Which New Zealand home loan lenders should you consider in 2026?

With your fixed-rate home loan expiring in two months, you have a good opportunity to review your options. My recommendation is to compare your current bank against at least two competing lenders before you refix or refinance.

You don't necessarily need to switch banks to get a better deal. Your existing bank may offer a competitive rate to retain your business, while another lender might provide a better combination of interest rates, cashback and loan flexibility.

In New Zealand, I'd start by comparing ANZ, ASB, BNZ, Westpac, Kiwibank and a non-bank lender such as SBS Bank or TSB, depending on your circumstances and the deals available.

The best option will depend on your mortgage balance, equity, income, whether you want to fix or float, and how much flexibility you need.

1. My recommended lenders to compare

I'd shortlist these lenders, starting with the ones that have a clear reason to be on your comparison list.

1. Kiwibank — my first stop for competitive shorter-term fixed rates

Why I'd consider it: Kiwibank was offering the lowest advertised one-year fixed rate among the major banks as of 9 October 2026, according to Opes Partners' rate comparison. It was also competitive on six-month fixed rates. These are advertised rates, not a guarantee of what you'll personally be offered. opespartners.co.nz

Kiwibank is worth investigating if:

• You want to fix for one year rather than commit to a longer term.
• You have at least 20% equity and may qualify for its special rates.
• You're willing to move your mortgage to another bank if the overall deal is better.

My verdict: Make Kiwibank one of your first calls if a one-year fixed term appeals to you.

2. Westpac — my first stop for longer-term fixed rates

Why I'd consider it: Westpac reported that it had the lowest fixed rates among the five biggest banks on three- to five-year terms in September 2026. Opes Partners' comparison on 9 October also identified Westpac as having the lowest advertised three- and four-year rates among the major banks. westpac.co.nz, opespartners.co.nz

Westpac is worth investigating if:

• You prefer the certainty of a longer fixed term.
• You want predictable mortgage repayments for several years.
• You're comparing longer-term rates rather than focusing exclusively on the cheapest one-year offer.

The downside is that fixing for longer reduces your flexibility if you want to sell your home, repay a large amount or restructure your mortgage before the term ends.

My verdict: Put Westpac near the top of your list if payment certainty is your priority.

Website: Westpac home loans

3. BNZ — worth checking for longer-term rates and refinancing options

BNZ is another strong candidate for your comparison.

Its advertised five-year fixed rate was among the lowest of the major banks in the 9 October comparison. BNZ also explains the refinancing process clearly, including the potential costs of changing banks and the option to lock in a rate ahead of your existing fixed term ending. opespartners.co.nz, bnz.co.nz

BNZ is worth investigating if:

• You're considering fixing for three to five years.
• You want to compare a new-bank offer against your existing lender.
• You'd like to review your loan structure rather than simply renew the same arrangement.

My verdict: Include BNZ, particularly if you're considering a longer fixed term.

Website: BNZ home loans

4. ASB — a useful competitor for your existing bank

I'd include ASB in your comparison even if you don't currently bank with them.

ASB publishes its home loan interest rates and fees, including fixed and variable options. It also has an established process for customers considering switching their mortgage from another bank. asb.co.nz, asb.co.nz

ASB is worth considering if:

• Its actual offer is competitive with Kiwibank and Westpac.
• You want to compare fixed and variable loan structures.
• It offers a cash contribution that improves the overall value of refinancing.

My verdict: Keep ASB on your shortlist, but choose it based on the offer you receive rather than the brand.

Website: ASB home loans and interest rates

5. ANZ — worth checking for a retention deal

ANZ belongs in your comparison, especially if you already bank with them.

If ANZ is your current lender, ask what rate it can offer you to retain your mortgage. If it's not your current lender, request a competing quote.

The key is to compare ANZ's actual offer with the other banks' offers for the same fixed term and similar loan conditions.

My verdict: Don't overlook ANZ, but don't assume that staying with your existing bank is automatically the best deal.

Website: ANZ home loans

6. TSB or SBS Bank — alternative lenders worth a quote

I'd also consider TSB and SBS Bank if you want a wider comparison beyond the biggest banks.

