Switching Banks: A Complete Guide to Refinancing Your Mortgage in NZ

Refinancing means moving your mortgage from one lender to another. The new lender pays out your existing loan, and you begin making payments to them instead. Beyond potential rate savings, refinancing can provide access to better loan features, cash contributions, and improved service.

While the benefits can be significant, refinancing involves costs and effort. Understanding the full process helps you evaluate whether switching makes sense for your situation and prepare for what is involved.

When to Consider Switching

Several triggers make refinancing worth exploring. The most common is simply discovering you are paying more than current market rates. If your fixed rate is expiring and your bank's refix offer is uncompetitive, shopping around often reveals better options elsewhere.

Life changes may also prompt a review. Income increases might allow you to access better rates based on your improved position. Relationship changes, whether new partners combining finances or separations requiring loan restructuring, often involve refinancing considerations.

The Refinancing Process

Refinancing follows a similar process to obtaining your original mortgage, though often faster since you already own the property and have an established payment history.

Step 1: Compare Your Options

Before committing to switch, understand what is available. Comparing loan offers involves more than headline rates. Consider cash contributions, loan features, fees, and service quality. A mortgage adviser can compare across multiple lenders efficiently, often accessing rates not publicly advertised.

Step 2: Application and Approval

Apply to your chosen new lender with financial documentation similar to your original loan application: income evidence, bank statements, identification, and property details. The lender assesses your application against their criteria and orders a property valuation if required.

Approval timelines vary from a few days to several weeks depending on lender workloads, your circumstances' complexity, and how quickly you provide requested information. Having documentation ready before applying accelerates the process.

Step 3: Settlement

Once approved, your new lender's solicitor coordinates with your existing lender to arrange the transfer. On settlement day, the new lender pays out your existing mortgage and registers their mortgage against your property. Your old bank removes their mortgage from the title.

You typically have little to do during settlement. Your solicitor handles the legal work, and the lenders manage the money transfer between themselves. You simply start making payments to your new lender from the agreed date.

Costs of Refinancing

Refinancing involves several costs that must be weighed against potential savings. Understanding these costs helps you calculate whether switching makes financial sense.

Legal Fees

Solicitor fees for the property title transfer typically run $800 to $1,500. Some lenders offer to cover legal costs as part of their cash contribution to attract your business. Even without coverage, legal fees are usually recovered quickly through rate savings.

Break Fees

If you are breaking a fixed rate to refinance, your existing lender may charge a break fee. These fees compensate the lender for lost interest and can range from negligible to substantial depending on rate movements since you fixed. Get an exact quote from your current lender before committing to switch.

Break fees are lowest when market rates have risen since you fixed, and highest when rates have fallen. In some cases, breaking your fixed rate is worthwhile despite the fee if savings from the new rate are sufficient.

Valuation Fees

The new lender may require a property valuation, costing $400 to $700 for a full valuation. Some lenders waive valuation requirements for lower LVR borrowers or accept desktop valuations at lower cost. Valuation requirements vary, so ask upfront.

What Happens to Your Old Bank

When you refinance away, your existing bank receives notice that their mortgage is being paid out. They prepare a final statement showing the exact payout amount including any accrued interest and fees. After settlement, they provide discharge documents to clear their interest from your property title.

There is no penalty for leaving a bank beyond any applicable break fees. You do not need to give notice or explain your reasons. Banks compete for business and losing customers to competitors is part of normal market dynamics.

Potential Complications

Most refinancing proceeds smoothly, but occasionally complications arise. Understanding potential issues helps you address them proactively.

Changed Circumstances

If your income has decreased, you have taken on additional debt, or other aspects of your financial position have weakened since your original loan, the new lender may decline your application or offer different terms. Assess your current circumstances honestly before applying.

Property Value Issues

If your property value has decreased, your equity position may be weaker than expected. The new lender's valuation might come in lower than you anticipated, affecting the LVR and potentially the rate offered or approval itself.

Title Issues

Occasionally, title searches reveal issues like unregistered easements, caveats, or other encumbrances that complicate the transfer. These are rare but can delay settlement while resolved. A lawyer's title review early in the process identifies any concerns.

Working with a Mortgage Adviser

A mortgage adviser can significantly simplify the refinancing process. They compare options across multiple lenders, handle much of the application paperwork, liaise with lenders on your behalf, and often access rates and deals not publicly available.

Adviser services are typically free to borrowers, as lenders pay commission on successful refinancing. This makes their expertise essentially a no-cost resource for navigating your options and managing the process efficiently.

Refinancing is a normal part of proactive mortgage management. The best borrowers review their position regularly and switch when doing so serves their interests. Bank loyalty rarely rewards you as much as shopping the market and ensuring you have the best available deal.
