumstances. It acknowledges that one partner may have sacrificed their career or earning potential during the relationship to care for children or support the other partner’s career, leading to a financial disparity upon separation. The law seeks to ensure a fair transition, preventing undue hardship.
Eligibility Criteria for Spousal Maintenance
To be eligible for spousal maintenance in New Zealand, a spouse or partner must demonstrate that they cannot reasonably meet their own reasonable needs because of the effects of the relationship. The Family Court considers several key factors when assessing eligibility. These include the disparity in earning capacity that arose from the relationship, the division of roles during the relationship (e.g., one partner being the primary caregiver), and the financial resources of both parties. It’s not about equalizing incomes but rather ensuring the claimant can maintain a reasonable standard of living. The application must be made within a specified timeframe following the end of the relationship, typically within two years of a divorce or three years of the dissolution of a de facto relationship.
Factors Influencing Spousal Maintenance Orders
When determining the amount and duration of spousal maintenance, the court takes a holistic view, considering factors such as:
- The income and earning capacity of each party: This includes current earnings, potential future earnings, and any limitations due to age, health, or childcare responsibilities.
- The financial needs and obligations of each party: This covers living expenses, debts, and responsibilities towards new dependents.
- The standard of living during the relationship: While not a guarantee, the court may consider the lifestyle enjoyed by the couple.
- The duration of the relationship: Longer relationships often result in greater interdependence and thus a stronger claim for maintenance.
- The extent to which one partner’s earning capacity has been impaired: For instance, a parent who put their career on hold to raise children.
- The responsibilities of each party for the care of children: Childcare responsibilities can significantly impact earning capacity and needs.
The court aims to facilitate self-sufficiency for the receiving partner within a reasonable timeframe, meaning maintenance orders are often for a finite period rather than indefinite. The focus is on enabling a transition rather than permanent dependence.
Types and Duration of Spousal Maintenance
Spousal maintenance can be ordered in various forms:
- Lump-sum payments: A single, one-off payment.
- Periodical payments: Regular payments (e.g., weekly, fortnightly, monthly) for a specified period or until a trigger event occurs (e.g., remarriage, gainful employment).
- Interim maintenance: Temporary payments ordered quickly to provide immediate relief while the full application is being heard.
The duration of maintenance is generally limited to what is necessary to allow the recipient to become financially independent. This might involve supporting them through retraining, further education, or a job search. It’s rare for maintenance to be ordered indefinitely, especially in shorter relationships or where the recipient has a strong capacity for self-sufficiency. The courts regularly review these orders, and they can be varied or discharged if there’s a significant change in circumstances for either party.

Decoding Child Support Calculations by IRD
Child support in New Zealand is a financial contribution made by parents to assist with the costs of raising their children when they no longer live together. Unlike spousal maintenance, child support is primarily administered and calculated by the Inland Revenue Department (IRD) using a specific legislative formula. This system aims to provide a consistent and fair approach to determining financial contributions, ensuring children’s well-being is prioritized. The Child Support Act 1991 governs these payments, establishing clear guidelines for assessment and collection. The IRD plays a crucial role in assessing, collecting, and distributing child support payments, simplifying the process for many families.
The IRD Child Support Formula: A Step-by-Step Guide
The IRD’s child support formula is a multi-step calculation designed to determine each parent’s share of the costs of raising their child(ren). The core principles involve assessing the income of both parents, accounting for the care arrangements, and deducting a living allowance. Here’s a simplified breakdown:
- Calculate each parent’s “child support income”: This is generally taxable income minus a living allowance and any primary care costs for other children.
- Determine the “cost of living allowance” for each parent: A standard allowance is deducted from income to ensure parents can meet their own basic needs.
- Ascertain the “child support percentage”: This is based on each parent’s share of the total combined child support income.
- Factor in “care arrangements”: The percentage of care each parent provides (e.g., 50/50, 60/40) directly influences their net payment or receipt. The more care a parent provides, the less they might pay, or the more they might receive.
- Calculate the “child support amount”: The formula then applies the child support percentages and care arrangements to a total “child support cost” figure, which is a standardized cost based on the number and age of the children.
The IRD provides detailed calculators on their website, allowing parents to estimate their obligations. It is important to keep IRD updated with any changes in income or care arrangements to ensure accurate assessments. More information can be found on the Inland Revenue Department’s Child Support page.
Income Assessment and Living Allowances
A crucial component of the IRD child support formula is the accurate assessment of each parent’s income. IRD primarily uses taxable income from the previous tax year, which includes salary, wages, self-employment income, and most social welfare benefits. However, IRD has provisions to use an estimate of current income if a parent’s financial situation has significantly changed (e.g., job loss, new employment). It’s vital to apply for an estimate if your income has changed by at least 15% from the previous tax year to avoid over- or underpayment. From this assessed income, a living allowance is deducted for each parent. This allowance is a standard amount set by law, intended to ensure that parents retain sufficient funds to meet their basic living expenses before contributing to child support. The living allowance helps to balance the financial responsibilities towards children with a parent’s own capacity to provide for themselves.
