Investment Property Loans in NZ

Investment-property mortgages in NZ sit under tighter LVR rules than owner-occupier loans, and most banks apply higher servicing-test thresholds. The Coalition reinstated full interest deductibility for residential investment properties from 1 April 2025, restoring an important after-tax economic factor.

Key considerations

› RBNZ LVR investor rules: most banks require a 30% deposit (LVR ≤ 70%) for residential investment property — tighter than the 20% owner-occupier baseline.
› DTI rules apply to investor lending (current cap 7× household income; vs 6× for owner-occupiers). First-home buyers and new-builds are exempt.
› Interest on residential investment loans is fully deductible against rental income from 1 April 2025 onward (was being phased out under prior policy).
› Banks typically use a higher servicing test rate for investor loans (often the lender's standard test rate + a small loading).
› Brightline test is currently 2 years for residential property — affects taxation of sale gains within the period.

This website is operated by Evolve Group Limited (FSP711891), a Licensed Financial Advice Provider regulated by the Financial Markets Authority (NZ). The information published here is general in nature and is not personalised financial advice.

Rate accuracy. Rates shown across this site were observed at 21 May 2026, 12:27 pm from each lender's published carded-rate page (linked per row). If a lender has updated their rates since that timestamp, the authoritative source is the lender's page, not our derived snapshot. Carded rates are advertised rates — the rate you ultimately receive depends on your application.

CCCFA + Responsible Lending Code. Final lending decisions are made by the lender under the Credit Contracts and Consumer Finance Act 2003 and the MBIE Responsible Lending Code. Lenders apply servicing-test rates (typically around 8% post-2023), debt-to-income caps (RBNZ DTI 6× owner-occupier / 7× investor from 2024), and Loan-to-Value Ratio limits. Carded rates are not an offer or a pre-approval.
