The Reserve Bank of New Zealand’s loan-to-value ratio (LVR) restrictions are the most significant regulatory constraint on home lending in New Zealand. They determine how much deposit you need, who can lend to you, and at what rates. For first home buyers especially, navigating LVR rules is often the biggest practical hurdle between renting and owning.
What Is LVR?
Loan-to-value ratio (LVR) expresses your mortgage as a percentage of the property’s value. If you are buying a $700,000 home with a $140,000 deposit, your LVR is 80% (you are borrowing 80% of the property value). Lenders and the RBNZ think about this as the inverse — your equity or deposit as a proportion of the purchase price.
The RBNZ sets rules on how much “high-LVR lending” (lending above 80% LVR for owner-occupiers, or above 65% for investors) banks are allowed to do. This doesn’t mean banks can never lend above these ratios — it means the percentage of their new lending that can exceed these ratios is capped.
Current LVR Limits (2026)
Owner-occupiers: Most banks require a minimum 20% deposit for standard residential mortgage approval. A small proportion of lending (currently 20% of new mortgage flows) can be approved with less than 20% deposit — this is called high-LVR lending. Borrowers with less than 20% typically pay a higher interest rate (a “low-equity premium”) and face more scrutiny.
Residential investors: Investment property purchases require a minimum 35% deposit. The RBNZ sets stricter limits for investors to reduce systemic risk and moderate house price inflation driven by investor demand.
New builds: New build properties are exempt from LVR restrictions, meaning banks can lend at higher LVR (lower deposit) for newly constructed homes. This is deliberate government policy to incentivise new housing supply.
The First Home Loan
The most important pathway for buyers who cannot reach 20% is the First Home Loan — a government-backed scheme administered by Kāinga Ora. It allows eligible first home buyers to purchase with as little as 5% deposit, with the government underwriting the high-LVR risk for the bank. Income and house price caps apply and vary by region.
Gifted Deposits and the Bank of Mum and Dad
Many first home buyers receive financial help from family. A gifted deposit — money given outright with no expectation of repayment — is generally accepted by NZ banks, but they require a signed gift letter confirming no repayment is expected. Parental guarantees (where a parent’s property is used as additional security) are another option, allowing the buyer to borrow with a smaller cash deposit while the parent’s equity covers the LVR shortfall.
Debt-to-Income (DTI) Rules
From 2024, RBNZ DTI limits mean most owner-occupiers cannot borrow more than 6 times their gross annual household income, regardless of deposit size. This is a separate constraint from LVR. A couple earning $150,000 combined has a maximum mortgage of approximately $900,000 under the DTI rules — though the bank’s own serviceability tests may produce a lower limit.
