How New Zealand Banks Treat Australian Income and Deposits

If you're an Australian citizen, an Australian permanent resident, or a New Zealand citizen living in Australia, “can I get a mortgage” isn't one answer. Lenders take genuinely different views of offshore income, deposits and documentation, and the right fit for your situation depends on specifics a general page can't capture. This article describes general patterns we see across New Zealand lenders, for general information only, not personalised financial advice. It isn't a complete survey of every lender, and your own situation may be assessed differently. It's the detail behind the summary in our main guide to buying property in New Zealand as an Australian.

Who generally gets considered

Most major banks will consider an application from a New Zealand citizen living in Australia; this is the most straightforward starting position. Fewer extend the same openness to Australian citizens who've never lived in New Zealand, and the field narrows further again for Australian permanent residents who don't hold New Zealand residency themselves.

Where it gets complicated: dual citizenship, a recent change in residency status, or a permanent-residency-only applicant can all shift which lenders are realistically in play. These aren't edge cases we see rarely. They're common enough that it's worth establishing your exact status before you start looking at properties, not after.

How Australian income generally gets assessed

Most major banks don't take Australian salary and wages at face value. They apply some form of discount to account for currency and policy risk, commonly landing in a broad 80 to 90% range of net income, though the exact approach varies and isn't applied identically everywhere.

Variable income (overtime, bonus, commission) is typically treated more conservatively again, and self-employment income earned in Australia is the hardest to get accepted. Some lenders exclude it entirely for offshore applicants; others will consider it with the right documentation. A handful of non-bank lenders can be more flexible on paper, but their actual willingness to lend to someone living and earning in Australia needs confirming directly. It isn't something to assume from their general marketing material.

Worth knowing from real experience, not just policy documents: how your income gets treated can depend as much on how the application is put together and presented as it does on a fixed rule. One recent case involved an Australian company director with strong income and a high net worth, buying a property in Queenstown intended partly as a personal holiday home and partly as an investment. That mixed use didn't fit neatly into a mainstream bank's standard categories, so the application went to a specialist non-bank lender instead, which assessed the Australian income on its own terms and settled at a 70% LVR. Net worth alone didn't make the application straightforward. Getting the structure and presentation right is what did, which is exactly the kind of thing a broker can influence and a generic calculator can't.

Deposit requirements, in general terms

Most banks expect a larger deposit from an overseas-based borrower than from someone buying their own home while living in New Zealand, though it's not as simple as “overseas always means 30%.” Several lenders will still go as low as 20% for New Zealand citizens with qualifying Australian income, in the right circumstances.

Investment purchases, and buying before you've actually relocated, typically sit at a higher tier, often around 30%, more or less regardless of citizenship. Genuine holiday homes with little or no rental activity tend to sit somewhere in between, and how a lender classifies your purchase (owner-occupied versus investment) usually matters more to your deposit requirement than almost anything else.

Where it gets complicated: this classification isn't always obvious upfront, and two people in very similar-looking situations can land in different categories depending on how imminent their move is, how a lender reads their intentions, and even which specific product within the same bank they end up assessed under. For the detail on deposit tiers by scenario, see our deposit and LVR guide for overseas buyers.

Documentation, in general terms

Expect to provide the standard set: identity documents, payslips or employment evidence, bank statements, and evidence of your deposit and where it came from.

Beyond that, a few lenders have their own extra steps for new offshore customers. Some require an in-branch visit to open an account before final approval; others apply additional identity or source-of-funds checks specific to living overseas. This varies enough between lenders that it's worth asking early, especially if you're planning to settle remotely, rather than assuming your experience will match what a friend or forum post describes for a different bank.

Why this is worth a conversation, not a web search

The honest answer to “which bank should I use” depends on your citizenship and residency status, how your income is structured, your deposit, and how the property will be used, and those combinations don't reduce neatly to a lookup table. We see the full range of these situations regularly, and matching a specific application to the lender most likely to say yes, with the income and deposit presented the way that lender actually assesses it, is a meaningful part of what a broker does. It's also exactly the kind of judgement that doesn't come from reading a general page like this one.

Frequently Asked Questions

Do all New Zealand banks treat Australian income the same way?

No. Every lender takes its own approach to how much Australian income counts, how variable income like bonuses is treated, and what documentation it wants. The patterns in this article are general; your own situation needs checking against current policy.

Is it harder to get a mortgage as an Australian permanent resident than as a citizen?

Generally yes. New Zealand citizens living in Australia tend to have the widest range of options, Australian citizenship narrows the field a little, and Australian permanent residency without New Zealand residency narrows it further again. It still depends on the specific lender and your situation.

Will a non-bank lender definitely be more flexible than a mainstream bank?

Not necessarily. Non-bank lenders can look more flexible on paper for income and documentation, but whether their terms actually extend to someone living and earning in Australia needs confirming directly, not assumed from general marketing material.

How do I find out which lender suits my specific situation?

Speak with a mortgage adviser who works regularly with cross-Tasman buyers. Your citizenship, income structure, deposit and intended use of the property all affect which lenders are realistically available to you, and that combination is hard to work out from general information alone.
