Bank of Mum and Dad: Is Gifting a Deposit the Best Way to Help Your Kids?
When you look at the current New Zealand property market, it is no secret that saving for a first home deposit in New Zealand is one of the biggest hurdles facing the next generation. As a parent, if you have worked hard and are in a position to help, stepping in as the "Bank of Mum and Dad" is an incredibly generous milestone.
Naturally, most families default to the easiest option: gifting the deposit.
It sounds simple, clean, and loving. You transfer the funds, your child buys the home, and everyone celebrates. But when family emotions collide with property law, a simple cash gift can inadvertently expose your hard-earned wealth to long-term risks you might not have anticipated.
Before you sign any paperwork, it is vital to understand the operational difference between a Gifted Deposit and a Deed of Acknowledgement of Debt—and crucially, how banks and property laws view each one.
The Two Paths: Gifts vs. Deeds of Debt
When advancing capital to help a child purchase a home, the transaction generally follows one of two legal frameworks.
1. The Gifted Deposit (The Unconditional Route)
This is a permanent, non-repayable transfer of wealth. To accept these funds as part of the home loan deposit, New Zealand banks will require you to sign a formal Gifting Certificate.
The Bank's Perspective: Lenders require this document to explicitly state that the money is an absolute gift with zero expectation of repayment, and that you hold no financial claim over the property. This ensures the bank has first priority over the asset if the mortgage hits trouble.
The Risk Factor: Once that certificate is signed, the money legally belongs entirely to your child. If they are purchasing the property with a partner or spouse, and that relationship unfortunately breaks down a few years later, those gifted funds are often classified as relationship property under the Property (Relationships) Act. Without a formal legal agreement (like a separate relationship property agreement), that capital could be split 50/50, leaving the household unit entirely.
2. The Deed of Acknowledgement of Debt (The Protected Route)
This is a specialized legal document drawn up by a solicitor stating that the advanced funds are a loan, not a free handout.
The Bank's Perspective: Under strict lending guidelines, banks are highly cautious about borrowed money being used to form a deposit. If a Deed of Debt states that your child must make regular weekly repayments or pay ongoing interest to you, the bank will count those payments as a financial liability, which can significantly reduce their borrowing power or mean it won't count toward their deposit altogether.
The Strategic Solution: To satisfy bank criteria, the Deed of Debt is typically structured to be completely interest-free, with no regular principal repayments required. Instead, the document states that the loan is only repayable under specific future triggers, such as when the property is eventually sold. The bank will still require their mortgage to take absolute priority, but they will generally accept this structure because it doesn't impact your child's day-to-day cash flow.
The "Genuine Savings" Fork in the Road
If you are buying a house with a lower deposit, the way the bank views your parents' contribution depends entirely on how much total equity you are bringing to the table. This is where the concept of Genuine Savings comes into play, and it splits applications into two distinct pathways based on your Loan-to-Value Ratio (LVR):
The Standard Low-Deposit Path (Under 20%): If your total deposit sits below the standard 20% threshold, banks often invoke a strict "Genuine Savings" policy. This means the bank requires at least 5% of the property's purchase price to have been accumulated personally by you over a 3-to-6 month window (usually demonstrated via your KiwiSaver first-home withdrawal or a steady history of personal bank savings). Under this rule, a parent's cash contribution cannot form that baseline 5% requirement—whether it is a gift or a Deed of Debt. However, once you have proven your own 5% genuine savings baseline, parents can absolutely use a Deed of Debt to inject additional funds on top to boost your overall deposit size.
The Standard Deposit Path (20% or More): Once your total deposit hits the 20% mark, the bank's strict "Genuine Savings" rules typically drop away. Because the loan is viewed as lower risk, the bank is completely comfortable if a significant portion or even all of that 20% comes directly from your parents. This opens the door perfectly for your solicitor to overlay a Deed of Debt to protect those family funds from day one, without the bank questioning where the cash originally accumulated.

Staying in Your Lane: The Legal Boundaries
It is incredibly important to note that while mortgage advisers deal with bank policies every single day, we are not lawyers, and we do not provide legal advice.
Property ownership, estate planning, tax settings, and relationship property laws in New Zealand are highly nuanced. Every family dynamic is completely unique. Before your child signs a Sale and Purchase Agreement, both you and your child should engage independent conveyancing solicitors. Your legal team will ensure that whatever path you choose is properly documented, protecting family relationships and financial assets cleanly.
Our role as financial advisers is to work alongside your legal professionals. Once your lawyer determines the right protective framework for your family, we step in to ensure the mortgage application is packaged perfectly for the banks so the loan progresses smoothly to approval.

A standard, transaction-focused mortgage broker might simply tell you to "just sign the gifting certificate" because it creates the fastest path to a quick bank approval.
