The Deposit Question Every NZ Property Investor Asks First
Before you can start building a property portfolio in New Zealand, you need to understand one fundamental question: how much deposit do you actually need? The answer depends on several factors — the type of property, your lending situation, and whether you qualify for any low-deposit schemes.
Getting this right from the start can save you months of unnecessary saving and set you on the fastest path to your first investment property.
The Standard Deposit Requirement: 35%
For most residential investment properties in New Zealand, banks require a minimum deposit of 35% of the property’s purchase price. This is due to RBNZ (Reserve Bank of New Zealand) loan-to-value ratio (LVR) restrictions specifically applied to investment properties.
So on a $700,000 investment property, you would need:
- 35% deposit: $245,000
- 65% mortgage: $455,000
This is significantly higher than the 20% typically required for owner-occupied homes, which reflects the additional risk lenders associate with rental properties.
New Builds: A Lower Deposit Option
One of the most important distinctions in New Zealand investment property lending is the treatment of new builds. New build investment properties are often exempt from the standard 35% LVR restriction, meaning investors may be able to purchase with as little as 20% deposit — and in some cases, even less.
This makes new builds particularly attractive for investors who want to enter the market sooner or spread their capital across multiple properties. Key new build advantages include:
- Lower deposit requirements (often 20% or less)
- Depreciation benefits for chattels (appliances, carpets, etc.)
- Lower maintenance costs in the early years
- Compliance with current building codes (insulation, moisture barriers, etc.)
- Potentially stronger capital growth in developing areas
Using Equity From Your Existing Home
Many New Zealand property investors don’t save their deposit in cash — they use equity from their own home. If your home is worth more than what you owe on your mortgage, you may be able to use that difference as a deposit for an investment property.
For example, if your home is worth $900,000 and you owe $400,000, you have $500,000 in equity. Banks will typically lend up to 80% of your home’s value, which in this case gives you access to $320,000 in usable equity ($900,000 x 80% = $720,000, minus the $400,000 owed).
Using equity is one of the most powerful tools available to property investors and is how many multi-property portfolios are built over time.
The Total Cash You Need: Beyond the Deposit
When budgeting for your investment property deposit, remember that the deposit is not the only upfront cost. You should also budget for:
- Legal fees: Typically $1,500–$3,000 for a standard purchase
- Building inspection: $500–$1,000
- LIM report: $200–$400
- Mortgage fees: Varies by lender
- Moving and setup costs: If you need to furnish or make any initial improvements
How Much Deposit Do You Need for Different Property Prices?
Here’s a quick reference for standard 35% deposit requirements at different price points:
- $500,000 property: $175,000 deposit
- $600,000 property: $210,000 deposit
- $700,000 property: $245,000 deposit
- $800,000 property: $280,000 deposit
- $1,000,000 property: $350,000 deposit
For new builds with 20% deposit:
- $600,000 property: $120,000 deposit
- $700,000 property: $140,000 deposit
- $800,000 property: $160,000 deposit
Can You Use KiwiSaver for an Investment Property?
No. KiwiSaver first home withdrawal is only available for owner-occupied properties — not investment properties. However, KiwiSaver can still play an indirect role in your investment strategy by helping you buy your first home with a lower deposit, which can then build equity faster that can be used for future investment property purchases.
Stress Testing Your Investment: Can You Afford the Mortgage?
Having the deposit is only half the equation. Banks will also assess your ability to service the investment mortgage — typically stress testing it at a higher rate than the actual mortgage rate to account for potential rate increases.
As a general guide, most investors need rental income covering at least 75% of the mortgage repayments to satisfy servicing requirements, with the balance covered by other income. However, lending criteria varies significantly between banks, which is why working with a mortgage broker who specialises in investment property is strongly recommended.
Research Property Values Before You Invest
One of the most important steps before investing is understanding what properties are genuinely worth in the areas you’re considering. Use Estim8 to research recent sales data, suburb price trends, and property estimates across New Zealand — so you invest with confidence, not guesswork.
Knowing the real value of a property protects you from overpaying and helps you identify genuine investment opportunities in today’s market.
