Can the Bank Decline Your Mortgage Because of Debt, Spending or Your Bank Statements?
Last reviewed: 9 October 2026. Reserve Bank settings and lender policies change, so check the linked sources for the current position.
If your home loan has been declined, do not immediately apply to another bank. A decline usually reflects one part of the assessment, not the whole application. The common factors are serviceability, existing commitments, deposit size and source, credit history, what your bank statements show about debt and spending, and how your income is evidenced. Which one applied to you decides what to do next. So it’s worth asking before you use another application.
Start here: do not reapply yet
If your home loan has been declined, the most useful thing you can do in the first week is nothing at all, at least in terms of new applications.
I see people go straight to the next bank, and I understand why. It feels like momentum. But each application generally creates a credit enquiry on your file. A run of them in a short period is visible to the next lender. More to the point, if you don’t know which part fell short, the second application will likely hit the same wall.
The question I ask first when someone comes to me after a decline is simple: what number were you assessed at, and what did you need? Quite often nobody has told them. That single figure is what separates a problem you can fix this month from one that takes considerably longer.
What a decline usually means
Someone posted in a New Zealand first home buyers group I help moderate that they had been told no for the third time. They had a substantial deposit, some consumer debt, and a business they had run for over two years. They were also paying more in rent each week than the mortgage would have cost. The thread ran to a few hundred comments in a day. Roughly half said pay the debt down first. The other half said find a different adviser.
Both camps were partly right, which is unsatisfying but true.
A decline is rarely a judgement on whether you are good with money. Lenders combine a calculation with a broader credit review. They weigh your income and commitments against their policy. They also look at your credit history (see my bad credit options if yours is patchy) and the property itself. Somewhere in that process a figure came out lower than the loan you needed, or something in the wider picture did not meet policy.
The useful question is which part, because the fixes are not interchangeable. Reducing a credit card limit is a short piece of work. Rebuilding a credit history after arrears is not.
Serviceability: what the lender is testing
Serviceability, sometimes called the affordability assessment, is a lender calculation that checks whether you could still meet the repayments if interest rates were higher than they are today. It is one of the more common places an application falls short, in my experience.
This is the part clients find hardest to accept, and I think that is fair enough. You can be paying well above the likely mortgage repayment in rent, on time, for years. A strong rental history is useful context, and some lenders will consider it. However, it doesn’t replace the lender’s own affordability test, because that test asks a different question.
It is testing the repayment at a rate above the advertised one. Test rates vary between lenders and move over time, and they can sit materially higher than the rate you would actually be charged. On top of that the lender adds rates, insurance and an estimate of your household living costs.
Living costs are worth getting right
Lenders compare the living expenses you declare against their own benchmark for a household like yours. If your figure looks low against that benchmark, they may use theirs instead. Also, a gap between your stated costs and your bank statements tends to invite questions.
So trimming spending genuinely helps, because it shows up in your transactions over time. Writing down a smaller number on the form, on its own, generally does not.
Test rates are set by each lender as a matter of credit policy, not prescribed by the Reserve Bank. Two lenders looking at the same financials can reach noticeably different borrowing figures, which is a large part of why where an application goes matters.
Existing commitments and credit card limits
This is the area I see move the number most often, and it is usually the quickest to act on.
A personal loan or car loan is generally assessed on its repayment rather than its balance. Lenders subtract that repayment from what you have available for a mortgage. So a modest-looking loan with a high repayment can cut your borrowing more than you’d expect.
Credit cards work differently again. Most lenders assess against the limit rather than the balance, on the basis that you could draw the full limit at any time. A card you clear every month, or never use, can still be treated as an ongoing obligation. Buy now, pay later arrangements also show up in your transactions and can form part of the picture.
If your deposit and income are sound, reducing commitments is often the most valuable change. Better still, it takes weeks rather than years. If you close a card, ask for written confirmation, because the assessor will usually want to see it.
Consolidating debt into the mortgage comes up a lot in this conversation. It can help in some situations and make things worse in others, particularly by stretching a short-term debt over thirty years. It is worth working through properly rather than treating it as a default move.
More on this: how credit cards affect your home loan approval.
Not sure which part of the assessment stopped you?
We can discuss what may have caused the decline and what your options could be.
Debt-to-income restrictions
A debt-to-income ratio, or DTI, compares your total borrowing against your gross annual income. Since 1 July 2024 the Reserve Bank has restricted the share of high-DTI lending banks can write. Banks may write up to 20 percent of new owner-occupier lending to borrowers with a DTI above 6, and up to 20 percent of new investor lending to borrowers with a DTI above 7.
