Frequently Asked Questions
Enter your loan amount, interest rate, loan term, and payment frequency into the calculator. The tool will instantly calculate your weekly, fortnightly, or monthly repayments, plus total interest costs over the life of the loan.
As of 2025, NZ mortgage rates typically range from 6.0% to 7.5% depending on the term (fixed vs floating) and your loan-to-value ratio (LVR). Check our comparison page for current live rates from major banks.
Weekly or fortnightly payments can save you interest over the life of the loan because you make slightly more repayments per year (52 weeks vs 12 months). Many NZ homeowners prefer fortnightly payments aligned with their pay cycle.
Most NZ banks require at least a 20% deposit to avoid low equity premiums. First home buyers may qualify for low deposit loans (10% or less) through schemes like the First Home Loan or by using KiwiSaver funds.
Fixed rates lock in your interest rate for a set period (6 months to 5 years), providing payment certainty but charging break fees if you pay off early. Variable (floating) rates change with market conditions but offer flexibility for extra repayments without penalties.
You can reduce repayments by: (1) Refinancing to a lower interest rate, (2) Extending your loan term (though this increases total interest), (3) Making extra lump sum payments to reduce principal, or (4) Using an offset account to reduce interest charged.