Care Arrangements and Their Impact
The amount of time each parent spends caring for the child(ren) is a significant factor in the child support calculation. The IRD uses specific care percentage thresholds:
- Less than 29% care: Considered a non-caring parent, full child support liability.
- 29% to 52% care: Parents share care, and child support liability is adjusted accordingly.
- 52% to 73% care: Parents share care, and child support liability is adjusted.
- 73% or more care: Considered the primary caregiver, potential recipient of child support.
Accurate recording and reporting of care arrangements to IRD are paramount. If care arrangements change, it’s essential to notify IRD promptly to ensure the child support assessment remains correct. Discrepancies in reported care can lead to disputes and incorrect payments, highlighting the importance of clear communication and documentation between parents and with IRD.

Navigating Variations and Exceptions to Standard Support
While the IRD child support formula provides a standardized approach, family situations are often complex and may not fit neatly into the standard calculations. Both the Child Support Act and the Family Court provide mechanisms for varying the standard assessment where unique circumstances warrant it. These variations ensure that the support paid or received genuinely reflects the child’s needs and the parents’ capacities, moving beyond the strict formula when necessary. It’s an important safeguard to prevent undue hardship or to address specific financial requirements that the basic formula cannot capture. Understanding these avenues for variation is crucial for parents who believe their situation is exceptional.
Applying for an Administrative Review
If a parent believes the IRD’s standard child support assessment does not fairly reflect their circumstances or the children’s needs, they can apply for an administrative review. This is an internal IRD process where a Review Officer will reconsider the assessment based on specific “grounds for departure” from the formula. These grounds can include:
- High costs of contact (e.g., travel expenses for visitation).
- Special needs of the child (e.g., medical, educational).
- High costs of supporting another child.
- Unusual expenses for the child.
- A parent’s unusually high or low income compared to their earning capacity.
- Payment of school fees for the child.
The Review Officer will consider evidence from both parents before making a decision. This process is designed to be less formal and costly than court proceedings, offering an accessible route for adjustments. If a parent disagrees with the review decision, they may then apply to the Family Court for a departure order.
Court-Ordered Departure from the Formula
Where an administrative review does not resolve the issue, or if the circumstances are highly complex, a parent can apply to the Family Court for a “departure order.” The court has broader discretion than an IRD Review Officer and can make orders that deviate significantly from the standard formula. The grounds for a court-ordered departure are similar to those for an administrative review but allow for a more in-depth examination of the financial realities and the specific needs of the family. The court will consider all relevant factors, ensuring any departure from the formula is in the best interests of the child. This process typically involves legal representation and presenting a detailed case to the judge.
Private Agreements for Spousal and Child Support
Parents also have the option to enter into private agreements for both spousal maintenance and child support.
- Child Support: Parents can make a “private agreement” or a “child support agreement” through IRD. A private agreement allows parents to set their own terms outside of IRD’s involvement, but it is not enforceable by IRD. A child support agreement, however, can be registered with IRD and then enforced by them. These agreements must meet certain criteria and be in the children’s best interests.
- Spousal Maintenance: For spousal maintenance, separated partners can enter into “relationship property agreements” (also known as “contracting out agreements” or “separation agreements”) which can include provisions for spousal maintenance. These agreements are legally binding if properly drawn up and witnessed by independent lawyers, ensuring both parties receive legal advice. This offers flexibility and often avoids the stress and cost of court proceedings, but careful legal drafting is essential.
It is highly advisable to seek independent legal advice before entering into any private agreement to ensure it is fair, enforceable, and fully understood by both parties.

Enforcement of Spousal Maintenance and Child Support Payments
Ensuring that ordered or agreed-upon support payments are actually made is a critical aspect of family law. When payments are missed, it can cause significant financial distress for the receiving parent and, by extension, for the children. Both the IRD and the Family Court have powers to enforce child support and spousal maintenance obligations. Understanding these enforcement mechanisms is crucial for recipients who are not receiving their due payments and for payers who may face consequences for non-compliance. Prompt action is often necessary to recover arrears and re-establish regular payments. New Zealand has robust systems in place to address non-payment, aiming to uphold financial responsibility.
IRD’s Role in Child Support Enforcement
For child support assessments administered by IRD, the department has extensive powers to enforce payment. If a liable parent falls into arrears, IRD will initially send reminders and attempt to make contact. If payments remain outstanding, IRD can take various enforcement actions, including:
- Deductions from wages or salaries: IRD can issue a Deduction Notice to an employer, requiring them to deduct child support directly from the payer’s earnings.
