Break Fee Warning

If you're on a fixed rate, ask your current bank for a break fee quote before refinancing. Break fees can be substantial and may outweigh the savings from a lower rate.

Refinancing FAQs

Is it worth refinancing my mortgage NZ?

Refinancing is worth it if you can save at least 0.5% on your interest rate and plan to stay in your home for 2+ years. Factor in break fees, legal costs, and any cashback offers.

What are mortgage break fees in NZ?

Break fees apply when you exit a fixed rate early. They compensate the bank for lost interest and can range from a few hundred to tens of thousands of dollars depending on the rate difference and time remaining.

How much can I save by refinancing?

A 0.5% rate reduction on a $500,000 loan saves approximately $200/month or $2,400/year. Over the life of the loan, this can total $50,000+ in savings.

Should I take a bank cashback offer?

Cashback offers (typically $2,000-$5,000) can help offset switching costs, but check if the rate is competitive. Sometimes a lower rate without cashback saves more long-term.

How often can I refinance my mortgage?

You can refinance as often as you like, but it's usually only worthwhile every 2-3 years when fixed terms expire. Switching during a fixed term incurs break fees.
