Which bank is best for flexible mortgage repayments if you're a contractor who just bought your first home?
For a contractor who has just bought their first home in New Zealand, I’d start by comparing Kiwibank and BNZ, particularly if you want to make larger mortgage repayments when work is busy, keep more cash available between contracts, and avoid being locked into rigid repayment rules.
The best bank depends on what you mean by flexibility: being able to make extra repayments, being able to redraw money in a quiet month, or reducing interest on the cash you keep in reserve.
My top bank choices
1. Kiwibank
My first choice to compare
Best if you want flexible repayments and a buffer for quieter contracting periods.
- Its revolving credit home loan has no fixed repayment periods and works like a large overdraft.
- Its offset loan lets you make extra repayments whenever you like without a fee.
- You can combine fixed, variable, offset and revolving portions. Revolving home loan | Home loansOffset home loan | Home loans
Watch out: Revolving credit needs disciplined budgeting, and money paid directly into an offset loan generally cannot be withdrawn again.

2. BNZ
Best if you build up savings in your business or personal accounts between contracts.
- TotalMoney offsets your mortgage interest against balances in linked transaction accounts.
- You can link up to 50 eligible accounts.
- The loan is floating, allowing flexible repayments and lump sums. TotalMoney home loans - Offset mortgagesHome loan types
Watch out: The floating rate can be higher than a fixed rate, and offsetting works best when you regularly maintain a cash balance.
3. ANZ
Best if you want to make irregular payments and retain access to borrowed funds.
- Its Flexible Home Loan has no set repayments while you stay within the approved credit limit.
- You can pay money in and redraw it when needed.
- ANZ notes that this option often has the highest interest rate and a monthly fee. Flexible MortgageFloating mortgage
Watch out: You need strong cash-flow management to avoid continually reusing the credit you've paid off.

What I would do in your position
For a first-home mortgage with contractor income, I would usually consider a split mortgage:
- Most of the mortgage on a fixed rate: provides predictable minimum repayments.
- A smaller portion on an offset or revolving facility: lets you use surplus income to reduce interest while keeping appropriate access to cash.
- A separate emergency fund: covers tax, GST if applicable, business expenses and gaps between contracts.
For example, if you have a $600,000 mortgage and can reliably keep $25,000 in accessible savings, an offset loan could let you pay interest on a smaller effective balance. The actual saving depends on the offset rate, fees and how long that cash remains available.
If your mortgage is already in place, check the early repayment rules before making changes to any fixed-rate portion.
One important consideration for contractors
Loan flexibility is only half the decision. Banks can assess self-employed income differently, and some will want to see two years of business financial statements or tax returns. BNZ, for example, lists the last two annual business financial statements among its evidence options for self-employed applicants. Preparing for a home loan appointmentGaining pre-approval
If you already have your mortgage, you can focus on the repayment features and any costs involved in restructuring. If you're still choosing a lender, compare how each bank assesses your contracting income as well as its interest rates.
Let me narrow it down for you
The most important question is: what kind of repayment flexibility do you want most?
