Should you Refix or Refinance your Mortgage?

Making Smart Moves in a Changing Rate Market

As interest rates continue to shift across New Zealand, many homeowners are asking: Should I refix my mortgage, or is it time to refinance?

While the two options sound similar, the right move can make a big difference to your long-term financial position. Here's what each one means — and how to decide which is right for you.

What Does It Mean to Refix Your Mortgage?

Refixing means locking in a new fixed-rate term with your existing lender once your current fixed period ends. It’s a straightforward way to keep things rolling without changing banks.

You might consider refixing if:

  • You're happy with your current bank
  • You want a hassle-free option
  • You're not expecting significantly better rates elsewhere
  • You're eligible to get a cashback payment from the bank to stay with them

Refixing is often a fast and cost-free process, but it still pays to check the market. Even a small rate difference could save you thousands over the life of your loan.

What Is Refinancing?

Refinancing involves moving your mortgage to a new lender. This gives you the opportunity to find a sharper rate, rework your loan structure, or even release equity for renovations or investments.

Refinancing might be the right move if you:

  • Want to secure a better rate or cashback deal
  • Need more flexible loan options
  • Want to restructure your loan to suit your goals
  • Are planning renovations, investing, or consolidating debt

There may be costs involved — like break fees, legal costs, or new setup fees — but these can often be offset by lender incentives or long-term savings.

Refix or Refinance — Which Is Better for You?

Here are a few key things to consider when weighing up your options:

📈 Interest Rate Trends

If rates are likely to rise, locking in sooner may give you peace of mind. If they’re falling, you might consider going floating or fixing for a shorter term.

🎯 Your Financial Goals

Are you aiming to reduce your payments, pay your loan off faster, or free up funds for a project? Your goals will guide the best structure.

💰 Cashback Offers & Sweeteners

Banks often offer cashback to win new business — but don’t get swayed by short-term cash if the long-term rate isn’t competitive.

🔧 Loan Structure

Refinancing opens the door to new features like offset accounts, interest-only options, or splitting your loan into multiple portions.
