Quick answer: Usually not with 20% — but yes, in several situations. New builds are generally exempt from Reserve Bank LVR restrictions and typically need around 20% deposit; equity in your existing home can often replace a cash deposit; and since December 2025, banks have more room to lend to investors with 20–30% deposit on existing properties. Current as of July 2026 — RBNZ last adjusted LVR settings 1 December 2025.
How much of an Auckland investment property deposit do you actually need? Most people assume the rules work like they do for your own home. They don’t. And the gap between “what most lenders require” and “what’s actually possible” is where a lot of would-be Auckland investors either miss an opportunity or spend months saving for a deposit they may not need.
Every week I speak with Auckland investors who assume they need a 30% deposit when, in some situations, there may be other options worth exploring. Let’s break down where the numbers really sit, and the situations where a lower deposit — or no cash deposit at all — may be possible.
The Auckland investment property deposit most investors don’t expect
For a standard existing property, the Auckland investment property deposit most lenders require is around 30%, driven by the Reserve Bank’s LVR (loan-to-value ratio) restrictions.
In short, the LVR rules cap how much low-deposit lending a bank can do. For investors buying existing property, lending above 70% of the property’s value is tightly restricted, so in practice most lenders ask for around 30% equity. That’s the baseline to plan around — and it’s why the “20% is enough” assumption trips people up.
Good to know: LVR settings are set by the Reserve Bank and change from time to time. Current as of July 2026 — RBNZ last adjusted these settings 1 December 2025. Always confirm the latest position before making decisions. See the Reserve Bank of New Zealand’s LVR information.
Can you use equity instead of cash?
Many Auckland investors don’t save a cash deposit at all. Instead, they use the equity in their existing home as security for the investment loan. If your home has grown in value — or you’ve paid down a meaningful portion of your mortgage — that built-up equity can potentially do the job a cash deposit would.
Whether this is possible depends on three things: how much usable equity you have (lenders calculate this against a portion of your home’s value, not the full amount), your income and ability to service the larger combined borrowing, and the lender’s overall assessment of your situation. It’s not automatic — but for homeowners, it’s frequently the most practical route into an investment property without having to touch your savings.
Tip: Usable equity is not simply your home’s value minus your mortgage. Lenders typically apply their own LVR limit to your home when calculating how much equity can be released. Subject to lender assessment and approval criteria.

Exception 1: New builds are generally LVR-exempt
This is the big one. New builds are generally exempt from Reserve Bank LVR restrictions — and from DTI restrictions too — although individual lenders may still apply their own lending criteria. The exemption exists because the government wants to encourage new housing supply.
What that means in practice:
- → An investor can often purchase a new build with around a 20% deposit, subject to servicing, income and lender approval — well under the 30% typically needed for an existing property.
- → In practice, this applies to turnkey purchases and certain construction/off-the-plan arrangements.
- → Because new builds also sit outside the DTI restrictions, the income test is generally more flexible too.
If you’ve been sitting on the sidelines because of the deposit gap, a new build is usually the first avenue worth exploring — subject to lender assessment and the specific property qualifying as a new build.
Exception 2: More room for existing properties too
Here’s something that’s genuinely moved in investors’ favour: from 1 December 2025, the Reserve Bank eased its LVR speed limit for investors, meaning banks can now do more of their lending to investors sitting at 20–30% deposit on existing properties (up from a smaller allowance previously).
A live lender deal worth knowing about
Separately — and this is more lender-specific than a blanket rule — at least one major lender currently has a live deal offering lending up to 90% LVR (as low as a ~10% deposit) on existing investment properties, subject to a debt-to-income ratio under 7×. Deals like this are lender-specific, apply to live/current applications only, and can open or close without notice — so it’s the kind of thing worth checking directly with an adviser rather than assuming it applies to you.
A few important caveats either way, because honest expectation-setting matters:
- → Lower-deposit lending on existing properties is allocated within each bank’s own lending quota and can be withdrawn or tightened at any point.
- → The servicing rules stay strict. A debt-to-income (DTI) limit of 7× applies to most investor lending, and lower-deposit loans don’t get an easier ride on this test — your income relative to total borrowing still has to stack up.
- → Additionally, standard responsible-lending and lender approval criteria still apply, and further assessment will be required.
Important: This may provide an opportunity for some investors, but it’s narrow and lender-dependent. Whether it fits depends heavily on your income, existing debts and the numbers stacking up under the DTI test. All lending is subject to lender assessment and approval criteria, and lender policies can change at any time. Current as of July 2026.
A worked DTI example
DTI (debt-to-income) is the other half of the equation alongside deposit. For investors, the general rule of thumb is:
Gross annual income × 7 = indicative maximum total borrowing.
Example: $150,000 gross income × 7 = $1,050,000 maximum total debt (including this loan and any other debt).
New builds sit outside this DTI test entirely — which is one more reason they’re often the more flexible option. Indicative only; rental income treatment, existing debt and lender policy all affect the real number.
So — can your investment property deposit be under 20%?
Yes, in several situations:
- 1. New build — generally exempt from LVR and DTI restrictions, often achievable from around a 20% deposit, subject to lender criteria.
- 2. Equity from your existing home — can replace a cash deposit for many homeowners, subject to usable equity, income and lender assessment.
- 3. Existing property at 20–30% deposit — more achievable since the December 2025 easing, with at least one lender’s live deal currently going as low as ~10%, subject to DTI under 7×.
For a standard existing property outside those situations, plan for an investment property deposit of around 30%. The right path depends on your deposit, your income, the property type, and which lender’s criteria you fit — so it’s worth mapping out properly before you start house-hunting.
What that looks like in numbers
| Property type | Purchase price | Indicative deposit |
|---|---|---|
| Existing investment property | $800,000 | ~$240,000 (30%) |
| Qualifying new build | $800,000 | ~$160,000 (20%) |
| Existing property, post-Dec 2025 easing | $800,000 | ~$160,000–$240,000 (20–30%) |
| Existing property, live lender deal* | $800,000 | ~$80,000 (10%), subject to DTI <7× |
| Using home equity (existing or new build) | $800,000 | No cash required — subject to usable equity and lender assessment |
