1. Make Extra Repayments

Even small extra repayments can make a big difference over time. For example:

  • Paying an extra $50–$100 per week can shorten your mortgage term by years.
  • Ensure your loan allows extra payments without penalties.

2. Switch to a Lower-Interest Mortgage

Interest rates can vary significantly between lenders. Consider:

  • Comparing rates regularly to see if you could refinance.
  • Using a mortgage broker to find competitive deals.

3. Choose a Shorter Loan Term

A shorter loan term usually comes with lower interest rates. While your repayments may be higher:

  • You pay less interest overall.
  • You own your home sooner.

4. Make Weekly or Fortnightly Payments

Instead of paying monthly:

  • Weekly or fortnightly payments mean you make 26–52 smaller payments per year instead of 12.
  • Extra payments go toward reducing your principal, cutting interest faster.

5. Round Up Your Repayments

Rounding up your repayments is simple but effective:

  • For example, if your weekly repayment is $685, round it up to $700.
  • That extra $15/week goes directly toward your principal.

6. Use an Offset Account

Some mortgages allow an offset account linked to your loan:

  • Your savings reduce the interest you pay on your mortgage.
  • For example, $10,000 in an offset account can reduce your interest charges as if your loan is $10,000 smaller.

7. Avoid Interest-Only Loans for Long-Term

Interest-only loans may seem attractive at first, but:

  • You’re only paying interest, not reducing the principal.
  • Switching to principal-and-interest repayments sooner saves you money in the long run.

Bonus Tip: Track Your Progress

Use online mortgage calculators to see how much you could save by:

  • Making extra repayments
  • Switching repayment frequency
  • Refinancing to a lower rate

Monitoring your mortgage regularly helps you make informed decisions and motivates you to stick to your plan.


Final Thought:
Even small changes can save Kiwis thousands in interest over the life of a mortgage. Start with one strategy and build from there—your future self will thank you!
