Buying a First Home With Family in NZ (2026): KiwiSaver, Co-Ownership and Who Owns What

Several people buying a first home together can each make their own KiwiSaver withdrawal if they each meet the 3-year rule. Here is how co-ownership, tenants in common and a sharing agreement decide who owns what.

Buying a first home with a parent, a sibling or a friend is more common in New Zealand than it used to be. Pooling deposits and incomes can get a group into a home that none of them could buy alone. But sharing a home raises questions a couple buying together rarely faces: can each person use their KiwiSaver, whose name goes on the title, who owns what share, and what happens if one person wants out. This guide to buying a first home with family using KiwiSaver in NZ works through each of those.

TL;DR: Several people buying a first home together can each make their own KiwiSaver first-home withdrawal, provided each has been a member for at least 3 years and each leaves $1,000 behind. Most family and friend groups hold the property as tenants in common, which records each person's share, and a written property-sharing agreement sets out the rules before anyone signs. ¹²⁸

Can each person use their KiwiSaver when buying a home together?

In most cases, yes. The KiwiSaver first-home withdrawal is assessed per member, not per household or per property. Each eligible co-buyer applies individually through their own KiwiSaver provider, so a group of two or three people buying together can each make their own withdrawal if they each meet the rules. ¹

To withdraw, each person must meet the same core conditions that apply to any first-home buyer:

• They have belonged to KiwiSaver (or a complying superannuation fund) for at least 3 years, counted from their first contribution. ¹
• They leave a minimum of $1,000 in their own account after the withdrawal. ²
• The home is in New Zealand, they intend to live in it as their principal place of residence, and it is not an investment property. ³
• They have not made a KiwiSaver first-home withdrawal before. ³

That $1,000 floor applies to each person separately. So a group of three each leaves $1,000, which is $3,000 held back across the three accounts in total, not $1,000 between them. It is worth confirming each person's withdrawable figure before you set a deposit expectation. ²

One more point that catches people out: funds transferred into KiwiSaver from an Australian complying superannuation scheme cannot be withdrawn for a first home. If any co-buyer lived and worked in Australia and brought their super across, ask their provider to split out the NZ-sourced amount before counting it toward the deposit. ²

Because each withdrawal is assessed individually, a group does not all have to qualify at once. If one person is short of three years, the others can still withdraw — though it changes the deposit maths and, often, who can realistically be on the title. Our guide to buying a first home with a partner using KiwiSaver walks through the same per-person logic for couples.

Buying with parents, a sibling or a friend: what's different from a couple?

A couple usually shares one set of finances and plans to keep the home together long term. A parent, sibling or friend group often does not. That difference drives most of what follows, so it is worth naming the practical contrasts up front.

• Different contributions. People rarely put in equal deposits. One person might fund 60% and another 40%, which the ownership structure needs to record fairly.
• Different time horizons. A friend buying with you may want to sell in five years; a parent may be helping for the long term. A couple usually plans together.
• No automatic legal relationship. Property (Relationships) Act rules that govern how a couple splits a home do not apply to friends or to a parent and adult child in the same way. Without a written agreement, sorting out a dispute can be slow and expensive.
• Separate lives and risks. Each owner has their own income, their own debts and their own future. One person's job loss, illness or relationship breakdown can affect everyone on the mortgage.

None of this means co-buying is a poor idea. For many people it is the realistic path into a first home, and first-home buyer activity has been at record levels — December 2025 recorded 3,597 new mortgages to first-home buyers, the highest monthly figure on record. ⁹ It does mean the structure and the paperwork matter more than they do for a couple. The rest of this guide is about getting those right.

What if one co-owner has owned a home before?

A previous home owner is not automatically locked out. There is a "second-chance" (previous home owner) pathway that can let them use their KiwiSaver, but it works differently from the standard withdrawal, and Kāinga Ora — not just the provider — has to approve them first. ⁴

The steps are:

1. The person applies to Kāinga Ora, which decides whether they are in the same financial position as a first-home buyer.