They may be worth including if their rates, fees and lending terms suit your circumstances. However, I wouldn't assume either will beat the major banks: compare the actual offers available to you.

These lenders are particularly useful to investigate if you're willing to consider alternatives to the big-bank options.

Websites: TSB home loans and SBS Bank.

2. What are the best rates right now?

The latest comparison I found, dated 9 October 2026, identified these lowest advertised fixed rates among New Zealand's six major banks. These are market benchmarks, not personalised quotes. opespartners.co.nz

Fixed term	Lowest advertised rate	Lender identified in comparison
6 months	4.75%	Kiwibank and Westpac
1 year	4.95%	Kiwibank
2 years	5.39%	Kiwibank
3 years	5.39%	Westpac
4 years	5.39%	Westpac
5 years	5.49%	BNZ and Westpac

Important: These are advertised rates from a third-party comparison, not confirmed offers for your particular mortgage. Rates can change, and eligibility requirements may apply. Kiwibank, for example, distinguishes between special fixed rates for borrowers with at least 20% equity and standard rates for those with less. kiwibank.co.nz

Because your current rate expires in two months, I'd use these figures as a starting point rather than deciding to switch today. Ask each shortlisted lender for its current rate and whether you can secure that rate for your rollover date.

3. Should you stay with your current bank or switch?

This is where I would focus most of your attention.

A competing bank might advertise a lower interest rate and offer a cash contribution for moving your mortgage. But switching can involve legal fees, application costs and conditions attached to the cash contribution.

BNZ specifically identifies legal costs, possible valuation fees and cashback clawbacks as costs to investigate when refinancing. bnz.co.nz

Here's how I'd approach the decision.

Factor	Stay with your bank	Switch banks
Interest rate	Ask for a retention discount	Compare competing offers
Cash contribution	You might receive a retention incentive	A new bank may offer a cash contribution
Legal fees	Usually no new refinancing costs	Legal costs may apply
Administration	Generally simpler	Requires a new application and paperwork
Loan flexibility	You can review your existing structure	You can compare different loan structures
Approval	Usually simpler to renew an existing loan	New lending approval is required

A practical example

Suppose your outstanding mortgage is $600,000.

If another bank offers an interest rate that's 0.20 percentage points lower, the approximate initial interest saving would be:

• $1,200 per year.
• $3,600 over three years, assuming the rate difference remains constant and ignoring changes in the outstanding balance.

If switching costs you $2,000 in legal fees and other expenses, that leaves only around $1,600 in savings over three years, before considering any cash contribution.

This is why I wouldn't switch banks for a tiny interest-rate difference unless there were other meaningful benefits.

My rule of thumb: Ask your current bank to match the best competing offer first. If it won't, compare the net benefit of switching after all costs and incentives.

4. What should you do with your mortgage when the fixed rate expires?

The best lender also depends on how you want to structure your mortgage.

Option A: Fix for one year

Consider this if you want relatively short-term certainty without committing to a longer period.

Advantages:

• Your repayments are predictable during the fixed term.
• You can review your rate again in a year.
• You're not committed to a multiyear fixed term.

The trade-off is that you'll face whatever rates are available when you next refix.

Option B: Fix for two or three years

Consider this if you prefer a balance between repayment certainty and flexibility.

You avoid having to renegotiate your entire mortgage every year, although you'll have less flexibility to make major changes during the fixed term.

Compare Kiwibank and Westpac in particular, alongside your existing bank.

Option C: Split your mortgage across different fixed terms

This is worth considering if your mortgage is relatively large.

For example, if you have a $600,000 mortgage, you might split it into:

• $300,000 fixed for one year.
• $300,000 fixed for two years.

This staggers your refixing dates rather than exposing the entire mortgage to interest rates available on a single date.

It doesn't guarantee a lower interest cost, but it can spread the risk of having to refix the entire loan when rates are unfavourable.

You could also keep a portion floating or in an offset arrangement if you have savings or expect to make substantial extra repayments. However, variable rates can be considerably higher than fixed rates, so compare the cost carefully.

5. Your two-month action plan

With your fixed rate ending in December 2026, I'd do the following.

Now:

• Ask your existing bank for its best available rates across one-, two- and three-year terms.
• Request a breakdown of any cash contribution or retention offer.
• Check your remaining mortgage balance and current equity.

