Mortgage Refinancing is the complete process of replacing your current home loan with a new one. This involves taking out a new mortgage—often with a different lender or bank—to fully repay your old one.
Unlike simple refixing—where you often only update your interest rate with your existing bank—refinancing is a more comprehensive financial reset often designed to help you pursue a more suitable overall deal (rates and/or cashback) and loan structure.
The primary goals of a strategic refinance generally are to:
Refinancing is a strategic decision that goes far beyond simply accepting a new rate from your current bank. It is sometimes the best way to ensure your mortgage truly serves your current and future financial goals.
A good time to consider a full refinance (switching lenders) is when your existing fixed term is expiring.
You may want to consider initiating a refinance review when market conditions or competitor offers suggest there could be financial advantages in switching.
If your property value has increased and your current lender is unable to offer the additional funds you need — whether for renovations, investment property purchases, or other goals — another lender may reassess your situation and provide alternative options.
Refinancing may also allow you to consolidate higher interest debts, such as credit cards or personal loans, into your home loan, which can result in a lower combined interest rate depending on your circumstances.
In addition, some lenders offer features that may better suit your financial plans, such as:
These features vary between lenders, and eligibility depends on your financial position and the lender’s criteria.
Refinancing can be a way to streamline your lending costs by removing certain recurring charges and reducing upfront expenses—depending on your circumstances.
Refinancing can give you access to lending products that your current bank may not offer. This can include “Green Loans,” which some lenders provide for eligible energy efficient upgrades — such as solar panels, heating, or insulation — or for the purchase of hybrid or electric vehicles. Depending on the lender and offer, these products may feature reduced rate or low interest financing for amounts that can extend up to certain lender defined limits.
While refinancing can save you money, there are some typical costs to consider:
| Cost Type | Why it Occurs | Key Tip |
|---|---|---|
| Break Fees | Charged if you exit a fixed loan term early with your current lender. | You should consider whether the switch is financially worthwhile, and we can help calculate any applicable fees to support that assessment. |
| Legal | Required to discharge and register the new mortgage through a lawyer. | Many NZ banks offer cashback incentives that may help offset some or all of your refinancing costs, depending on eligibility and lender criteria. |
| Valuation Cost | New lender may require an updated, independent Registered Valuation of your property to confirm its market worth and LVR | Many NZ banks offer cashback incentives that may help offset some or all of your refinancing costs, depending on eligibility and lender criteria. |
| Discharge Fee | A small charge applied by your current bank to release the loan. | You should consider how this factors into your overall savings assessment. |
At Global Finance, we’ve helped many New Zealanders save in interest and fees. Here’s how we make refinancing easy:
We compare a wide range of lenders on your behalf — including NZ banks and non bank lenders — reviewing interest rates, cashback offers, and available promotions. This gives you a clearer view of the options available, helping you consider which refinancing solution may be the most competitive for your situation.
Whether you're looking for lower repayments, aiming to pay down your mortgage sooner, wanting to access equity, or considering debt consolidation, we help you explore loan structure options that may align with your lifestyle and long term financial plans.
Refinancing is more than switching banks — it’s an opportunity to reassess how your home loan is structured. We work with you to identify loan structure options that may support your cash flow needs and long term goals. This can include tools such as our Mortgage Genius Plan®, which is designed to help you explore ways to better manage your repayments and potentially reduce interest costs over the life of your loan.
Refinancing can feel complex, but we guide you through every step. Our advisers prepare and submit your application, review lender offers, negotiate on your behalf, and may coordinate with lawyers, valuers, and the new lender for account setup. Our goal is to make the process as smooth and stress free as possible.
Our support doesn’t end at settlement. We can schedule regular reviews to reassess your mortgage against market changes and lender offers. This helps ensure you continue to have suitable options over time — whether that means refixing with your current bank or considering another strategic refinancing opportunity as your needs evolve.
A good time is usually when your fixed term is ending, or when the savings from a lower rate outweigh any break costs. You can still refinance if you have still time left on your fixed rate, but your bank may charge a break fee. Sometimes the savings from a lower rate and the cash incentive from the new bank still outweigh the cost.
Yes, refinancing is treated as a new loan application. Lenders will assess your financial situation, credit history, and may require a property valuation. Typically, you'll need to provide proof of income (e.g., payslips, tax returns), recent bank statements, current mortgage statement, identification documents, property valuation (if required by the new lender)
As a guideline, about 2–4 weeks, but this can depend on the lender and whether a valuation is needed.
Not usually, but it depends on the circumstances.
Yes. People consider refinancing to combine higher interest debts — such as credit cards or personal loans — into their home loan to improve repayment affordability, or to access equity for goals like renovations, a vehicle purchase, a second property, or education related expenses.
