We're moving to a bigger home and may need to buy before our current place sells. Which lenders would you suggest we talk to about financing the move?
For a move-up purchase in New Zealand, I’d start by talking to your existing mortgage lender, then compare a couple of other major banks and an independent mortgage adviser. The key product to ask about is bridging finance — a short-term loan that lets you buy your next home before the sale proceeds from your current home arrive.
The right option will depend on how much equity you have in your current home, how much you need to borrow for the next one, and whether your existing property is already on the market. New Zealand’s Settled.govt.nz guidance also highlights the cost and risk of carrying two home loans at once. Thinking about your finances when sellingBridging Finance
Lenders I'd suggest contacting
- ANZ New Zealand
Offers bridging finance for buying before selling, with home loan coaches and mobile mortgage managers to discuss your options. A good bank to include in your comparison, whether or not you already bank with ANZ. Bridging Finance

Bridging finance and eligibility
- ASB
Worth approaching if you want to keep your existing mortgage in place while purchasing the next property. ASB says eligible customers may be able to use bridging finance, and it explains how buying and selling at the same time can be structured. Bridging finance - Buying & selling at the same time

Buying and selling a home at the same time
- BNZ
Particularly useful to ask about if your current home hasn't sold yet. BNZ explains the difference between open bridging (buying before your existing home is sold) and closed bridging (both sales are agreed, but settlement dates differ). It also discusses the evidence and repayment plan you may need. How bridging finance works
- Westpac New Zealand
Another option for a short-term increase to your existing home loan or a bridging loan. Ask whether your current mortgage can be transferred to the new property and how the bank would structure the temporary overlap. Options with your current homeSelling and buying - financial considerations
Westpac options for your next home
- Kiwibank
Worth comparing for its next-home lending options and calculator, which helps you estimate borrowing capacity when you might own two homes temporarily. Kiwibank also discusses using existing equity and transitioning your current mortgage. Confirm the specific bridging structure with a home loan specialist.

I'd also speak to an independent mortgage adviser who can compare several lenders' policies without you having to make separate applications to each bank. Check the adviser's credentials and the scope of their advice through the Financial Markets Authority's guidance. How do I find an adviser?Financial Advice Provider (FAP)
What I'd ask each lender
The important thing is to compare the whole financing arrangement, not just the advertised interest rate.
- Open versus closed bridging: Can you borrow before your current home has sold, or must you have an unconditional sale agreement?
- Maximum borrowing: Can you afford both mortgages under the lender's assessment, including the possibility that your home takes longer to sell?
- Interest and fees: What rate applies to the bridging portion, are payments interest-only, and are there establishment or valuation fees?
- Sale price assumptions: What happens if your existing home sells for less than expected?
- Loan structure: Can you transfer your existing mortgage, preserve a favourable fixed rate, or avoid unnecessary early repayment costs?
- Exit plan: What is the repayment deadline, and what happens if your home hasn't sold by then?
BNZ specifically highlights the need for a realistic sale appraisal and a backup plan. Government guidance also warns that bridging finance can mean paying for two home loans simultaneously. How bridging finance worksThinking about your finances when selling
My suggested next step
Start with your current bank and one independent mortgage adviser, then use the other banks above as comparisons. Ask for a written estimate of the temporary peak debt, monthly repayments and the costs if the sale is delayed.
To narrow this down to the most relevant options for your situation, roughly how much equity do you have in your current home, and have you listed it for sale yet? An approximate figure or range is fine.