Over the next two to three weeks:

• Obtain quotes from Kiwibank, Westpac and BNZ.
• Compare at least one alternative, such as ASB, if you want a broader comparison.
• Compare the total financial benefit of switching, including legal costs and any cash contribution conditions.

Before your fixed rate expires:

• Negotiate with your current bank using the strongest competing offer.
• Decide which fixed term suits your financial circumstances.
• Confirm the rate, start date and any conditions in writing.

Ask your bank whether you can lock in a rate before your current fixed term expires. BNZ, for example, says customers can lock in a new rate up to 60 days before their mortgage rolls over, although conditions and charges can apply. bnz.co.nz

You have time to compare offers, but I wouldn't leave the decision until the final week.

6. Let me narrow this down to the best lenders for your situation

I can make a more useful recommendation if I know a little about your mortgage. The best option for someone with a $250,000 mortgage and substantial equity may differ considerably from the best option for someone with a $900,000 mortgage.

Could you tell me these four things?

1. Who is your current lender? ANZ, ASB, BNZ, Westpac, Kiwibank, another bank?
2. Approximately how much is left on your mortgage? For example, $300k, $500k, $700k or $1m+.
3. How much equity do you have in your home? For example, 20%, 30%, 50% or more. An estimate is fine.
4. What's your priority?
   • A. Get the lowest possible interest rate.
   • B. Get the best overall deal, including cashback.
   • C. Have predictable repayments and minimise risk.
   • D. Pay the mortgage off faster, with flexibility to make extra repayments.

With those details, I can give you a ranked shortlist of the three lenders I'd approach first, explain why I'd choose them, and outline how I'd negotiate with your current bank before your rate expires.

With your fixed-rate home loan ending in two months, you’re in a good position to compare lenders before you automatically refix with your current bank. In Auckland, New Zealand, I’d compare the major banks with at least one smaller bank or specialist lender, and assess the total cost of switching rather than just the advertised interest rate.

My recommendation is to get competing offers before your current fixed rate expires, then negotiate with your existing bank. You may get a better deal without the paperwork and costs of moving.

The best lender for you will depend on your loan-to-value ratio (LVR), outstanding mortgage balance, income, whether you have a revolving-credit or offset facility, and how long you want to fix for.

The lenders I’d shortlist in New Zealand

These are the lenders I’d approach first, based on their mortgage options, potential value and reasons to include them in a comparison. This is a shortlist to obtain quotes from, not a claim that one bank is cheapest for every borrower.

1. ANZ

First quote to request

I’d include ANZ for its scale and as a useful competitor when negotiating. A May 2026 mortgage-adviser survey ranked it first among the major banks for overall lender performance. ANZ and non-banks fare well in mortgage broker survey

Best for: comparing a mainstream bank offer, particularly if you want to negotiate a sharper rate and cashback.

ANZ website

2. ASB

ASB is worth comparing for its digital banking experience and standard home-loan offering. It also publishes guidance on switching mortgages, including costs to consider. Switch your home loanANZ vs ASB vs BNZ vs Westpac NZ 2026 — Big Four Banks Compared

Best for: borrowers who value convenient online management and want a competing offer from another major bank.

ASB home loans

3. Kiwibank

My pick for an important alternative to the large Australian-owned banks. Kiwibank offers fixed, variable, offset and revolving-credit options, which can help if you want to tailor how your mortgage works. Fixed rate home loan | Home loansLoan options | Home loans

Best for: borrowers who want to compare a New Zealand-owned bank and potentially structure the loan around savings or extra repayments.

Kiwibank home loans

4. TSB

TSB is a useful challenger to include because it publishes its fixed-rate pricing clearly. Its published rates can give you another benchmark when comparing offers, although your eligible rate may differ. Home Loan Rates, Fees & Agreements

Best for: adding a smaller bank to the competition rather than relying solely on the big banks.

TSB rates and fees

5. BNZ

BNZ is worth including if you want offset or revolving-credit features. Its TotalMoney product can reduce the balance on which interest is calculated using eligible linked account balances. Home loan typesHome loan types

Best for: borrowers with meaningful cash savings or a preference for a more flexible loan structure.

