The Most Common Mortgage Myths in New Zealand—Debunked for 2025

Are you planning to buy your first home in New Zealand but feeling overwhelmed by conflicting mortgage advice? You’re not alone. The Most Common Mortgage Myths in New Zealand continue to mislead potential homebuyers, creating unnecessary barriers and poor financial decisions. With interest rates fluctuating and lending criteria evolving in 2025, it’s crucial to separate fact from fiction in the New Zealand property market.

This comprehensive guide debunks the most persistent mortgage myths that could be costing you thousands of dollars or preventing you from achieving homeownership altogether. Let’s explore the reality behind these misconceptions and empower you with accurate, up-to-date information for 2025.

Myth 1: You Must Have a 20% Deposit to Get a Mortgage in New Zealand

The Reality: This is perhaps the most damaging myth preventing first-time buyers from entering the property market. While a 20% deposit can help you avoid Lenders Mortgage Insurance (LMI) and secure better interest rates, it’s absolutely not a strict requirement for obtaining a home loan in New Zealand.

Many New Zealand lenders offer mortgages with deposits as low as 10% or even 5% in certain circumstances. The government’s First Home Loan scheme, administered by Kāinga Ora, allows eligible buyers to purchase with deposits as low as 5% for existing homes and 10% for new builds[1]. Additionally, some banks have specific low-deposit products designed for first-time buyers.

However, it’s important to understand the trade-offs. Smaller deposits typically result in:

• Higher interest rates
• Lenders Mortgage Insurance costs
• More stringent application requirements
• Limited property options

Myth 2: Fixed-Rate Mortgages Are Always Better Than Floating Rates

The Reality: There’s no one-size-fits-all answer when it comes to choosing between fixed and floating mortgage rates. Your decision should be based on your individual financial situation, risk tolerance, and market conditions in 2025.

Fixed-rate mortgages provide certainty and stability, protecting you from interest rate increases during the fixed term. This makes budgeting easier and provides peace of mind. However, floating rates offer more flexibility, allowing you to make extra repayments without penalty and potentially benefit from rate decreases.

In New Zealand’s current market context for 2025, many experts suggest a split approach, where you fix a portion of your mortgage and keep some on floating rates. This strategy allows you to benefit from both stability and flexibility while minimizing risk.

Myth 3: Bad Credit Automatically Disqualifies You From Getting a Mortgage

The Reality: While good credit certainly helps secure better mortgage terms, having less-than-perfect credit doesn’t automatically eliminate your chances of homeownership. Many New Zealand lenders offer specialized products for borrowers with credit challenges.

With approximately 25% of New Zealanders having credit scores that make traditional bank lending difficult[3], the mortgage industry has adapted to serve this significant market segment. Alternative lenders, credit unions, and specialist mortgage providers often have more flexible lending criteria.

If you have bad credit, you can expect:

• Higher interest rates to offset perceived risk
• Requirements for larger deposits
• More thorough income and expense verification
• Potential guarantor requirements

Working with an experienced mortgage adviser who understands the lending landscape can help you find suitable options and improve your chances of approval.

Myth 4: You Should Always Choose the Mortgage with the Lowest Interest Rate

The Reality: While interest rates are undoubtedly important, focusing solely on the lowest rate can be a costly mistake. The true cost of your mortgage depends on multiple factors that extend far beyond the advertised rate.

When evaluating mortgage options in 2025, consider these crucial factors:

Application and Ongoing Fees
Some lenders offer low rates but charge high establishment fees, annual fees, or exit fees that can significantly increase your total costs.

Loan Features and Flexibility
Features like offset accounts, redraw facilities, and the ability to make extra repayments can save you thousands over the life of your loan, even if the interest rate is slightly higher.

Customer Service and Support
Consider the lender’s reputation for customer service, especially during financial hardship or when you need to restructure your loan.

Myth 5: You Should Pay Off Your Mortgage as Quickly as Possible

The Reality: While paying off your mortgage early can save interest, it’s not always the optimal financial strategy for everyone. The decision depends on your overall financial picture, investment opportunities, and personal circumstances.

Consider these factors before aggressively paying down your mortgage:

Opportunity Cost
If you can earn higher returns through investments than your mortgage interest rate, it may be more beneficial to invest excess funds rather than pay down your mortgage.

Tax Implications
For property investors in New Zealand, mortgage interest can be tax-deductible, making the effective cost of borrowing lower than the stated interest rate.

Liquidity and Emergency Funds
Maintaining accessible emergency funds and investment liquidity is often more important than rapidly reducing mortgage debt.

Myth 6: Pre-approval Guarantees You’ll Get the Mortgage

The Reality: Pre-approval is a conditional commitment based on the information you’ve provided and your financial circumstances at the time of application. It’s not a guarantee of final loan approval.

Pre-approval can be withdrawn or modified if:

• Your financial situation changes
• The property doesn’t meet lending criteria
• Additional information comes to light during final assessment
• Market conditions change significantly

Use pre-approval as a guide to your borrowing capacity, but understand it’s subject to final verification and property valuation.

Myth 7: Online Mortgage Calculators Are Completely Accurate

The Reality: While online mortgage calculators are useful tools for initial estimates, they can’t account for all the variables that affect your actual borrowing capacity and mortgage costs.

Calculators typically don’t consider:

• Your complete financial profile
• Individual lender criteria and policies
• Current market conditions and rate changes
• Additional costs like insurance and legal fees
• Your specific employment situation

Use calculators as starting points, but always consult with mortgage professionals for accurate, personalized advice.
