Best banks in New Zealand for bridging finance
If you want to buy your next home before selling your current one, I’d start by comparing ANZ, BNZ, Westpac and ASB. All four have information about bridging finance or options for buying and selling at the same time. The best bank for you will depend on your existing mortgage, how much equity you have, your income and how quickly you expect to sell your current home.

My shortlist
- ANZ — a good first option to investigate
ANZ offers bridging finance to help you buy without selling first. It explicitly highlights the need to afford both loans while you wait for your existing property to sell.
Best to investigate if you want a straightforward bridging loan and clear advice on affordability.

- BNZ — worth comparing for open bridging
BNZ explains both open bridging (you haven't sold yet) and closed bridging (your existing home is sold unconditionally). Its guidance discusses interest-only payments on some lending and bridging periods of up to 12 months, subject to approval.
Best to ask about the maximum bridge period and repayments if your house takes time to sell.

- Westpac NZ — worth checking if you already bank there
Westpac says it may be able to temporarily increase your existing home loan or arrange bridging finance when you buy before selling.
Best to investigate whether adjusting your current mortgage is simpler than setting up separate bridging finance.

- ASB — another strong comparison option
ASB describes bridging loans and options for existing customers who want to use their new property as security under a new mortgage.
Best to investigate if you want to keep your existing lending relationship and restructure your home loans.

Which bank would I choose?
My practical recommendation is to ask your current bank for a bridging finance quote first, then get a competing quote from one other bank. Moving your mortgage to a new bank can add paperwork and settlement coordination.
Compare these four things:
- Total borrowing approved: Will the bank lend enough to complete the new purchase while your current mortgage remains outstanding?
- Repayments during the bridge: Can you afford both mortgages, rates, insurance and other costs?
- Time allowed to sell: What happens if your current house takes 3–6 months or longer to sell?
- Interest rate and fees: Ask for the actual rate, any establishment or valuation fees, and the total estimated interest cost.
The banks' published guides don't establish one universally cheapest option, so I wouldn't choose based on the bank name alone.
Let’s narrow it down to the best option for you
I can help you work out which bank is most suitable if you tell me a little about your situation.
With those details, I can help estimate the equity tied up in your current home and the temporary funding gap, then suggest which banks to approach first.