BNZ home loans

I'd also get a quote from Westpac if it isn't your current bank, and consider The Co-operative Bank or SBS Bank as additional comparisons. You don't need to apply to all of them; a shortlist of three or four is a good starting point.

What matters most: the total deal, not just the rate

A lower advertised rate isn't automatically a better mortgage. Here's how I'd compare your options.

Factor	What I'd look for
Fixed interest rate	The best rate you're eligible for, on the same fixed term across lenders
Cashback	A competitive cash contribution, net of switching costs and any future repayment obligation
Switching costs	Legal fees, valuation costs if required, and any applicable charges
Repayment flexibility	Rules for extra repayments, lump sums and breaking a fixed term
Loan structure	Whether splitting the loan, offsetting savings or using revolving credit would benefit you
Service	How easy it is to get help and make changes to your mortgage

The Financial Markets Authority cautions borrowers not to be swayed by short-term cashback incentives without checking the longer-term costs and repayment conditions. Mortgage advice

When is switching worth it?

For example, on a $600,000 mortgage, a rate reduction of 0.20 percentage points is roughly $1,200 in first-year interest savings before accounting for principal repayments and other changes.

If switching costs you $2,000, that rate saving alone would take longer than a year to recover. Cashback could change the calculation, but check whether you'd have to repay it if you switch again within a specified period. Refinancing your mortgageSwitch your home loan

Your two-month action plan

1. Now: ask your current bank for its best refix offer.

   Request its lowest available rate for six months, one year and two years, plus any retention cashback or fee concessions. You can use this as your benchmark.

2. In the next two weeks: get competing quotes.

   Approach two or three other banks or use a mortgage adviser who compares multiple lenders. Ask for written offers based on the same loan amount, fixed term and equity position.

3. Compare the net benefit of moving.

   Calculate the interest savings plus cashback, less legal costs, valuation fees and any other switching expenses. Ask your current lender whether it will match the strongest competing offer.

4. Before your current rate expires: decide how to fix.

   Don't assume the lowest short-term rate will remain the best choice. Consider your budget, the repayment certainty you want and whether you may sell, renovate or make large extra repayments.

For a current market reference, the Reserve Bank of New Zealand publishes monthly mortgage-rate statistics, while individual lenders publish their own rates and eligibility conditions. Check both when you collect quotes, because rates can change before your refix date.

Let’s narrow this down to the best lenders for you

I can make a much more useful recommendation if I know a few details about your mortgage. In particular, your remaining balance and equity level can affect both the rates you qualify for and whether switching is financially worthwhile.

Your home loan

With those details, I can help you focus on the lenders most worth approaching first, rather than simply choosing whichever bank advertises the lowest rate.

Since your fixed rate ends in two months, this is a good time to shop around before your bank automatically rolls you onto a new rate. In Christchurch (and generally across New Zealand), I’d compare both the big banks and a few smaller lenders rather than assuming your existing bank is best. The right choice depends on your loan size, equity, income situation, and whether you value flexibility over the lowest rate. Canstar

Here are the lenders I’d put on your shortlist:

1. BNZ — strong all-round option

Why consider it:

• Good mortgage features, especially if you like actively managing your loan.
• Its offset-style BNZ TotalMoney structure can be valuable if you keep savings in linked accounts.
• Strong digital tools and generally a competitive refinancing proposition.

BNZ was recognised by Canstar as a leading home loan provider in its 2026 awards, with particular strengths in features and overall mortgage value. Canstar

Best for: borrowers with savings, multiple accounts, or who want flexibility.

---

2. ASB Bank — worth comparing for fixed rates

Why consider it:

• Often competitive on fixed residential rates.
• Good online banking experience.
• May be attractive if you already use ASB products.

ASB received recognition for residential fixed home loan value in Canstar’s 2026 awards. Canstar

Best for: straightforward owner-occupier mortgages where a competitive fixed rate matters.

---

3. Westpac New Zealand — particularly worth checking for longer fixes

Why consider it:

• Has historically competed well on some longer fixed terms.
• A refinance offer may include cash incentives depending on your circumstances.

Westpac was recognised for residential fixed home loan value, with strengths noted in longer fixed-term categories. Canstar

Best for: people considering locking in for 2–5 years.

