What's the best bank for bridging finance if we buy our next home before selling?
For New Zealand, I’d start with your existing bank, then compare BNZ and ANZ for bridging finance. The best bank will depend on how much equity you have, whether your current home is already on the market, and how comfortably you can afford both properties until the sale goes through.
Bridging finance lets you buy your next home before selling your current one. The key is to find a bank that will approve the total borrowing, offer manageable repayments during the overlap, and give you a workable exit plan once your existing home sells.
Which banks would I compare first?
1. BNZ — best starting point for an unsold home
BNZ clearly explains both open bridging (buying before your home is sold) and closed bridging (your sale is already unconditional). Its guidance also covers affordability, realistic sale valuations and backup plans. That makes it a good first conversation if you haven't sold yet. How bridging finance works
2. ANZ — worth comparing for a structured loan
ANZ offers bridging finance and can assess whether you can afford both loans during the transition. Ask for a written quote showing the interest rate, loan structure and repayment requirements. Bridging Finance
3. ASB — especially if you're already a customer
ASB may be able to keep your existing home loan and arrange additional lending for the new property. This is worth exploring if you have a fixed-rate mortgage you don't want to restructure unnecessarily. Bridging finance - Buying & selling at the same time
4. Westpac — another option for existing borrowers
Westpac says it may be able to increase your existing home loan temporarily or arrange bridging finance. Compare its proposal with your current lender's offer. Options with your current home

These are my suggested banks to approach, not a verified ranking of approval rates or the cheapest bridging interest rates. The published information doesn't establish one universal winner.
What matters more than the bank's name?
- Open vs closed bridging: If you haven't sold your existing home, you need open bridging. If you've signed an unconditional sale agreement, closed bridging may be more straightforward.
- Interest and repayments: Ask whether interest-only payments are available on the bridging portion and how much you must pay each month across both properties.
- How long you have to sell: Check the maximum term and what happens if the sale takes longer than expected.
- Your fallback plan: Model what happens if the home sells for less than expected or takes several months longer to sell. Settled.govt.nz also highlights the cost and risk of carrying two home loans. Thinking about your finances when sellingHow bridging finance works
Let’s narrow it down to the best option for you
I can give you a more useful recommendation if you share a few figures. Rough estimates are absolutely fine.
Estimates in NZ dollars are fine. Leave any field as-is if you're unsure.
With those details, I can help estimate the likely bridging gap and identify which banks are most worth approaching first. Approval will ultimately depend on the lender's assessment of your income, equity, expenses and sale plan.
