My partner and I run a business and bought our home last year. Our income is uneven, and our bank treats us like salaried customers whenever we ask about our repayments. Are there banks that are better for self-employed homeowners?
Yes. In New Zealand, there are banks and mortgage lenders that may suit self-employed homeowners better, particularly when your business income arrives in uneven amounts rather than as a regular salary.
The key distinction is that some lenders are better at accommodating irregular cash flow, while others are better at assessing self-employed income. Those are two different problems, and you and your partner may need solutions for both.
Since you bought your home last year, I'd look at two things: whether your current lender can restructure your mortgage to fit your cash flow, and whether another lender would assess your business income more fairly if you refinance.
1. New Zealand banks worth looking at
These are good places to start based on their published home-loan features. They aren't necessarily ranked by how lenient they are towards self-employed borrowers.
1. Kiwibank
Strong option for irregular cash flow
Kiwibank offers a revolving-credit home loan designed for people whose income varies. It works much like an overdraft: money can be paid in when business income arrives, reducing the balance on which you pay interest, and accessed again when needed.

Best for: Business owners who receive large or irregular payments and need to manage quiet periods between invoices.

2. ANZ
ANZ's Flexible Home Loan has no set repayments while you stay within your approved credit limit. You can deposit income and redraw funds as needed. The trade-offs include a potentially higher interest rate, a monthly fee and the bank's ability to review the facility.

3. ASB
ASB offers a revolving-credit home loan that allows you to repay and redraw money within an approved limit. This can be useful if your business income fluctuates and you have good cash-flow discipline. Revolving mortgage - Giving you flexibilityShaping your loan payments
Best for: Business owners who want their available cash to reduce mortgage interest, while retaining access to a reserve.

One important caveat: flexible repayments don't automatically mean more flexible lending assessments. A bank can offer a revolving mortgage but still assess your ability to service it using conservative calculations of your self-employed income.
2. What about banks that assess self-employed income better?
If your frustration is that the bank doesn't understand how your business earns money, I'd consider a mortgage adviser who regularly works with self-employed clients and can compare lenders' assessment criteria.
Mainstream banks often ask for two years of annual business financial statements. For company directors and business owners, the way you pay yourself, retain profits in the company, and claim business expenses can affect the income a lender recognises. Some lenders may consider alternative evidence or have different policies. Preparing for a home loan appointmentHow NZ banks assess self-employed income for a mortgage
A useful distinction:
- If your business is profitable but your personal drawings vary: ask how lenders treat retained earnings, dividends and legitimate add-backs to business profit.
- If your income varies significantly from year to year: ask whether the lender averages income over multiple years or puts more weight on the most recent year.
- If your accounts don't reflect your current earnings well: ask whether any lender can assess your situation using additional financial evidence. Specialist or non-bank lending may be an option, but check the interest rate, fees and exit strategy carefully.
I wouldn't assume you need to leave a major bank. A better-prepared application, or a different loan structure with your current bank, could be enough.
3. The mortgage structure I'd investigate first
For a couple running a business, one common approach is to split the mortgage into two parts:
Part A: Fixed-rate home loan
Keep most of the mortgage on predictable repayments, so you know the minimum amount you need to cover each month.
Part B: Revolving-credit or offset facility
Use surplus business income, once tax and business expenses are covered, to reduce interest or build a cash buffer. The exact setup depends on your lender and how your accounts are structured.
This arrangement can give you some payment certainty without losing all flexibility. However, revolving credit is not free money: the interest rate may be higher, and repeatedly redrawing the balance can slow your mortgage repayment.
4. What I'd do in your position
- Ask your current bank for a review specifically with a home-loan specialist who understands self-employed borrowers.
- Speak to an independent mortgage adviser who can compare several banks and, if appropriate, specialist lenders.
- Have your last two years of financial statements, recent management accounts, tax records and a clear picture of business cash flow ready.
- Compare the total cost of switching, including any fixed-rate break fees, legal costs and changes to interest rates.
