First Home Buyer · 3 August 2026
What the bank needs when family helps with your deposit, and why the same money is judged very differently by the lender, by relationship property law, and by Work and Income.
In this article
Yes. New Zealand banks accept gifted deposits, and family help is now one of the most common ways first home buyers reach a deposit at all. What the lender wants is proof that the money is a genuine gift with no expectation of repayment, which is usually a signed gifting certificate or statutory declaration from whoever is giving it. There is no gift duty to pay: it was abolished for gifts made on or after 1 October 2011 (Source: Inland Revenue).
That is the easy part, and it is where most explanations stop. The harder and more useful question is which form the family help should take, because a gift, a family loan and a guarantee are three genuinely different arrangements. They affect your borrowing power differently, they sit differently if a relationship later ends, and they land differently on the person doing the helping. The awkward part is that no single option is best on all three counts.
Families often use these words interchangeably at the kitchen table. Lenders and lawyers do not. Here is what separates them.
| Arrangement | What actually happens | The trade-off |
|---|---|---|
| Gift | Money handed over for good, documented as non-repayable. | Cleanest for the loan application, least protection for the giver. |
| Family loan | Money lent, usually recorded in a deed of acknowledgement of debt. | Keeps the money traceable, but it is a debt the lender will want to know about. |
| Guarantee | No cash changes hands; family property is offered as extra security. | Family keeps its savings, but puts its own property on the line. |
A guarantee is a different animal again, and it can remove the low equity margin on a small deposit entirely. We cover how that works alongside the other routes in low deposit home loans in NZ. This article stays with the money that actually moves.
Lenders are not suspicious of gifts, they are suspicious of undocumented money. Their concern is simple: if the deposit has to be repaid to someone, that repayment competes with the mortgage they are about to write. So they ask for three things.
A letter or statutory declaration from the person gifting, confirming the amount and that no repayment is expected. Some lenders have their own form. Because it is a formal declaration, it is worth the giver taking their own legal advice before signing.
Banks need to see where the money came from and follow it into your account. Money that appears shortly before settlement with no history behind it creates delays, so gifts are far smoother when they land early and cleanly.
Many lenders like to see that part of the deposit is yours, whether that is savings or a KiwiSaver first home withdrawal. How much, and whether it applies at all, varies by lender and by the size of the gift.
If the family expects the money back one day, it is a loan, and it belongs in the application as a loan. Declaring a gift while privately treating it as a loan misstates your position to the lender, and it leaves the family with nothing in writing either.
In our experience at Trebla, the gifting certificate is rarely what holds an application up. What holds it up is a large sum arriving in an account a fortnight before settlement with no explanation attached, and a family that has not yet decided among themselves whether it was really a gift. Both are avoidable with a conversation early on.
Here is the part that gets missed. The bank has a clear preference, and it is an honest one: a gift is simpler for the loan, so a gift is what it will encourage. But the bank is only assessing its own risk. Two other systems judge the same dollar, and both of them lean the other way.
Money gifted to a couple, or gifted to one person and then mixed into a jointly owned home, can end up treated as shared property. Money properly recorded as a loan back to the family is generally a debt of the relationship instead. This is why families who want the money to stay in the family often prefer a documented loan, and why it needs a lawyer rather than a template.
Work and Income applies gifting limits when it asset tests for the Residential Care Subsidy. It will not count up to $8,500 of assets gifted each year in the five years before an application, a total of $42,500 across that window between a person and their partner, and up to $27,000 a year for gifts made more than five years earlier (Source: Work and Income). A deposit gift is usually well above those figures, so it can be counted in an assessment years down the track.
None of this is a reason to turn down family help. It is a reason to decide the form of it before the certificate gets signed, because changing the structure after settlement is difficult and sometimes impossible.
The last thing to know is that a gift does not simply scale up what you can buy. Your borrowing limit is the lowest of three separate ceilings: your deposit and the resulting loan-to-value ratio, the debt-to-income limits, and the bank's own test of whether you can afford the repayments. A gift raises the first ceiling. It does nothing to the other two.
That matters because most owner-occupier lending is capped at six times gross income (Source: RBNZ), and the servicing test is run on your income, not your parents'. A generous gift can move you from a low deposit to a comfortable one, which is genuinely valuable and often removes the low equity margin. What it cannot do on its own is push the loan past the income ceilings. Buyers are sometimes surprised that a much larger gift did not translate into a much larger approval, and this is why.
You can test where your own ceilings sit with our house deposit calculator and LVR and DTI calculator, and the full picture is set out in how much you can actually borrow in NZ. If a gift is part of your plan, it is worth mapping all three ceilings before you decide how much family help you actually need.
Yes. NZ banks accept gifted deposits, and family help is one of the most common ways first home buyers reach a deposit. The lender will want the money documented as a genuine gift, usually through a signed gifting certificate or statutory declaration confirming there is no expectation of repayment. Lender policies differ on how much of the deposit can be gifted and whether they also want to see some of your own savings.
No. A gift is money given with no expectation of repayment, and that is exactly what the gifting certificate confirms to the lender. If the family expects the money back one day, it is not a gift, it is a loan, and it needs to be documented and disclosed as one.
No. Gift duty was abolished for gifts made on or after 1 October 2011 (Source: Inland Revenue), so there is no duty to pay on a deposit gift. That does not mean gifting has no consequences elsewhere: Work and Income's asset testing for the Residential Care Subsidy still looks at what has been gifted and when.
It can. A gift adds to your deposit and leaves your income untouched. A family loan is a debt, so lenders may count the repayment obligation in their servicing assessment, which can reduce the amount they will lend. Treatment varies by lender and depends on the terms, so it is worth checking before the structure is locked in.
That depends on how it was given and documented. Money gifted to a couple, or gifted to one partner and then mixed into a jointly owned home, can end up being treated as shared property. Money recorded as a loan back to the family is generally a debt of the relationship instead. This is a legal question with real consequences, so families usually have a lawyer document the arrangement before settlement.
It can. Work and Income will not count up to $8,500 of assets gifted each year in the five years before an application, a total of $42,500 across that period between a person and their partner, and up to $27,000 a year for gifts made more than five years before applying (Source: Work and Income). A deposit gift is often larger than those allowances, so it can be counted in an assessment years later.