The distinction matters, and it is one I find is widely misunderstood. Six and seven are not absolute borrowing caps. They are thresholds, and the restriction is a speed limit on how much lending above those thresholds a bank can do. In fact, banks do lend above them, within their allocation and policy.
Two practical consequences follow.
The first is that a larger deposit does not directly resolve a DTI issue, because DTI is measured against income rather than equity. A larger deposit does reduce the loan amount, which lowers the ratio, but it does not lift your income.
The second is that a bank may or may not use its high-DTI allocation on you. That depends on the rest of your file and the lender’s appetite at the time. There are also exemptions, including new builds and Kāinga Ora lending.
| What fell short | What tends to help | Indicative timeframe |
|---|---|---|
| Serviceability | Reducing commitments, strengthening evidenced income, a lender whose policy suits you better, a longer term, or a lower purchase price | Weeks to months |
| Credit card limits | Reducing or closing limits, with written confirmation | Days to weeks |
| Other consumer debt | Reducing the commitments that weigh most heavily on serviceability | Weeks to months |
| Debt-to-income ratio | Higher income, a smaller loan, or a lender with allocation and appetite | Varies |
| Deposit below 20 percent | First Home Loan if eligible, low-deposit lending, or a larger contribution | Varies |
| Deposit source not yet evidenced | Gifting documentation, and a savings record where the lender requires one | Varies by lender |
| Missed payments, arrears or defaults | Time and consistent conduct. Recency, size and the lender’s policy all matter | Depends on the circumstances |
| Self-employed with a shorter trading history | Stronger supporting evidence, or a lender whose policy accommodates it | Varies |
Deposit, LVR and where the money came from
A deposit that sounds large can still be under 20 percent of the price. That puts the application into low-deposit territory.
The Reserve Bank limits the share of high-LVR lending banks can write. As at August 2026, banks may write up to 25 percent of new owner-occupier lending above 80 percent LVR, and up to 10 percent of new investor lending above 70 percent LVR. So low-deposit lending is rationed, not banned. Appetite also varies between lenders and over time. Notably, Kāinga Ora lending, including First Home Loans, is exempt from the LVR rules. That’s why it’s worth checking if you’re eligible.
Where the money came from can matter too
Lender requirements around genuine savings vary, and there is no single national rule. Some lenders want to see part of the deposit saved over time. Others focus on the overall picture. The treatment also depends on whether it’s savings, KiwiSaver, a gift, or a mix.
A gifted deposit can absolutely work. It generally needs a gifting letter confirming the money is a gift rather than a loan, and some lenders will also want to see a savings pattern alongside it. If a large sum arrived in your account recently, expect to be asked about it. That is a normal part of the process rather than suspicion.
Worth reading alongside this: changes to low-deposit lending rules and what changes with a 5% deposit.
Credit history and how your accounts look
Clients tend to worry about their credit score. In practice, assessors also read the bank statements closely.
They generally look across three to six months of transactions for patterns: dishonoured direct debits, accounts going into unarranged overdraft, or regular gambling activity. These won’t always show in a credit score. Even so, they can count against an application that otherwise looks strong.
Credit enquiries are recorded on your file and can be relevant, though they are easy to over-read. Several enquiries in a short period may prompt a lender to ask what happened, and they do not automatically indicate previous declines. People shop around, get quotes, or apply for unrelated credit. It is reasonable to expect the question, and reasonable to have an answer for it. That is a large part of why I suggest understanding the first decline before making a second application.
Arrears and defaults are more involved. How much weight a lender gives them depends on how recent they are, how large, whether they have been paid, and that lender’s own policy. There is no universal waiting period, and I would be cautious of anyone who quotes you one without looking at your file.
Background reading: how your credit score works in New Zealand, and Consumer Protection’s guidance on credit checks, scores and history.
You are entitled to request your own credit report from Centrix, Equifax or Experian (which took over illion). Checking it yourself does not affect your score the way a lender enquiry can, and it is worth doing before any new application.
What banks look for in your bank statements
This is the question I get asked most, usually after a bank has quoted a line from someone’s statements back to them.
