Want to buy an investment property in New Zealand with a 10% or 20% deposit? The minimum deposit for an investment property in NZ depends on the property type, lender, LVR rules, your income, existing debt, equity position, and the strength of your overall application.
As a general guide, many property investors buying an existing rental property through a bank should expect to need around a 30% deposit. Some banks or lenders may require more depending on the deal, the borrower, and the property.
However, a 10% or 20% deposit may still be possible in some situations. The pathway depends on the property and lender: some qualifying construction or new-build transactions may receive different LVR treatment, while some specialist or non bank lenders may consider lower-deposit investment lending. Usable equity can help provide the required contribution, but it does not reduce the deposit percentage itself.
This guide explains when a lower deposit may be possible, why banks usually ask investors for larger deposits, and how Platinum Mortgages can help you understand your options before you start making offers.
Meeting a deposit figure does not guarantee mortgage approval. The lender must also assess income, expenses, existing debt, credit conduct, rental income, debt-to-income position and the proposed property.
For many existing investment properties, a bank may expect around a 30% deposit. A lower deposit may still be possible, but it depends on the property, lender, current LVR settings and the strength of the complete application.
The table below is a practical guide rather than a promise of approval.
| Indicative contribution | Where it may arise | What still needs to be checked |
|---|---|---|
| Around 30% | Common starting point for an existing investment property through a bank | Servicing, DTI, property acceptability, credit and lender policy |
| Around 20% | May be considered in some stronger or differently structured applications | Whether the lender has an available pathway and the complete application fits |
| Around 10% | Usually limited to specific circumstances, such as some qualifying construction or new-build transactions | Eligibility, pricing, fees, conditions and whether the complete application remains suitable |
The correct question is not only “How much deposit do I need?” It is also “Which lender, property and structure may realistically fit my complete position?”
Banks generally take a more conservative approach to investment-property lending than to owner-occupied lending. The deposit they require can vary depending on the borrower, the property and the bank’s own lending criteria.
Deposit is only one part of the assessment. Debt-to-income restrictions may also affect how much an investor can borrow even where the required deposit is available.
For more detail, read our guide to Debt-to-Income Ratios in New Zealand.
Under the current Reserve Bank framework, investor lending above 70% LVR is classified as high-LVR lending. Banks may currently allocate up to 10% of their new investor lending above that threshold.
These are bank portfolio limits, not an entitlement for an individual borrower. Banks may apply stricter lending criteria.
A 70% LVR broadly corresponds to a 30% borrower contribution. However, the final calculation depends on the property value accepted by the lender, the properties used as security and the approved loan amount. For the official current settings and exemptions, see the Reserve Bank’s LVR restrictions.
| Borrower contribution | Contribution amount | Indicative lending required |
|---|---|---|
| 10% | $70,000 | $630,000 |
| 20% | $140,000 | $560,000 |
| 30% | $210,000 | $490,000 |
The table shows the arithmetic only. It does not establish whether a lender will approve the proposed amount or accept the particular property.
Not sure whether a 10%, 20% or 30% contribution is realistic for your situation? Platinum Mortgages can assess the proposed property, your available contribution and the lending pathways that may be available before you rely on a particular deposit figure.
TALK TO AN INVESTMENT PROPERTY ADVISER
There is no single lower-deposit pathway that works for every investor. The options depend on the property being purchased, the source of the contribution, the lender and whether the complete application meets lending requirements.
A 20% deposit may be possible, but it is not the standard answer for every existing residential investment property.
A lender may be more willing to consider the application where the borrower has strong income, manageable existing debt, good credit conduct, appropriate cash reserves and a property the lender is comfortable accepting as security.
The lender must still decide whether the application fits its available LVR capacity, servicing model, DTI position and wider lending policy.
A 10% investment-property contribution is a narrower pathway and should not be presented as routinely available.
It may be possible in limited circumstances, depending on the property, lender and complete application. Higher-leverage lending can also leave less room for unexpected costs or changes in interest rates.
The relevant comparison is the total lending outcome, not the headline deposit percentage alone.
Qualifying construction lending can be exempt from the standard Reserve Bank LVR restrictions. This can include certain purchases of newly built homes from the developer within six months of completion, subject to the Reserve Bank exemption requirements.
This can create lower-deposit possibilities in some circumstances, but it does not mean every new build can be purchased with a 10% deposit.
The lender may still assess the development, valuation, construction stage, settlement timing, borrower contribution, affordability and its own new-build policy.
Lenders can also apply their own definitions and criteria. Before relying on a lower contribution, confirm that the particular property and transaction qualify under the selected lender’s current rules.
Angela Downie, Financial Adviser at Platinum Mortgages, explains:
“One example that comes to mind is a client from Auckland who wanted to purchase a turnkey investment property in Christchurch. The purchase price was around $600,000, and he had an $80,000 deposit, around 13%.
He had been with the same employer for over three years, had a strong PAYE income, and the property had a rental appraisal of around $600 per week, which helped support the application.
He initially approached one mainstream bank, but they weren’t able to help because the application did not fit their lending policy at the time. We reviewed the position and another mainstream bank subsequently approved lending of around $520,000.
It is a good example of how one lender saying no does not necessarily mean every lender will reach the same decision. In the right circumstances, buying an investment property with less than a 20% deposit can be possible, but it depends on the borrower, the property and the complete application.”
A 20% deposit does not always need to come from cash savings.
If you already own a property, usable equity may be available to provide some or all of the contribution for an investment-property purchase.
The amount of deposit required and the source of that deposit are two different questions. Using equity may help provide the contribution, but it does not change the required deposit percentage or remove the lender’s normal approval requirements.
For a detailed explanation, see Using Equity to Buy an Investment Property in New Zealand.
A specialist or non bank lender may sometimes consider an investment-property purchase that does not fit ordinary bank deposit or policy settings.
This pathway still requires an assessment of affordability, equity, total debt, credit conduct and property security.
A lower contribution should never be treated as automatic approval or as the cheapest option. Before proceeding, understand the interest rate, fees, loan term, affordability, risks and proposed exit strategy.
For the broader specialist-lending process, see Platinum Mortgages’ non bank lending options.
Deposit and LVR answer only one part of the application.
A lender must still be satisfied with affordability, existing debt, credit conduct, rental-income treatment, DTI and the proposed property.
For the complete approval assessment, read how lenders assess an investment property mortgage.
Before relying on a 10%, 20% or 30% deposit figure, confirm:
No. Around 30% is a useful starting point for many existing-property bank applications, but property type, lender policy and the complete application can produce a different result.
KiwiSaver first-home withdrawal rules require an eligible buyer to intend to live in the property. They cannot be used for a standard investment-property purchase. Confirm your eligibility with your KiwiSaver provider where relevant.
Potentially. A genuine gift, family loan or other family-supported contribution may be treated differently by lenders.
The source of the money, any repayment expectations, documentation and the effect on affordability need to be disclosed and assessed.
A larger contribution can reduce the LVR and proposed debt, but it does not solve every servicing, DTI, credit or property-policy issue.
Sometimes, but not automatically.
A non bank lender will still assess affordability, equity, property security, credit, risk, costs and the proposed exit strategy.
If you’re planning an investment-property purchase, Platinum Mortgages can help you establish what contribution may be realistic, whether a lower-deposit pathway may be available for the proposed property, and which lending options are worth assessing before you make an offer.
