We're a salaried couple buying our first home with about a 10% deposit and little experience with mortgages. What matters most to us is being able to pay extra or change our repayments when we need to. Which lenders would you recommend for our home loan, and why?
For you as a salaried couple buying your first home in New Zealand with around a 10% deposit, I'd prioritise repayment flexibility over simply getting the lowest advertised interest rate.
The key is choosing a lender that lets you put extra money towards your mortgage when you can, reduce your repayments when circumstances change, and avoid unnecessary break fees or refinancing costs.
One important distinction: being allowed to make extra repayments is not the same as being allowed to lower your regular repayments whenever you want. Most fixed-rate loans restrict both the amount of extra money you can pay and the changes you can make to your scheduled repayments.
Which lenders I'd shortlist
I'd compare these five lenders first, focusing on their mortgage structures and rules rather than just their headline rates.
1. Westpac New Zealand
Best fit for repayment changes
Westpac is particularly worth investigating because eligible customers can increase or decrease their repayments online, within their loan agreement. Its Choices Fixed loan allows repayment increases of up to 20% above the minimum, and you can reduce them again when needed. Choices Fixed home loanHow do I change my loan repayments online? - Help
Why it suits you: This is the clearest match if you want to be able to adjust your regular payments rather than just make occasional lump sums.
Watch out: The 20% cap applies to increases on the fixed loan, and your eligibility and exact loan terms matter. A 10% deposit may also mean a low-equity margin or different pricing.
2. Kiwibank
Best all-round flexibility to explore
Kiwibank offers fixed, variable, offset and revolving-credit options. On a fixed loan, you can make extra repayments up to 5% of the original loan amount at the start of the fixed term each year. Its variable loan allows extra repayments at any time, and it describes revolving credit as its most flexible option. Fixed rate home loan | Home loansMaking changes to your loan | Home loans
Why it suits you: You can potentially combine predictable repayments on a fixed portion with a flexible portion for extra payments or cash reserves.
Watch out: Variable and revolving rates can be higher, and a revolving facility requires discipline so you don't end up reusing the money you've paid in.
3. BNZ
BNZ is worth comparing for its mix of fixed, floating, offset and revolving-credit loans. Its standard fixed loan allows extra repayments of up to 5% of the loan balance each year without an early repayment charge; floating loans allow extra or lump-sum payments without that charge. Its TotalMoney offset loan can also link eligible transaction accounts to reduce the balance on which interest is calculated. Home loan typesTotalMoney home loans - Offset mortgages
Why it suits you: A good option if you want flexibility with savings and spare cash, while keeping some of your mortgage on a predictable fixed rate.
Watch out: Offset arrangements reduce interest rather than automatically reducing your required scheduled repayment.
4. ASB
ASB lets eligible fixed-loan customers increase repayments by up to $500 per fortnight or $1,000 per month without an early repayment adjustment, provided the higher repayment is maintained for the rest of the fixed term. Its floating loan permits extra repayments without early repayment adjustments. Fixed rate home loan & mortgage - View latest ratesFloating mortgage & home loans - View rates online
Why it suits you: The fixed-loan increase allowance may be useful if you expect regular pay rises or want to gradually accelerate your repayments.
Watch out: Its fixed-loan increase option isn't designed for repeatedly raising and lowering payments during the term.
5. ANZ New Zealand
ANZ offers fixed, floating and flexible home loans. On a fixed loan, you can generally increase regular repayments by up to $250 a week on the first increase in a fixed-rate year without an early repayment recovery, and make an additional lump-sum repayment of up to 5% of the current loan amount each year. Its Flexible Home Loan has no set regular repayments while you remain within the credit limit. Fixed mortgagesChanging your mortgage repaymentsFlexible Mortgage
Why it suits you: The flexible loan is worth considering if you want to put your salary into the loan and redraw money when needed.
Watch out: Flexible lending usually has a higher interest rate and an account fee. I'd be cautious about putting too much of your first mortgage into this structure.
How I'd structure your mortgage
For your priorities, I would ask all five lenders to quote the same loan using a split mortgage rather than putting the entire loan on one fixed rate.
An example structure to discuss
80–90% on a fixed rate
Provides repayment certainty and helps you budget for your essential bills.
10–20% on a floating or offset rate
Lets you make additional repayments more freely, and an offset loan may let your savings reduce interest while remaining accessible.
Illustrative proportions only, not a personalised borrowing recommendation. A lender may require a different structure, and the flexible portion may have a higher interest rate.
For example, when you receive a bonus or have a month with lower expenses, you could put extra money into the flexible portion without worrying about the usual fixed-loan early repayment restrictions. Keep an emergency fund accessible rather than putting every spare dollar into the mortgage.
If you choose a split loan, make sure the flexible portion is large enough to be useful but not so large that its higher interest rate unnecessarily increases your costs.
What matters particularly with a 10% deposit
With around 10% deposit, you'll generally be borrowing about 90% of the property's purchase price. That makes it important to compare more than the advertised interest rate.
Ask each lender about:
- Low-equity pricing: Is there a low-equity margin or premium, and when could it be removed as your equity grows?
- First-home lending criteria: Will they approve your deposit size and employment/income situation?
- Cashback and fees: Compare any cash contribution, account fees and the conditions attached to offers.
- Repayment reductions: Can you reduce your regular payment during a fixed term, or would you need to apply for a temporary change?
- Financial hardship options: What happens if one of you loses income or needs parental leave?
A 10% deposit doesn't automatically rule out the lenders above, but approval and pricing will depend on their criteria and your circumstances.
My final recommendation
I'd start by getting quotes from these three:
- Westpac — first choice to investigate because its fixed-loan repayment settings explicitly allow eligible borrowers to increase and subsequently reduce payments within the applicable limits.
- Kiwibank — a strong alternative if you want to compare fixed and flexible loan structures, including offset and revolving credit.
- BNZ — particularly worth comparing if you have savings that could make an offset mortgage useful.
Then compare ASB and ANZ against the same borrowing amount and loan structure. The best choice could change once you see your actual low-equity pricing and the conditions of your approval.
Because you're new to mortgages, I'd also consider speaking with a reputable New Zealand mortgage adviser who can explain the trade-offs and compare lenders for you.
