How we handle money in relationships is one of the most significant — and least discussed — factors in financial wellbeing. In New Zealand, the legal framework around relationship property affects millions of couples, yet many don’t understand how it works until they separate.
This section covers money and relationships from every angle: combining finances as a couple, the legal framework of the Property Relationships Act, teaching children about money, and recognising financial abuse.

Why Money and Relationships Are Inseparable
Money is one of the most common sources of conflict in relationships — and one of the most common factors in relationship breakdown. Research consistently shows that financial incompatibility (different spending habits, different attitudes to risk, different goals) causes more relationship problems than actual financial hardship.
In New Zealand specifically, the Property Relationships Act 1976 means that financial decisions you make in a relationship — whether to buy a home together, whose name is on the mortgage, whether to commingle an inheritance — can have legally binding consequences you may not have anticipated.
Key NZ Legal Context
- The Property Relationships Act applies to all married couples and de facto couples of 3+ years — relationship property is split 50/50 on separation by default
- A contracting-out agreement (pre-nup) can change these defaults — but must be in writing with independent legal advice for each party
- KiwiSaver is relationship property for contributions made during the relationship
- Financial abuse is recognised as a form of domestic violence under the Family Violence Act 2018