---

4. Kiwibank — worth including if you prefer a NZ-owned bank

Why consider it:

• NZ-owned and often competitive on selected fixed terms.
• Worth using as a bargaining benchmark against the major banks.

Best for: borrowers who value a local ownership model and competitive pricing.

---

5. SBS Bank or The Co-operative Bank — don’t ignore smaller lenders

Why consider them:

• Smaller lenders sometimes compete aggressively on rates or service.
• The Co-operative Bank has performed strongly in floating and line-of-credit categories, while SBS has been recognised for some borrower-focused offerings. Canstar

Best for: borrowers willing to move away from the big four for a better deal.

---

Should you stay with your current bank?

I wouldn’t decide until you have a competing offer. Your existing bank already has your business, so it may offer a “retention” rate if you negotiate.

A practical approach:

1. Ask your current bank for its best refix rate, not just the advertised rate.
2. Get quotes from 3–5 competitors.
3. Compare:
   • interest rate
   • cashback/refinance contribution
   • legal/valuation costs
   • loan structure (offset, revolving credit, extra repayments)
   • break fees and flexibility

A difference of even 0.20%–0.30% can be meaningful on a large mortgage. Also, don’t focus only on the headline rate — fees and features can change the real cost. Giraffy

My shortlist for a Christchurch homeowner

If I were narrowing it down to a first round of enquiries, I’d ask for offers from:

1. BNZ
2. ASB
3. Westpac
4. Kiwibank
5. SBS Bank or The Co-operative Bank

Then take the best written offer back to your current bank and see if they will match it.

If you tell me:

• your remaining loan balance
• your current bank
• your home value (roughly)
• whether you want 1 year, 2 years, 3 years, or a split loan
• whether you have savings you could offset

…I can help compare which lender structure is likely to suit you best.

With your fixed-rate period ending in two months, you’re at a good point to shop around before your bank’s rollover offer becomes the default. In New Zealand, I wouldn’t choose a lender on rate alone — the best option depends on your equity, loan size, repayment style, and whether you value flexibility (offset, revolving credit, app, branch support, etc.). Current advertised rates and offers move frequently, so treat these as lenders worth approaching rather than a guaranteed “winner.” Canstar

For a Dunedin homeowner, these are the lenders I’d put on the shortlist:

1. Kiwibank — worth checking first

Why consider it

• Often competitive on fixed rates and promotes straightforward home-loan products. Kiwibank
• New Zealand-owned, which appeals to some borrowers.
• Good option if you want a simpler banking relationship and competitive pricing.

Potential downside

• Depending on your needs, the big Australian-owned banks can sometimes be more aggressive with retention discounts or complex lending structures.

2. ASB Bank — strong all-round option

Why consider it

• Competitive fixed-rate pricing and a strong digital banking experience. ASB Bank
• Good if you already use ASB accounts and want everything integrated.
• Usually a solid choice for borrowers who value service and online tools.

Potential downside

• The advertised rate may not be the final rate available to you; negotiate.

3. BNZ — often worth getting a quote from

Why consider it

• Historically competitive for borrowers with good equity and straightforward applications.
• Can be flexible if you want to structure lending across fixed portions, offset-style lending, or revolving credit.

Potential downside

• Their best deal may depend heavily on your profile and relationship.

4. SBS Bank — especially relevant in the South Island

Why consider it

• South Island roots and a reputation for competing for borrowers outside the largest banks.
• Smaller institutions can sometimes be more willing to negotiate.

Potential downside

• Check whether their product features match your needs.

5. The Co-operative Bank — worth including for comparison

Why consider it

• Has sometimes been very competitive on variable/floating pricing compared with larger banks. Financial Markets Authority
• Good if values and customer ownership matter to you.

Potential downside

• Smaller scale may mean fewer specialist lending options.

Should you stay with your current bank?

Before moving, I would give your existing bank a chance to compete. Ask them:

• “What is your best retention rate for my loan size and equity position?”
• “Can you match or beat this competitor’s offer?”
• “Is there a cash contribution available if I refix or restructure?”

Banks often have more room than their first offer suggests.

