Separation Asset Split Calculator NZ
This calculator gives you an indicative starting point for how relationship property might be split between two partners on separation in New Zealand, based on the general principle that relationship property is shared equally. You enter the value of the shared assets, the family home, shared savings and investments, and vehicles and other chattels, then enter any shared debts still owing, such as the mortgage or loans. The calculator adds up the total assets, subtracts the debts to work out the net relationship property, and shows the amount each partner would receive on a straight 50/50 split. It is designed to help you understand the broad shape of a split while you work through separating your finances, whether you are budgeting for what comes next or preparing for a conversation with a lawyer. Real-life outcomes are rarely this simple. What counts as relationship property rather than separate property, such as some inheritances, gifts or assets owned before the relationship began, can change the numbers significantly, and short relationships and other circumstances add further exceptions under New Zealand law. Because of this complexity, treat the result here as an indicative estimate only, not a legal determination of entitlement, and get independent legal advice before making any decisions about dividing your relationship property.
As a general principle, relationship property is shared equally, but there are important exceptions for separate property, short relationships and other factors. This is an indicative starting point only. Relationship property is complex, so get legal advice for your situation.
How it works
The calculator adds the shared assets, the family home, savings, investments and chattels, then subtracts the shared debts to find the net relationship property. It divides that equally to show each partner share, reflecting the general equal-sharing principle for relationship property. Real outcomes depend on what counts as relationship versus separate property and other factors, so this is a starting point, not a determination.
Worked example
A family home of $800,000, $80,000 of savings and $50,000 of chattels is $930,000 of assets. Less $300,000 of shared debt, the net relationship property is $630,000, so an equal split is about $315,000 each, before considering any separate property or exceptions.
