Property Division for Civil Unions in New Zealand

Civil Union Partners Have the Same Property Rights as Married Couples

The Property (Relationships) Act 1976 applies identically to marriages and civil unions for property matters. When the Civil Union Act 2004 came into effect, the PRA was amended to extend relationship-property rights — the 50/50 equal-sharing default, the classification of relationship versus separate property, and KiwiSaver division — to civil union partners. Spousal maintenance is governed by the Family Proceedings Act 1980.

There is no lesser tier of property rights for civil unions. The rules governing the family home, family chattels, debts, separate property, intermingling, and contracting-out agreements work in exactly the same way.

The Three-Year Threshold Still Applies

For a civil union lasting three years or more, the PRA's equal-sharing presumption applies in full as the default. Relationship property — the family home, savings accumulated during the union, KiwiSaver contributions during the relationship, vehicles, household contents — is generally divided equally, subject to statutory exceptions.

For civil unions shorter than three years, the court departs from equal sharing and divides property based on each partner's contributions. The family home and family chattels are still shared equally unless extraordinary circumstances make that unjust. The substantial-contribution and serious-injustice test described for short-duration de facto relationships is different; those rules generally apply only where a child is involved or a partner has made substantial contributions and failure to divide would cause serious injustice. They do not govern civil unions.

Dissolution of a Civil Union

Ending a civil union follows the same process as ending a marriage. The Family Proceedings Act 1980 requires a continuous two-year separation period before an application for dissolution can be filed. The same trial reconciliation allowance applies — periods of resumed cohabitation totalling up to three months do not reset the two-year clock.

Since October 2025, the family violence exception also applies to civil unions. A partner who holds a final protection order against their civil union partner can apply for immediate dissolution without waiting two years.

Property division does not require waiting for the dissolution. Partners can negotiate and execute a Section 21A agreement at any time after separation, settling the financial split independently of the dissolution timeline.

Practical Differences Are Minimal

The only material difference between a civil union and a marriage in the context of property division is administrative: the dissolution application form references the civil union certificate rather than the marriage certificate, and the Family Court order is styled as a dissolution of civil union.

For property division purposes, the legal framework, the court's powers, the classification rules, and the settlement options are identical. Every worksheet, checklist, and process step that applies to a married couple's property split applies equally to civil union partners.

The NZ Financial Split Navigator covers the full PRA framework that applies to both marriages and civil unions — including asset inventories, KiwiSaver calculations, and settlement preparation templates.