2. If approved, Kāinga Ora issues a letter to forward to their KiwiSaver provider.

3. The provider then processes the withdrawal.

To qualify, the applicant must not currently own any interest in property (Māori land aside) and must have realisable assets below 20% of the area's house-price cap for an existing or older property. ⁴ "Realisable assets" means things they could reasonably sell to fund a deposit — cash, shares, a second vehicle, a holiday home — not everyday household goods. Because this pathway needs a Kāinga Ora determination before the provider can act, it takes more lead time than a standard withdrawal, so start it early. Our guide on the previous home owner second-chance withdrawal covers the asset test in more detail.

It is worth being clear about what closed and what did not. The First Home Grant (the cash top-up of up to $5,000 for an existing home or up to $10,000 for a new build) was discontinued and stopped accepting applications from 22 May 2024. It is no longer available to anyone, including groups buying together. ⁵ The Kāinga Ora First Home Loan is still available and lets eligible buyers purchase with as little as a 5% deposit instead of the usual 20%. ⁶ For a group, the income caps are the figure to check: $95,000 or less for an individual buyer without dependants, $150,000 or less for an individual with one or more dependants, and $150,000 or less combined for two or more buyers. ⁶ A combined cap for a group is easy to exceed, so confirm it before relying on the scheme.

Joint tenants vs tenants in common: who owns what?

This is the decision that determines who owns what, and what happens to a share when an owner dies. New Zealand property is usually held one of two ways. ⁷⁸

Sources: govt.nz — Buying your first home, as at 8 December 2025. ⁷⁸

Joint tenants own the property together as a single undivided interest with the right of survivorship: when one owner dies, their interest passes automatically to the surviving joint tenant(s) rather than under their will. This is the structure couples commonly use, because each partner generally wants the other to inherit the home outright. ⁷

Tenants in common each hold a distinct share, which can be equal or unequal. Each owner's share can be passed on by their will. ⁸ For a parent, sibling or friend group, this is usually the more suitable structure, for two reasons: it records who contributed what (so a 60/40 deposit can be a 60/40 ownership split), and it lets each person leave their share to whoever they choose rather than automatically to the other owners. People buying with family who contribute different amounts and want their share protected commonly choose this structure. ⁸

Which structure fits depends on the relationships, the contributions and what each person wants to happen to their share over time. This is a legal decision as much as a financial one. Smiths Financial does not provide legal advice. This is general information only — please consult a property lawyer before you decide how to hold the title.

How a property-sharing agreement protects each owner

A property-sharing agreement (sometimes called a co-ownership or property-sharing deed) is a written contract between the owners, drawn up by a lawyer, that sets the rules before anyone signs. It sits as a layer over the ownership structure: the title records who owns what, and the agreement records how the owners will run the arrangement and what happens when things change. For a friend or family group, it is the single most useful document to get right.

A well-drafted agreement commonly covers:

• Each person's ownership share and how it lines up with their deposit and ongoing contributions.
• Who pays what — the mortgage, rates, insurance, maintenance and how any shortfall is handled.
• What happens if someone wants to sell their share — whether the others get first right to buy, and how the share is valued.
• What happens if someone can't pay their part of the mortgage, or dies, or has a relationship breakdown.
• How disputes get resolved without forcing a sale of the whole property.

The figure below shows how the pieces fit together: each buyer brings their own KiwiSaver withdrawal and deposit share, the title records each person's percentage as tenants in common, and the sharing agreement sits over the top as the rulebook.

A property-sharing agreement is a legal document. Smiths Financial does not provide legal advice — please have a property lawyer prepare and explain it. Where we can help is making sure the financial protection around it holds up, which is the next section.

What happens if one owner wants out, or can't pay?

This is the scenario most groups underprepare for, and it is where a sharing agreement earns its keep. Three situations come up often.

Someone wants to sell their share. Without an agreement, an owner who wants out may be able to force a sale of the whole property through the courts. A sharing agreement usually gives the remaining owners the first right to buy the departing owner's share at an agreed valuation method, so one person leaving does not put everyone's home at risk.

