New Zealand’s LVR (loan-to-value ratio) restrictions for residential investment properties are some of the strictest in the world. For most investors, the Reserve Bank’s current settings mean a 30% deposit on an existing property, or 20% for a new build. Understanding what these rules mean, and where the exceptions are, is the starting point for any property investment conversation.

What LVR Actually Means

LVR is the ratio of your loan to the value of the property. A $700,000 property with a $490,000 loan has an LVR of 70%. For residential investment properties, the RBNZ treats lending above 70% LVR as high-LVR and limits how much of it banks can write. In practice that means a 30% deposit for most existing investment properties, or 20% for a new build.

Owner-occupiers have more flexibility. First home buyers can sometimes access lending up to 90% LVR through specific schemes, and even standard owner-occupiers can sometimes borrow above 80% LVR through limited bank allocations.

Bank LVR limits don’t bind every lender, either. Some lenders sit outside the main bank restrictions and will consider investment lending with as little as a 10% deposit. The trade-off is usually a higher interest rate and tighter terms, but for the right deal it can be the difference between buying now and waiting — we’ll tell you honestly whether it stacks up.

Who Counts as an “Investor”

The classification matters. A property is treated as an investment property if you don’t intend to occupy it as your primary residence. This includes:

  • Rental properties (short or long-term)
  • Holiday homes you intend to rent out
  • Properties purchased for capital gain
  • Properties in a trust or company structure where you’re not the primary occupant

If you’re buying a property to live in, you’re treated as an owner-occupier — even if you’re an existing property investor.

DTI Ratios: The New Constraint

In 2024, the RBNZ introduced Debt-to-Income (DTI) ratio restrictions as an additional lever alongside LVR. Banks are now limited in how much of their new lending can exceed certain DTI thresholds.

For investors, the DTI limit is typically 7x your total income. If your gross income is $150,000, your total debt (across all properties including your own home) generally can’t exceed $1.05 million under the DTI framework. This constrains how many properties experienced investors can hold as much as the LVR requirement constrains first-time investors.

How Lenders Assess Rental Income

When calculating whether you can service an investment loan, banks typically include a portion of the rental income — usually 75% of market rent — in their serviceability calculation. The 25% haircut accounts for vacancy, maintenance, and property management costs.

If you’re using interest-only repayments (which many investors prefer to maximise cash flow), lenders will still stress-test your ability to service the loan on a principal-and-interest basis at a test rate, which is typically 2% above the current rate.

Structuring Your Position

Many experienced investors use equity in their existing properties as the deposit for new ones. If your home has $400,000 of equity and you want to buy an investment property worth $800,000, you need a $240,000 deposit (30%), which could potentially be drawn from your home’s equity through a top-up.

However, cross-collateralising (using one property as security for another) requires careful thought. It links your properties together in a way that can constrain your flexibility later. Some investors prefer to keep properties on separate facilities at separate lenders.

The Bright-Line Test

The bright-line test taxes capital gains on investment properties sold within a certain period. As of 2024, the period is two years for properties acquired after 1 July 2024 (reduced from the previous 10 years). This doesn’t affect lending directly, but it should factor into your investment strategy. We’re not tax advisers and recommend speaking with an accountant about the tax implications of any property purchase.

Getting Investment Lending Right

Investment lending is genuinely more complex than owner-occupier lending. The right structure — which lender, which security arrangement, interest-only or P+I, fixed or floating — affects both your approval outcome and your long-term financial position. Working with an adviser who has personal investment property experience means you’re getting advice grounded in practice, not just theory.
