ANZ Mortgage Calculator NZ 2026: Estimate Your Home Loan Repayments
Buying a home is the biggest financial decision most Kiwis will ever make. Before you fall in love with a property, understanding your likely mortgage repayments is essential. ANZ is New Zealand's largest home lender, and their mortgage calculator is one of the most widely used tools for estimating repayments. This guide walks you through how to use it, what the numbers mean, and how to make sure you're borrowing within your means in 2026.
How the ANZ Mortgage Calculator Works
The ANZ mortgage calculator is available on their website and requires three key inputs: the loan amount, the interest rate, and the loan term. Once entered, it displays your estimated weekly, fortnightly, or monthly repayment. You can also toggle between principal and interest repayments and interest-only repayments, which is useful for investors.
The calculator uses standard amortisation formulas. In the early years of your mortgage, the majority of each repayment goes toward interest rather than reducing the principal. Over time, as the principal decreases, more of each payment chips away at the actual debt. ANZ's tool shows this breakdown clearly, which helps borrowers understand the long-term cost of their loan.
One useful feature is the ability to model extra repayments. If you can afford to pay an additional $50 or $100 per week, the calculator shows how many years you can shave off your mortgage and how much interest you save overall. For most borrowers, even small extra repayments make a significant difference over a 25 or 30 year term.
Current ANZ Home Loan Rates in 2026
ANZ offers both floating and fixed rate home loans. Fixed rates lock in your interest rate for a set term — typically six months, one year, two years, or five years — giving you certainty about repayments. Floating rates move with the Official Cash Rate (OCR) set by the Reserve Bank of New Zealand (RBNZ) and can change at any time.
As of early 2026, fixed rates have moderated following the RBNZ's easing cycle that began in 2024. One and two-year fixed rates are the most popular choice for Kiwi borrowers, offering a balance between rate certainty and flexibility to refix at lower rates if they continue falling. Always check ANZ's website directly for current rates, as these change frequently.
When using the mortgage calculator, it's worth modelling a rate slightly higher than current offers — perhaps 1% to 2% above — to stress test your budget. This ensures you can still afford repayments if rates rise when your fixed term expires, which is known as a rate shock scenario.
How Much Can You Borrow with ANZ?
ANZ uses the Credit Contracts and Consumer Finance Act (CCCFA) requirements to assess affordability. They look at your income, existing debts, living expenses, and dependants. The bank applies a test rate (higher than the advertised rate) to ensure you can service the loan even if rates increase.
As a rough guide, most borrowers can service a mortgage of approximately four to five times their gross annual income, though this varies significantly based on individual circumstances. The ANZ mortgage calculator helps you reverse-engineer this: enter your target repayment amount and it shows you the corresponding loan size.
The minimum deposit for owner-occupiers is typically 20%, though ANZ does offer some loans with a 10% deposit under the First Home Loan scheme backed by Kāinga Ora. Investors generally require a 35% deposit under RBNZ loan-to-value ratio (LVR) restrictions.

Fixed vs Floating: Which Is Right for You?
The choice between fixed and floating is one of the most common questions Kiwi home buyers face. Fixed rates give certainty — you know exactly what your repayments will be for the fixed term. This makes budgeting easier and protects you from rate rises. The downside is that if rates fall, you're locked in at a higher rate until refixing, and there can be break fees if you need to change your mortgage mid-term (for example, if you sell the property).
Floating rates move with the OCR and offer more flexibility. You can make lump sum repayments at any time without penalty, which is useful if you receive a bonus or inheritance. However, your repayments can increase at any time if the RBNZ raises the OCR.
Many Kiwis split their mortgage — fixing a portion for certainty while keeping a smaller portion floating for flexibility. ANZ offers split loan structures, and their calculator allows you to model different splits.
First Home Buyer Tips
If you're a first home buyer, there are additional schemes worth knowing about alongside the ANZ mortgage calculator. KiwiSaver first home withdrawal allows you to use your KiwiSaver savings (after at least three years of contributions) toward your deposit. The First Home Grant from Kāinga Ora provides up to $10,000 per person ($20,000 for couples) for eligible buyers of new builds, subject to income and property price caps.
It's also worth getting a mortgage pre-approval before house hunting. ANZ's pre-approval process assesses your borrowing capacity and gives you a conditional approval for a specific loan amount, typically valid for 60 to 90 days. This lets you bid at auction with confidence.
Using a mortgage broker is free for borrowers — the broker is paid by the lender — and can help you compare ANZ's rates and terms against other banks like BNZ, Westpac, ASB, and Kiwibank to make sure you're getting the best deal.
Refinancing and Refixing Your ANZ Mortgage
When your fixed rate term expires, you'll need to refix — choose a new fixed rate term — or move to the floating rate. This is an important decision point. ANZ will contact you before expiry with current rate options. However, you're not obligated to stay with ANZ; you can refinance to another lender if they're offering better rates.
Refinancing involves some costs: legal fees (typically $800 to $1,500), a potential cashback from the new lender (which often offsets these costs), and administrative time. If ANZ offers a cashback for new lending, this can sometimes be worth taking even if their rate isn't the absolute lowest.
Frequently Asked Questions
How accurate is the ANZ mortgage calculator?
The ANZ calculator provides a good estimate for budgeting purposes, but the actual repayment amount may differ slightly based on how ANZ structures your loan, the specific rate agreed at settlement, and whether any fees are capitalised into the loan. Always confirm exact figures with your ANZ home loan specialist before signing.
Can I use the ANZ calculator for investment property loans?
Yes, the same calculator applies to investment property loans. However, investment loans typically require a 35% deposit under RBNZ LVR restrictions, and interest rates may differ slightly from owner-occupier rates. Interest-only periods are also available for investors, which the calculator can model.
What is the maximum mortgage term ANZ offers?
ANZ offers mortgage terms of up to 30 years. Longer terms reduce monthly repayments but significantly increase total interest paid over the life of the loan. A 30-year term costs substantially more in interest than a 25-year term on the same loan amount.
Does ANZ charge break fees on fixed rate mortgages?
Yes, if you break a fixed rate mortgage early (for example, to sell the property or refinance), ANZ may charge a break fee. The fee is calculated based on the difference between your fixed rate and current wholesale rates for the remaining term. In a falling rate environment, break fees can be substantial.
What is a revolving credit facility and does ANZ offer one?
A revolving credit facility (also called a home equity line of credit) lets you use the equity in your home like an overdraft. ANZ offers this product, which can be useful for renovations or investments, but requires strong financial discipline as the debt can grow if not managed carefully.
Can I make extra repayments on a fixed ANZ mortgage?
ANZ typically allows extra repayments of up to $500 per year on fixed rate loans without penalty. Beyond that amount, you may incur break fees. On floating rate loans, extra repayments are unlimited and free, which is one advantage of the floating option.
How do I apply for pre-approval with ANZ?
You can apply for ANZ home loan pre-approval online, in branch, or through a mortgage broker. You'll need proof of income (payslips or tax returns for self-employed), bank statements, details of existing debts, and identification. ANZ typically provides a pre-approval decision within a few business days.
