Switching Lenders: What to Consider Before You Move

Many New Zealand homeowners stay with the same lender for the life of their mortgage simply out of habit or inertia. In reality, switching lenders at the right time can result in a better rate, a more suitable loan structure, or improved service. At Chaperone, we regularly help borrowers assess whether switching is worth it, and the answer depends on several factors that are worth understanding before you start the process.

Why Borrowers Switch Lenders

The most common reason is a more competitive interest rate. Even a difference of 0.25% to 0.5% on a large mortgage represents meaningful money over time, and lenders will sometimes offer sharper pricing to attract new customers than they offer existing ones. Some borrowers switch because their financial situation has changed and their current lender's policies no longer suit them, whether that is due to being self-employed, investing in property, or needing a more flexible loan structure.

Others switch because they have had a poor service experience, or because they want access to features their current lender does not offer, such as a revolving credit facility, a more competitive offset arrangement, or better digital tools for managing their loan.

The Real Costs of Switching

Switching lenders is not costless, and it is important to go in with clear numbers. The main costs typically include:

• Break fees if you are exiting a fixed-rate period early. These can be substantial if interest rates have moved significantly since you fixed, and the formula used to calculate them varies between lenders.
• Discharge fees from your existing lender, which cover the administrative cost of releasing the mortgage security.
• Legal fees for the new mortgage documentation. Most lenders use a solicitor to register the new mortgage, and this cost is typically passed on to the borrower.
• A registered valuation may be required by the new lender, particularly if the property has not been formally valued recently.

Some lenders offer cash contributions to help cover the cost of switching. These are worth factoring into your comparison, but it is important to understand the conditions attached, as they often require you to stay with the new lender for a specified period or repay a portion of the contribution if you leave early.

Your Financial Position Will Be Reassessed

A new lender will treat your application as a fresh one. They will assess your income, expenses, credit history, and the property value from scratch. If your circumstances have changed since you originally took out your mortgage, such as a reduction in income, additional debt, or a drop in the property value relative to what you owe, you may find it harder to qualify than you expect.

This is particularly relevant under the Credit Contracts and Consumer Finance Act (CCCFA), which requires lenders to conduct thorough affordability assessments. A mortgage adviser can help you understand how a new lender is likely to view your application before you commit to the process.

Timing Matters

The cleanest time to switch is when your fixed-rate term expires. At this point, there are no break fees, and you are free to move without penalty. If you have multiple fixed tranches rolling over at different times, it is worth planning ahead so you can switch either all at once or in a structured way that avoids unnecessary costs.

Switching mid-fixed-term can still make financial sense if the rate difference is large enough to offset the break fee, but the calculation needs to be done carefully. Getting this analysis wrong is a common mistake that can turn a seemingly attractive switch into an expensive one.

What a Mortgage Adviser Can Do

Comparing mortgage offers across multiple lenders is time-consuming and requires a good understanding of the full cost picture. A mortgage adviser can access offerings from a range of lenders, model the true cost of switching versus staying, and manage the application process on your behalf. They can also negotiate on your behalf, which sometimes produces better outcomes than going directly to a lender as a retail customer.

At Chaperone, we think switching lenders should be a deliberate, well-informed decision rather than a reactive one. Taking the time to run the numbers properly ensures that the move actually works in your financial favour.
