How To Choose The Best Bank For Your Home Loan

Which is the best bank in NZ for home loans?

It depends on you, and on timing. Your income, your deposit, your plans and how you like to handle money all change the answer. Bank policies and specials move around too, so the best bank this year might not be the best one next year. When I compare lenders for someone, this is what I look at:

• Rates that stay competitive across the fixed terms, not one headline special.
• Flexibility on fixed loans: can you pay extra, drop back to the minimum if you need to, and get at money you’ve paid ahead?
• Useful floating options, such as a revolving credit or an offset facility.
• Lending policy that fits you. Banks treat income, deposits and debts differently, and that can change how much you can borrow.

The lowest advertised rate is only one part of it. The best home loan gives you control and flexibility, and helps you become mortgage-free sooner.

Three common reasons people pick the wrong bank

All three sound sensible, and the banks are happy for you to think they’re what matters. In my experience they aren’t.

1. It’s the bank you already use

Your own bank already has your records and has you set up in its systems, so applying there feels quick and easy. But how do you know it has the best option for you? Most people don’t. If you don’t know what makes a good home loan, it’s easy to assume they’re all the same. At best, the person at the bank will tell you about the features of their own loan. It may sound good, but you’ve got nothing to compare it with.

2. It’s the first bank to approve you

When you’re buying, the real estate agent may be pushing you to get finance sorted fast. You’ve fallen for the house, and the loan becomes an afterthought. That’s especially true for first home buyers and anyone with a smaller deposit, and most people go with whichever bank says yes first. In my experience, lenders with the better loan products are often busier, so they can be slower. Where you can, apply for the loan you actually want first and be ready to wait a little longer for the answer.

3. It’s the bank advertising the lowest rate

Banks advertise specials to win new business. The special is usually on one fixed term, which locks you in for that period, and the bank knows most people will stay and refix without looking hard at the new rate. No bank has the lowest rate all the time. You’ll probably have this loan for a long time, so a bank that’s competitive across its fixed terms year after year matters more than one sharp special.

Warning signs you didn’t get much advice

• You took the loan with your existing bank without comparing others.
• You went direct to the bank, and the banker seemed nice to deal with.
• Your whole mortgage sits in one fixed loan.
• You’re paying the minimum repayment.
• Nobody talked to you about offset or revolving credit.

Why don’t banks bring this up? Because features that help you pay the loan off faster mean the bank earns less interest from you.

What makes the best home loan in NZ

I’m talking about the loan on the home you live in, and I’m assuming you want to pay it off as fast as you sensibly can while keeping room to adjust when life changes. Investment property, business lending, bridging finance and specialist lending can call for a different approach. For your own home, this is what I look for:

1. Your mortgage split across more than one fixed loan. Fixed rates give you certainty and make budgeting easier. Splitting across two or three fixed loans gives you more choices each time one comes up for refixing.
2. A small revolving credit or offset. The limit doesn’t need to be big. It lets you adjust repayments, build up lump sums and keep some money in reserve. It’s handy when you can see a change coming, like starting a family, going back to study or changing jobs.
3. A decent allowance for extra repayments on fixed loans. Most banks let you pay a bit extra while you’re fixed, but the limits vary, and paying more than the allowance can trigger a prepayment (break) cost. A limit that applies to each loan split works better than one limit across the whole mortgage, because every split gives you another chance to pay extra.
4. Paying extra without locking in a higher minimum. In my experience, when you ask some banks to increase your repayments they shorten the loan term to match, so the higher amount becomes your new required repayment. That sounds fine until rates rise or your income drops. Ask how an increase is set up before you make it.
5. The ability to drop back to the minimum, and to get money back if you need it. If you know you can reduce your repayments again, you’re far more likely to pay extra in the first place. Westpac’s Choices Fixed, for example, lets you increase repayments by up to 20% above the minimum and go back down when you need to (as at September 2026). Some lenders also let you redraw what you’ve paid ahead, and money paid into a revolving credit or offset can always be drawn back out.

Fixed loans: certainty, with less flexibility

Fixing gives you a set rate and a set repayment for the term you choose. In New Zealand, fixed rates have usually been lower than floating rates, and that’s still the case. In September 2026, for example, Westpac’s standard floating rate was 6.14% while the lowest one-year fixed rates were just under 5%. That’s why most Kiwis put most of their lending on fixed. The trade-off is flexibility. Once you’ve fixed, it’s harder to pay extra, reduce repayments or make changes without a cost. Floating gives you flexibility, with less certainty and usually a higher rate.