Someone can't pay their part of the mortgage. The bank holds all owners jointly liable for the full loan, regardless of the agreed split. If one person stops paying, the others have to cover the whole repayment or risk default. An agreement can set out how a shortfall is shared, how a defaulting owner's share is adjusted, and what triggers a buy-out — but the agreement does not change the bank's right to pursue any owner for the full debt.

An owner dies. Under tenants in common, the deceased owner's share passes under their will, which could mean their share goes to someone outside the group — a partner, a child, an estate. The surviving owners may suddenly co-own with a stranger, or face pressure to buy out the share. This is where ownership structure, a will and insurance all need to line up.

Because the bank can pursue any owner for the full mortgage, the financial backstop for "can't pay" and "dies" usually comes down to insurance on each owner's life and income. That is the final piece.

Protecting a co-owned home with the right insurance

When several people share one mortgage, each person is relied on to keep paying their part, and each is legally exposed to the others' parts. Insurance is what stops one person's death or illness from forcing a sale that the whole group did not choose. The starting question is usually which cover to put in place first, which we work through in protecting a new mortgage: which cover first.

Two products do most of the work for a co-owned home:

Whether a claim is paid depends on the terms, conditions, exclusions, stand-down periods and underwriting of the specific policy, and on the disclosure made when the cover was taken out. This is a summary only — always read the policy wording or product disclosure statement.

For a group, cover is usually structured so each owner's life is insured for at least their share of the mortgage, with the proceeds set up to repay the loan rather than fall into a general estate. How that is arranged interacts with the ownership structure and each person's will, so it is worth coordinating insurance, title and legal advice together rather than in isolation. We compare cover across the major New Zealand insurers rather than offering an in-house product. We're generally paid by commission from the insurer when you take out a policy through us; this doesn't change the premium you pay. We manage any conflicts of interest in line with our duty to prioritise your interests — full details are in our Disclosure.

Your co-buyer's checklist

01. Confirm each co-buyer's KiwiSaver join date and check who has cleared 3 years' membership. ¹

02. Get each person's balance and subtract $1,000 each to find the true combined withdrawable deposit. ²

03. If any co-buyer has owned a home before, check the second-chance pathway and start the Kāinga Ora step early. ⁴

04. Decide with a lawyer whether to hold the title as joint tenants or tenants in common, and record any unequal shares. ⁷⁸

05. Have a lawyer draft a property-sharing agreement covering exit, default, death and disputes.

06. Put life and income cover on each owner so one person's death or illness doesn't force a sale.

Frequently asked questions

Can each person buying together use their own KiwiSaver? In most cases, yes. The first-home withdrawal is assessed per member, so each eligible co-buyer applies individually through their own provider. Each must have at least 3 years' membership and leave $1,000 in their account. ¹²

Should we own the house as joint tenants or tenants in common? Couples often use joint tenants, where a deceased owner's share passes automatically to the survivor. Family and friend groups more often use tenants in common, where each person holds a defined share that passes under their will. Which suits you is a legal decision — talk to a property lawyer. ⁷⁸

Do we need a property-sharing agreement? For family or friends buying together, a written agreement drawn up by a lawyer is widely recommended. It sets out shares, who pays what, and what happens if someone wants to sell, can't pay or dies — before any of those happen. Smiths Financial does not provide legal advice on this. ⁸

What if one of us has owned a home before? They may still qualify through the second-chance pathway. Kāinga Ora first decides whether they are in the same financial position as a first-home buyer; they must not currently own property and must have realisable assets below 20% of the area's house-price cap. ⁴

Is the First Home Grant still available for groups buying together? No. The First Home Grant stopped accepting applications from 22 May 2024 and is no longer available to anyone. The Kāinga Ora First Home Loan, which allows a 5% deposit, is still available, subject to income caps including a $150,000 combined cap for two or more buyers. ⁵⁶

Why would each owner need life insurance? The bank can pursue any owner for the full mortgage, not just their share. If one owner dies without cover, the others may have to cover a larger loan or sell. Life cover on each owner can repay that person's share so the survivors keep the home. Cover depends on the policy terms and disclosure. ⁸