My shortlist approach for your situation

I’d probably get written offers from:

1. Your current bank
2. Kiwibank
3. ASB
4. BNZ
5. SBS or Co-operative Bank

Then compare:

• fixed rate offered (not just advertised)
• any cashback/cash contribution
• legal fees
• break fees
• ability to make extra repayments
• offset/revolving options
• whether moving costs outweigh the savings

A small rate difference can matter a lot. For example, on a $500,000 mortgage, a 0.50% lower rate is roughly $2,500 less interest per year initially (before considering repayment changes).

If you tell me:

• your loan balance
• estimated property value (or equity %)
• whether you want 1, 2, 3+ year fixed
• your current bank
• whether you’re in Dunedin city or a nearby area (only if relevant)

…I can help narrow this to the lenders most likely to beat your current deal.

With a fixed-rate loan ending in two months, I’d treat this as a good opportunity to shop around rather than automatically refix with your current bank. In New Zealand, your existing bank may offer a “retention” rate, but lenders often reserve their sharpest pricing for borrowers who are actively comparing. The best choice depends on your loan size, equity, income, repayment flexibility, and whether you value service over the lowest rate. Canstar

For a Wellington homeowner, these are the lenders I’d put on the shortlist:

Kiwibank

Why consider it

• Strong option if you prefer a New Zealand-owned bank.
• Often competitive on fixed rates and can be worth including in a refinance comparison.
• May appeal if local ownership and straightforward banking matter to you.

Best fit: borrowers who want a mainstream bank alternative and competitive pricing.

The Co-operative Bank

Why consider it

• Has been recognised for value in some home-loan categories, particularly floating and line-of-credit products. Canstar
• Customer-owned structure may appeal if you value a different banking model.
• Worth checking if you want flexibility rather than only chasing the lowest fixed rate.

Best fit: borrowers who value service, flexibility, and a smaller-bank relationship.

ASB Bank

Why consider it

• Frequently competitive among the large banks.
• Strong digital tools and a broad product range.
• Has received recognition for residential fixed home loans in industry comparisons. Canstar

Best fit: people wanting a polished online banking experience and a large-bank offering.

Westpac New Zealand

Why consider it

• Has been competitive at various fixed terms and has adjusted pricing as funding conditions changed. Westpac NZ
• Worth including if you are looking at longer fixed periods.

Best fit: borrowers considering 2–5 year certainty.

BNZ

Why consider it

• Offers useful features such as offset-style structures through products like TotalMoney. Canstar
• Good option if you keep savings or have multiple accounts you want working against your mortgage.

Best fit: borrowers who can benefit from offsetting savings against debt.

ANZ New Zealand

Why consider it

• One of the largest mortgage lenders in New Zealand.
• Large lending capacity and broad broker coverage.
• Some borrowers value the ability to negotiate, especially with a strong application. interest.co.nz

Best fit: borrowers who want a major bank and may negotiate through a broker.

What I would do in your position

With two months remaining, I’d usually:

1. Ask your current bank for its best retention offer

   • Don’t just accept the advertised rate.
   • Ask specifically: “Is this your sharpest refix rate, and can you match competing offers?”

2. Get quotes from 3–5 competitors

   • A mortgage broker can often compare lenders without you having to approach each one separately.
   • Include at least one smaller lender (Kiwibank, Co-operative Bank, SBS, TSB) and two major banks.

3. Compare the total package, not just the interest rate
   Look at:

   • cashback offers (and whether they require staying for a period)
   • legal fees for switching
   • loan splitting options
   • offset/flexible features
   • break costs if you later move or refinance

4. Think carefully about the fixed term
   Rather than automatically choosing the cheapest rate:

   • If you expect rates to fall, shorter terms or splitting the loan may give flexibility.
   • If you need certainty for budgeting, a longer fixed portion may be worthwhile.

A useful structure for many borrowers is splitting the loan, for example:

• part fixed for 1–2 years,
• part fixed longer,
• a small flexible portion (if useful).

If you tell me:

• your remaining loan balance,
• current interest rate,
• fixed term ending date,
• approximate home value/equity,
• whether you want lowest rate vs flexibility,

I can narrow this down to the lenders and fixed-term strategy I’d prioritise for your situation.