The lending rules eased in July 2024, when the government removed the strict CCCFA affordability regulations. Banks no longer have to check every line of your spending the way they did in 2022. They can rely on what you tell them, or on a benchmark, as long as it’s reasonable. Most still ask for about three months of statements, but what they’re looking for has shifted. They care less about your coffee and more about what the statements show about your debts and how you handle money.
| What they see | Why it matters | What to do |
|---|---|---|
| Regular payments to a lender you didn’t mention | Undisclosed debt. Nothing loses a bank’s trust faster | Declare every debt upfront, even small ones |
| Afterpay, Laybuy and other buy now pay later | Counted as debt, and heavy use reads as cash-flow stress | Pay them off and close the accounts before you apply |
| Dishonoured payments or unarranged overdraft | Suggests you’re running short between pays | Keep a buffer so nothing bounces for three months |
| Regular gambling, including TAB and online casinos | Treated as a conduct risk, not just spending | Stop well before you apply, and tell me honestly |
| Large deposits with no explanation | The bank needs to know where money came from | Keep records of gifts, sales and transfers |
| Child support or money sent to family | An ongoing cost that comes off your surplus | Declare it. It’s usually fine if it fits |
| Spending well above the bank’s benchmark | They’ll use your real figure if it’s higher | Know your own numbers before the bank does |
Can spending alone get you declined?
Rarely on its own. One expensive month, a holiday or a wedding isn’t a reason to decline. What gets people declined is a pattern the bank can’t ignore: living in overdraft, bills bouncing, buy now pay later stacked up, or gambling. The other one is spending that’s simply higher than your income can carry once the test rate is applied.
The debt that costs more than it looks
Banks count credit cards by the limit, often at around 3% of the limit a month, whether you use the card or not. A $10,000 limit can mean $300 a month taken off your available income. At a 7% test rate over 30 years, that’s roughly $45,000 less you can borrow, for a card you might never touch. Car loans are counted by the repayment, so a short, expensive loan hurts more than its balance suggests. There’s a full breakdown in how credit cards, Afterpay and car loans affect what you can borrow.
A 90-day clean-up before you apply
- Download three months of statements for every account and read them the way a bank would.
- List every debt and every limit, including buy now pay later and any money owed to family.
- Close the cards and buy now pay later accounts you don’t need, and get written confirmation.
- Set up a buffer so no direct debit bounces, and stay out of unarranged overdraft.
- Stop any gambling transactions, including small ones.
- Write a short note on anything unusual, such as a bond refund, a car sale or a gift, so you have the answer ready.
Three clean months won’t fix every problem, but it fixes more than people expect, and it’s entirely in your control.

When your income is a different shape
Plenty of declines have less to do with how much you earn than with how the income arrives and how it can be evidenced.
If you are self-employed, many lenders look for two full financial years of accounts and assess taxable profit rather than drawings. An accountant who minimises your tax can, quite legitimately, lower the income a lender uses. In my experience, that gap is a common reason self-employed applications come in low.
A shorter trading history does not automatically push you to alternative documentation lending. Requirements vary between lenders. Some will accept a shorter history if you have prior experience in the field or an ongoing contract. Strong evidence also helps, such as GST returns, business banking and an accountant’s letter. Specialist and non-bank lending is another avenue, though it is not the only one and not always the right one.
Contractors, people on commission or overtime, and parents back from leave all face similar questions about proving income.

If a non-bank lender is suggested
Non-bank and specialist lenders assess some situations more flexibly than main banks. However, that flexibility usually means higher rates and extra fees. So weigh the total cost against the benefit of buying sooner.
If the plan involves refinancing to a main bank later, treat that as an intention rather than a certainty. It depends on your circumstances at the time and on lender policy then, neither of which can be guaranteed now. Before going down this path, agree a realistic exit strategy. That includes what happens if refinancing isn’t available when expected.

What to do in the next 30 days
Ask what you were assessed at
Ask your adviser or lender what borrowing figure the assessment produced and how it compared with what you needed. A figure gives you something to work with. Being told you did not qualify does not.
Request your own credit report
Available from Centrix, Equifax or Experian (which took over illion). Look for defaults you were unaware of, which do turn up, and for closed accounts still showing as open.
List every commitment with its repayment
The repayment rather than the balance, and for cards the limit. Then look at which reduction would do most for your serviceability. It is not always the largest debt.
Close facilities you no longer use, properly
Cancelling a card is not always the same as closing the account. Ask for written confirmation.
Tidy the next few months of statements
An assessor is likely to read them. Consistent conduct, no unarranged overdrafts, and a visible savings pattern all help.
Then apply once, to a lender whose policy fits
With the supporting evidence already assembled, rather than making several applications and hoping one lands.
Can a mortgage adviser help after a decline?
Often, yes, though it depends on what caused the decline, and it would be wrong to suggest an adviser can undo every one.
Where an adviser tends to add value is in the diagnosis. Lender policies differ, sometimes a lot. They vary on test rates, overtime, commission, self-employed income, deposit source and credit history. Knowing which lenders will view you favourably is most of the work. And it’s hard to do from the outside.
