Investment properties in New Zealand are subject to stricter LVR (Loan-to-Value Ratio) restrictions than owner-occupier properties. Understanding these rules is essential before planning any property investment.
Current LVR Limits for Investors
The Reserve Bank of NZ sets the following limits for residential investment property lending:
| Property type | Maximum LVR | Minimum deposit |
|---|---|---|
| Existing residential (investor) | 65% | 35% |
| New build (investor) | 80% | 20% |
| Owner-occupier (existing) | 80% | 20% |
| Owner-occupier (new build) | 90% | 10% |
The investor limits are significantly more restrictive than owner-occupier limits — a deliberate policy designed to reduce speculative investment lending.
Why Do Investors Face Stricter LVR Rules?
The RBNZ imposed investor-specific LVR limits because:
- Investor lending is more procyclical — investors tend to buy in up-markets and sell (or default) in down-markets, amplifying price swings
- Investors can tolerate higher LVR risk in theory (they have rental income), but in practice, investment properties are the first casualties in a market downturn
- Leveraged investor demand was identified as a driver of the 2020–2022 housing price surge
- Macro-prudential management — the RBNZ uses LVR limits as a tool to manage housing market risk and bank exposure
From the bank’s perspective: a higher deposit reduces the chance of negative equity if property prices fall, protecting the bank’s security.
The 35% Deposit Requirement — What It Means in Practice
For a $700,000 investment property:
- Required deposit: 35% = $245,000
- Maximum loan: 65% = $455,000
For a $900,000 investment property:
- Required deposit: 35% = $315,000
- Maximum loan: 65% = $585,000
The 35% requirement makes property investment accessible primarily to those who have either:
- Already accumulated significant savings/assets, or
- Built equity in an existing property (their home or a previous investment) to use as a deposit
Using Existing Property Equity as a Deposit
The most common way investors fund a 35% deposit is by using the equity in their own home.
Example:
- Home value: $900,000
- Home mortgage: $350,000
- Home equity: $550,000
- Maximum equity release (to 80% LVR on home): $900,000 × 80% = $720,000 − $350,000 = $370,000 available
The investor can use this equity release to fund the 35% deposit on an investment property. They increase their home mortgage to $720,000 and use the released $370,000 as the deposit on an investment property worth up to $1,057,000 (35% = $370,000).
Cross-Collateralisation vs Stand-Alone Investment Mortgage
When using home equity to fund an investment, there are two structures:
Cross-collateralisation: The bank takes security over both properties under one mortgage. Simpler to arrange, but riskier — the bank can act against your home if the investment property defaults, and refinancing or selling either property requires bank approval for both.
Stand-alone investment mortgage: The home is refinanced to release equity (the equity is drawn as cash), and the investment property mortgage is separately arranged (possibly with a different bank). The bank lending on the investment property only has security over that property. More complex but avoids cross-collateralisation risk.
Most property investment advisers recommend separate mortgages where possible.
New Build Exemption: 20% Deposit
New builds are exempt from the investor 65% LVR restriction. An investor can purchase a new build with a 20% deposit instead of 35%.
On a $700,000 new build:
- Required deposit: 20% = $140,000 (vs $245,000 for existing property)
- Loan: 80% = $560,000
This is a significant advantage — $105,000 less capital required for the same property value. It’s one reason investors have been attracted to new build developments.
LVR and the Investment Portfolio
When calculating LVR for investment purposes, each property is assessed individually rather than as a portfolio — but banks look at your total debt and income (DTI) when deciding whether to lend on additional properties.
As your portfolio grows, the DTI limit becomes the binding constraint. With a 6× DTI limit and $130,000 income, the maximum total debt across all properties (personal home included) is $780,000.
See Investment Property Mortgage NZ for the full DTI analysis.
Can the LVR Limits Change?
Yes — the RBNZ reviews LVR limits periodically and adjusts them based on housing market conditions and financial system risk. Historically:
| Period | Investor LVR limit |
|---|---|
| Pre-2015 | No formal investor LVR restriction |
| 2015 | 70% (investor LVR introduced) |
| 2016 | 65% (tightened) |
| 2018 | 65% (eased slightly for owner-occ, investors unchanged) |
| 2021 | 65% (reduced from 70% back to 65% after brief easing) |
| 2026 (current) | 65% (no recent change) |
Banks are allowed to lend up to 5% of their new investment property lending above 65% LVR (similar to the owner-occupier high-LVR allowance). In practice, this is rarely extended to standard investment property borrowers.
