What Is LMI and Do Canterbury Buyers Need It

Lenders Mortgage Insurance (LMI) is a product common in Australia that many Canterbury buyers - particularly those relocating from Australia - wonder about. Here is how New Zealand handles the equivalent risk and what it means in practice.

How LMI Works in Australia

In Australia, borrowers who purchase with a deposit below 20% typically pay LMI - a one-off insurance premium that protects the lender (not the borrower) if the borrower defaults. LMI premiums can run into the thousands or tens of thousands of dollars depending on the loan amount and LVR ratio. It is a significant upfront cost that many Australian first home buyers factor into their deposit planning.

New Zealand's Different Approach

New Zealand does not use LMI in the same way. Instead, the Reserve Bank of New Zealand uses Loan-to-Value Ratio (LVR) restrictions to manage the risk of high-LVR lending. Rather than charging borrowers an insurance premium, the RBNZ limits how much high-LVR lending banks can make as a proportion of their total new lending. Banks are allowed to make up to 25% of new owner-occupier lending to borrowers with deposits under 20% (from December 2025). This means a Canterbury buyer with a 10-15% deposit may be able to borrow without paying an LMI-equivalent premium - but they need to be within the bank's speed limit allocation for low-deposit lending.

The Kainga Ora First Home Loan Approach

For eligible Canterbury first home buyers with a 5% deposit, the Kainga Ora First Home Loan eliminates the need for LMI by having Kainga Ora underwrite the risk on behalf of the government. The buyer does not pay a premium - the government absorbs the risk. This is the closest New Zealand equivalent to LMI avoidance, and it makes the First Home Loan significantly cheaper than the Australian LMI model for equivalent LVR levels.

The Practical Implication

Canterbury buyers with less than 20% deposits should explore: the Kainga Ora First Home Loan (5% deposit, income caps apply, no house price cap); standard bank lending within the speed limit allocation (10-20% deposit); and new build purchases (no LVR restriction, 20% deposit sufficient).