Offset accounts: make your savings work against your loan

Most people have money spread across a few accounts earning very little, and that interest is taxed. With an offset home loan, the balances in linked accounts are offset against the loan, so you only pay interest on the difference. Say you owe $500,000 and have $20,000 across your savings and everyday accounts. You’d pay interest on $480,000, and you can still get at your money whenever you like. Only a few lenders offer offset. As at September 2026, among the main banks that’s BNZ (TotalMoney), Kiwibank and Westpac. Offset works on the floating part of the loan, and banks without an offset product aren’t going to bring it up.

Revolving credit: works if you’re disciplined

A revolving credit works like a large overdraft secured against your home. Your income goes into it, and every dollar sitting there reduces the balance you’re charged interest on. Interest is worked out daily, so even the few days your pay sits there before the bills go out help. The catch is that it’s easy to spend again what you’ve already paid off. If you budget well, it can be one of the fastest ways to bring your mortgage down. If you don’t, it can hold you back.

Which mix suits you?

• Fixed suits you if you want steady repayments and like knowing exactly where you stand.
• Offset suits you if you usually keep a reasonable balance in savings or everyday accounts and want to keep access to it.
• Revolving credit suits you if you’re good with money and want every spare dollar working on the loan.

Often the answer is a mix: most of the loan fixed for stability, plus an offset or revolving credit for flexibility. Not every bank offers every option, so the structure you want can decide which bank is best for you.

Why paying it off faster matters more than a small rate difference

Here’s an illustration. On a $600,000 loan over 30 years at 5.50%, weekly repayments are about $786, and you’d pay the bank about $1.23 million in total. Add $75 a week and the loan is repaid about five and a half years sooner, saving roughly $137,000 in interest. That assumes the rate stays the same for the whole 30 years, which it won’t, so treat it as an illustration only. Try your own numbers in the mortgage calculator.

A loan that makes it easy to pay extra, and safe to ease back when you need to, is usually worth more over the years than a slightly lower rate on a rigid loan.

Best bank for home loans in NZ: how the main lenders compare

People searching for the best bank for a home loan usually want a ranked list. I can’t give you an honest one, because rates and policies change often and the “best” lender is the one that fits your situation. What I can do is describe how each group of lenders tends to suit different borrowers. Check current rates and policy with each lender before you decide.

• ANZ and ASB: two of the big four, with broad product ranges and wide networks. Both are worth including whenever you compare, particularly if you want a full banking relationship. Check how each treats your income type and deposit.
• BNZ: offers an offset facility (TotalMoney) and is one of the lenders that lends to 5% deposit buyers.
• Westpac: offers an offset facility and, on its Choices Fixed loan, lets you increase repayments and go back to the minimum, as covered above.
• Kiwibank: NZ-owned, with an offset facility. Worth a look if you want a New Zealand-owned lender.
• Other banks and non-banks: SBS, Co-op Bank and Unity, plus non-bank lenders such as Avanti Finance and Pepper Money, can suit self-employed borrowers, smaller deposits or past credit issues. Non-bank lending is often a stepping stone that you later refinance back to a bank, usually at a higher rate while you’re there.

The best home loan for you is a combination: the right lender for your income and deposit, and a loan structure that lets you pay it off faster. Two people with the same lender can end up with very different outcomes depending on how the loan is set up, which is why I cover getting the best from your home loan separately.

A mortgage broker versus going direct to a bank is the other big decision. A bank can only offer you its own products. An adviser can compare across the panel before anything is lodged.

The best bank for home loans also depends on your situation

Loan features are only half of it. Every bank assesses income, debts and deposits differently, so the best bank for you is also the one whose policy fits where you are right now.

• Buying your first home? See my first home buyers guide. Several banks offer first home buyers a cash contribution, usually with a minimum loan size and a clawback if you leave within a few years. It’s worth having, but it’s only one part of the decision.
• Deposit under 20%? Only some lenders will suit. See low deposit home loans.
• Self-employed? Lenders treat your income very differently. See home loans for self-employed.
• Past credit issues? A main bank may not be the right fit yet. See bad credit options.
• Buying an investment property? See property investment loans.
• Not sure how much you can borrow? The bank you pick can change the answer. See how much can I borrow in NZ.

Already have a home loan? Review it regularly

Your mortgage is probably one of the biggest financial commitments you’ll ever have, yet plenty of people spend more time researching a new phone. After a few years, most people just refix with whatever the bank offers. A regular review can find a better rate or structure, check you’re paying the loan down efficiently and stop you paying costs you don’t need to.

When your fixed terms come up, a good adviser should also push your bank to match better rates available elsewhere. I’m happy to do that review for you, whether or not I arranged your loan. If moving banks makes sense, see refinancing your mortgage.
