New Zealand's Property (Relationships) Act outlines how assets are divided when a relationship ends. It applies to married, civil union, and de facto couples, usually after three years.

The default is a 50/50 split of relationship property, which includes the family home, shared assets, and KiwiSaver funds accrued during the relationship. To create different terms, couples can establish a contracting out agreement ("prenup"), which requires independent legal advice for both parties to be valid.
