What's the best bank for a first home loan if we're a salaried couple with about a 25% deposit?
For a salaried couple in New Zealand buying your first home with a 25% deposit, I'd start by comparing BNZ, Westpac, ANZ, ASB and Kiwibank rather than assuming one bank is automatically the best.
You're in a relatively strong position: a 25% deposit means you're borrowing about 75% of the property's value, which generally puts you in a better position than buyers with smaller deposits. You may have access to more competitive mortgage pricing and avoid the low-deposit lending restrictions that can apply to borrowers with less than a 20% deposit, subject to the bank's assessment.
The best bank for you will depend on the interest rate, cash contribution, lending flexibility and how much you can comfortably repay—not just the advertised rate.
My shortlist for your situation
1. ASB
Worth checking first
ASB advertises a $5,000 first-home-buyer cash contribution for eligible buyers borrowing at least $200,000. With a 25% deposit, this is worth asking about, although eligibility conditions apply. Home Loans & Mortgages
2. BNZ
A strong bank to include in your rate negotiations. Compare its special fixed rates and any cash contribution against ASB's total offer.
3. Kiwibank
Include it as a competitor when comparing interest rates and fees. Don't assume a larger bank will give you the best overall deal.
4. ANZ
Worth getting a competing offer from, particularly if you already bank with ANZ or want to negotiate a package around your income and deposit.
5. Westpac
Get a quote here too. The combination of negotiated interest rate, cash contribution and loan features may make its offer more attractive than the advertised rate suggests.
What interest rate should you aim for?
The Reserve Bank of New Zealand's September 2026 data puts average advertised special rates for new mortgages at approximately:
| Fixed term | Average special rate |
|---|---|
| 6 months | 4.74% |
| 1 year | 4.97% |
| 2 years | 5.27% |
| 3 years | 5.47% |

Check the live offers before committing, and ask each bank whether it can improve its rate or cash contribution. A difference of just 0.25 percentage points on a $600,000 mortgage is roughly $1,500 in first-year interest, before accounting for principal repayments.
How I'd approach the banks
- Get pre-approval based on your combined salaries, existing debts and expenses.
- Ask for the special rate and cash contribution together. Compare the total value rather than focusing on either one alone.
- Compare a one-year and two-year fixed option. Consider splitting the mortgage across different fixed terms if that suits your budget and risk tolerance.
- Check the cash contribution conditions. These can include minimum loan amounts and repayment obligations if you refinance or leave within a specified period.
- Consider a mortgage adviser who can compare multiple lenders and explain any differences in lending criteria.

Let me narrow this down for you
I can make a more useful recommendation if I know two things: how much you earn together and roughly how much you're looking to spend on the property.
