We bought our first rental last year and now have two mortgages with the same bank. It's been hard to get advice on how to set the loans up. Are some banks better at supporting landlords with more than one property?
Yes — in New Zealand, some banks may be a better fit for landlords who own multiple properties, particularly when it comes to how they assess rental income, release equity, structure loans and support future purchases. But the quality of the lending advice and the way your mortgages are structured can matter just as much as which bank you use.
Since you've already bought your first rental and have two mortgages with the same bank, I'd focus on two things: whether your current loans are set up well for your long-term plans, and whether another lender could offer more flexibility.
What makes a bank good for property investors?
These are the main differences I'd look at when comparing New Zealand lenders.
- Portfolio lending: How well the bank assesses your overall financial position across your home and rental property, rather than treating every new purchase as an isolated application.
- Equity access: How straightforward it is to use available equity towards another deposit, subject to lending criteria.
- Loan structure: Whether you can keep lending for each property separately, rather than unnecessarily tying multiple properties together as security.
- Rental income assessment: How much of your rental income the bank recognises when calculating what you can afford to borrow.
- Repayment flexibility: Whether it offers suitable fixed-term splits, revolving-credit facilities or interest-only periods, where appropriate.
- Relationship management: Whether you can get advice from someone who understands investment lending and can plan with you beyond your next mortgage refix.
For example, ANZ's published investment-property guidance discusses using equity across multiple properties, subject to its lending criteria. Westpac also has specific investment-property lending policies. These are useful starting points, but they don't establish that either bank is best for every landlord.

Which New Zealand banks should you compare?
I'd start by asking for a comparison across these lenders rather than assuming you need to move.
ANZ New Zealand
A useful starting point if you want to understand how equity across your home and rental could support future borrowing. Its published guidance specifically discusses combining equity across properties. Borrowing for an investment property

Westpac New Zealand

BNZ
Ask for an assessment of your combined household and rental-property finances, and whether its lending structure would give you better flexibility for another purchase.

Kiwibank
Another lender to benchmark against your current bank on rates, equity requirements, loan splits and the treatment of rental income.

These are lenders to compare, not a ranking of which bank is best for landlords. Their suitability depends on your equity, income, existing debt and plans.
One thing I'd investigate before switching banks
Check whether your two properties are cross-collateralised.
This means the bank uses both properties as security for your borrowing, rather than keeping the security arrangements separate.
- Linked securities: Can make the overall lending arrangement convenient, but selling one property or moving one loan may require the bank to reassess the wider arrangement.
- Separate securities: May give you more flexibility to refinance or sell one property independently, although the bank still assesses your overall ability to repay.
You can ask your current bank whether each property can support its own loan facilities and what would be required to release either property from its security.
Also, avoid switching just for a slightly lower interest rate without checking any cashback repayment obligations, break fees and legal or valuation costs.
Don't overlook New Zealand's lending rules
As at October 2026, Reserve Bank restrictions remain relevant when you want to expand a rental portfolio:
- Loan-to-value ratios (LVRs): Banks can generally lend up to 70% of an investment property's value under the standard investor threshold, with limited allowances for higher-LVR lending.
- Debt-to-income ratios (DTIs): Investor borrowing above seven times gross annual income is considered high-DTI lending. Banks can make a limited proportion of new loans above that threshold.
These are limits on banks' lending, not guarantees that you'll qualify to borrow up to those levels. Banks also apply their own affordability assessments.

My recommendation: find a mortgage adviser who specialises in property investors
Rather than relying solely on your bank's lending manager, consider a mortgage adviser who regularly works with landlords building a portfolio. Ask them to compare several lenders and provide a written explanation of the recommended structure, including its trade-offs.
The New Zealand Financial Markets Authority recommends asking advisers which lenders they cover, how they're paid, why they recommend a particular loan and what fees or early-exit costs may apply. Mortgage adviceWorking with a financial adviser
You can use the FMA's mortgage advice guide to help assess an adviser.
Can I narrow this down for you?
One question first: are you hoping to buy another rental property in the next few years, or are you mainly wanting to get your existing two mortgages structured properly?
That makes a difference to whether I'd focus on future borrowing capacity, loan flexibility, or simply improving the arrangement you already have.