- Deductions from bank accounts: Money can be directly taken from bank accounts.
- Deductions from social welfare benefits: If the liable parent receives a benefit, child support can be deducted from it.
- Withholding tax refunds: Any tax refunds due to the liable parent can be intercepted and applied to arrears.
- Placing charges on property: A charge can be placed on real estate or other assets.
- Preventing international travel: In serious cases of non-payment, a liable parent can be prevented from leaving New Zealand.
IRD’s enforcement powers are comprehensive and designed to ensure that children receive the financial support they are entitled to. It is important for parents experiencing non-payment to contact IRD immediately.
Legal Avenues for Spousal Maintenance Enforcement
Unlike child support, spousal maintenance orders or agreements are primarily enforced through the Family Court. If a former partner fails to make spousal maintenance payments, the recipient can apply to the Family Court for enforcement. The court has several tools at its disposal, including:
- Attachment orders: Similar to IRD deductions, the court can order an employer to deduct maintenance directly from wages.
- Distress warrants: Authorising the seizure and sale of property to cover arrears.
- Charging orders: Placing a charge over the payer’s property.
- Warrant to arrest: In extreme cases of willful non-compliance, a warrant for arrest can be issued.
Enforcement of spousal maintenance often requires legal advice and formal court applications. Keeping accurate records of payments made and missed is crucial for any enforcement action. Legal representation is highly recommended to navigate these complex processes effectively, and further information can be found on the New Zealand Ministry of Justice website.
Consequences of Non-Payment
The consequences of failing to meet spousal maintenance or child support obligations can be severe. For child support, IRD can impose penalties and interest on overdue amounts, which can significantly increase the total debt. As mentioned, international travel bans and interception of tax refunds are also possible. For both types of support, non-compliance can damage credit ratings and lead to significant legal costs. More importantly, it can cause immense stress and financial hardship for the receiving parent and the children, undermining their stability and well-being. The Family Court takes non-compliance seriously, viewing it as a disregard for court orders or statutory obligations, and will apply the full force of the law to ensure payments are made. It is always better for a payer experiencing financial difficulty to communicate with IRD or the receiving party and seek a variation rather than simply ceasing payments.
Seeking Expert Guidance for Your Family Law Matters
Navigating the complexities of spousal maintenance and child support calculations in New Zealand can be daunting. The legal framework, the IRD’s specific formulas, and the discretionary nature of court decisions require a clear understanding of your rights and obligations. Whether you are seeking support, liable to pay, or looking to vary an existing order, obtaining expert legal advice is invaluable. A qualified family lawyer can provide tailored guidance, help you understand the nuances of your specific situation, assist with applications, negotiate agreements, and represent you in court if necessary. Their expertise ensures that your best interests and, most importantly, the best interests of your children, are protected throughout the process. Don’t hesitate to seek professional assistance to ensure fair and equitable outcomes during a challenging time.
People Also Ask
How is spousal maintenance different from child support in New Zealand?
Spousal maintenance is financial support for a former partner to help them meet their reasonable needs post-separation, typically determined by the Family Court based on discretion and individual circumstances. Child support is a financial contribution for the care of children, primarily calculated by the IRD using a specific formula based on parental incomes and care arrangements, focusing on the child’s costs.
Can spousal maintenance be varied or stopped in NZ?
Yes, spousal maintenance orders can be varied or stopped by the Family Court if there is a significant change in circumstances for either party, such as a change in income, employment status, or the recipient’s ability to become self-sufficient. Orders are often for a finite period with the goal of enabling financial independence.
What if my income changes after a child support assessment by IRD?
If your income changes by 15% or more from what was used in your last child support assessment, you should contact IRD immediately to apply for an “estimate of income.” This ensures your child support obligations are based on your current financial situation, preventing potential overpayment or underpayment.
What are the consequences of not paying child support in New Zealand?
Non-payment of child support can lead to significant consequences, including penalties and interest on arrears, deductions from wages or bank accounts, interception of tax refunds, placing charges on property, and in serious cases, a ban on international travel. IRD has strong enforcement powers to recover overdue payments.
Can I make a private agreement for child support instead of using IRD?
Yes, parents can enter into a private agreement for child support. If registered with IRD, it becomes a “child support agreement” and can be enforced by IRD. Without IRD registration, it is a non-enforceable private agreement. It is highly recommended to seek legal advice to ensure any private agreement is fair and legally sound.
How long can I receive spousal maintenance in NZ?
The duration of spousal maintenance in NZ is determined by the Family Court and is generally limited to the period necessary for the recipient to become financially independent. It is rare for maintenance to be ordered indefinitely; the focus is on facilitating a transition to self-sufficiency, which might involve support for retraining or seeking employment.