The other part is preparation. A decline sometimes comes down to how the application was presented rather than the underlying position, particularly where income is not straightforward. For example, full financial statements, a clear note about a one-off expense, or gift documents can all change the outcome.
What an adviser cannot do is change your income, remove an accurate default from your file, or override a lender’s credit policy. If buying isn’t achievable right now, it’s better to hear that with a plan. Finding out the expensive way at another lender helps no one.
It is also worth knowing that anyone giving you regulated financial advice in New Zealand must be operating under a licence issued by the Financial Markets Authority. The FMA has useful guidance on working with a financial adviser, including what to ask about fees and how an adviser is paid.
When a second opinion is reasonable
Ideally a decline comes with a figure and a next step. If you have not been given either, you have not really been given an answer yet.
Consider a second opinion if nobody told you what you were assessed at, or only one lender has seen your file. The same applies if your income is non-standard, or you were told no without being told what to change. Equally, if you have been given a clear figure and a plan with a timeframe, that may well be sound advice even though it is not the answer you wanted.
Where these rules actually come from
It helps to know which constraints are regulatory and which are the individual lender’s choice, because they behave differently.
- Reserve Bank rules. The LVR and DTI restrictions are set by the Reserve Bank and apply across registered banks. They are portfolio speed limits on the lender rather than eligibility rules about you.
- Lender credit policy. Test rates, living cost benchmarks, how credit card limits are assessed, genuine savings expectations and self-employed requirements are set by each lender. These vary, and they change.
- General market practice. Requesting bank statements, gifting letters and accountant confirmations is common across the market, though the specifics differ.
- Mortgage Sense experience. Where I have said something is common or is what I see most often, that is my observation from working with clients, not published data. I have tried to label it as such throughout.

Frequently asked questions
Lenders assess the repayment at a test rate above the advertised rate, and add estimated living costs and existing commitments. A strong rental history helps, and some lenders will consider it. But it doesn’t replace that test, because the test uses a higher repayment than you pay now.
There is no fixed waiting period. What matters is whether something has changed. If you have closed a credit card or cleared a loan, a new application may be reasonable within weeks. Where the issue was arrears or a default, the timeframe depends on how recent and how significant it was, and on the lender’s policy. Reapplying with nothing changed generally just adds another enquiry.
The decline itself is not recorded on your credit file, but the enquiry generally is, and it is visible to other lenders. Several enquiries in a short period may prompt questions, though they do not automatically mean you were declined. Checking your own credit report does not have the same effect as a lender enquiry.
Partly. A larger deposit means a smaller loan, which lowers both the required repayment and the DTI ratio, so it can help. What it does not do is increase your assessed income. Where income is the limiting factor, additional savings may not be enough on their own.
It is possible in many cases. Lender policies differ on many things, from test rates to self-employed income. So a decline at one bank reflects that lender’s policy, not the whole market. Understanding why the first application fell short helps direct the next one sensibly.
Generally yes. Most lenders assess against the limit rather than the balance, because the full limit could be drawn at any time. A card you clear monthly can still reduce your borrowing capacity, which is why reducing or closing unused limits is often one of the quicker adjustments available.
No. Six for owner-occupiers and seven for investors are thresholds, not absolute caps. Banks may write up to 20 percent of new owner-occupier lending above a DTI of 6, and up to 20 percent of new investor lending above 7. Lending above those levels does happen, within each bank’s allocation. Exemptions also apply, including new builds and Kāinga Ora lending.
It depends on what caused the decline. Non-bank lenders can be more flexible on credit history, self-employed income and unusual cases. However, they usually charge higher rates and extra fees. If you plan to refinance to a main bank later, treat that as a goal, not a certainty. Agree a realistic exit strategy before you commit.
Not necessarily, though you are entitled to specifics. Ask what figure you were assessed at, which lenders were considered, and what would need to change. A clear figure and a plan with a timeframe may well be sound advice even when it is not what you hoped to hear. If you cannot get either, seeking a second opinion is reasonable.
Not usually because of a single big month. Banks decline when your statements show a pattern, such as living in overdraft, bounced payments, stacked buy now pay later or regular gambling, or when your spending is higher than your income can support at the test rate.
Yes. Buy now pay later has been regulated as credit since September 2024, and banks count it as debt. Some make closing the accounts a condition of the loan.
Usually about three months for every account you use, including savings and credit cards. Self-employed borrowers may be asked for business statements too.
Regular gambling is one of the things banks look for in statements and it can lead to a decline, even when the amounts are small. If it’s in your recent history, talk to an adviser before you apply.
