best bank for construction loan on own land
If you already own the land in New Zealand and want to build a house on it, I’d compare ANZ, ASB, BNZ, Westpac and Kiwibank before choosing a construction loan.
The best bank depends on how much equity you have in the land, whether you have a fixed-price building contract, your income, and whether you’re building with a registered builder or managing the project yourself.
The key advantage of owning the land: its eligible equity may count towards your deposit, so you might not need to contribute as much additional cash. The bank will still assess your borrowing capacity, the land’s value, the proposed finished property and the construction risks.
My top picks for a construction loan
1. BNZ — best starting point for a standard build
BNZ offers staged payments as construction progresses, interest-only repayments during the build may be available, and you pay interest on funds already drawn. Worth comparing if you already own the section and have a builder lined up. Construction loans - Buying land and building a houseHow to borrow to build a brand-new home
2. Westpac — worth checking for lower-deposit options
Westpac advertises construction lending of up to 90% of the construction contract price for eligible projects, depending on the contract and lending assessment. It also offers staged drawdowns and interest-only options during construction. Finance your projectNew Build Loan
3. ANZ — worth comparing for new-build benefits
ANZ has dedicated Construction Coaches and a Blueprint to Build package that may offer discounted interest rates and fee savings for eligible new builds. Ask how the package applies when you already own the land. ANZ Blueprint to build package | For new build homesFinancing your building or renovation project
4. ASB — worth comparing for flexible project arrangements
ASB offers progress-payment lending for different build types, including fixed-price and labour-only contracts. It specifically recommends checking the contract with both your lawyer and lender before committing. Building or renovating your home?
5. Kiwibank — another good comparison
Kiwibank assesses your income, land value, construction cost and estimated finished-home value. It uses staged drawdowns and may require progress certification and valuations. Borrowing to build | Home loans
These are my suggested banks to approach, not a verified ranking of the cheapest current rates. The best offer will depend on your circumstances and the bank's assessment.
What matters most when you already own the land?
Ask each bank for these four things:
- How much of your land equity counts towards the deposit? Request a calculation using the current land value and any existing mortgage.
- What rate applies during construction? The construction portion is often floating, and you typically pay interest only on the amount drawn.
- What contract types will they finance? A fixed-price contract can be easier to finance than a labour-only or owner-managed build.
- What cash buffer is required? You may need funds for overruns, consent fees, valuations and expenses that are not covered by the loan.
