A mortgage is usually declined because the lender believes the complete application does not meet its affordability, risk or policy requirements. One part of the application may look strong, but several smaller issues can combine to create a higher-risk result.
If you have had a mortgage application declined, this page explains why a home loan application may be declined in New Zealand and the most common factors that may have concerned the lender.
Understanding the real reason for the decline is often the most important first step, because it shows whether the problem can be addressed now, requires a different lender or structure, or simply needs more time. That diagnosis should come before another application.

Although these categories are explained separately below, many declined applications involve more than one issue at the same time. Before looking at each factor in more detail, many borrowers recognise themselves in one or more of the situations below.
A strong income does not always produce enough borrowing capacity. Existing commitments such as a car loan, credit-card limits or Buy Now Pay Later accounts can reduce the headroom available under the lender’s servicing test, even when the borrower is managing those commitments comfortably.
It may have contributed. Lenders often consider the pattern, timing and explanation behind late payments, defaults and recent credit enquiries rather than looking at one event in isolation. An older resolved event may be assessed differently from several recent issues or an ongoing pattern.
A borrower may have saved a deposit that looks strong on paper, but the bank does not assess the deposit in isolation. It also considers the property, loan purpose, source of funds and the borrower’s complete position. A deposit that may be acceptable for one property may not be sufficient for another.
Apartments, small dwellings, leasehold or mixed-use property, rural or lifestyle property, and buildings with condition or compliance concerns can reduce the available lender options or change the required equity. There is no universal property-size or deposit threshold that applies to every application.
Income level is only part of the assessment. A lender also needs to understand whether the income is stable, repeatable and supported by suitable evidence. A recent move into self-employment, variable monthly income or a recent job change may therefore affect the decision even when current earnings are strong.
In our experience, this is the area that often surprises borrowers most. Recent statements may show frequent overdrafts, dishonours, missed direct debits, short-term borrowing, gambling or spending that does not align with the budget provided in the application.
These patterns do not automatically decide every application, but they can influence how the lender assesses affordability, reliability and whether the proposed mortgage appears sustainable
Affordability is one of the most common reasons borrowers misunderstand a mortgage decline. The lender’s servicing calculation may produce a very different result from the borrower’s own household budget.
Many people look at their income, subtract their current living expenses and assume the remaining amount should be available for mortgage repayments. Unfortunately, that isn’t how lenders assess affordability.
Angela Downie, Financial Adviser, Platinum Mortgages explains:
“Most banks and non bank lenders don’t calculate repayments using today’s interest rate. Instead, they use a higher test or stress rate to make sure borrowers could still afford the loan if interest rates increased in the future. They also use their own minimum living-expense benchmarks, which are often higher than what a household is actually spending today, and allow for future homeownership costs such as rates and insurance. Depending on the lender, affordability may also take into account the borrower’s overall debt compared with their income.”
Understanding how each lender assesses affordability is often the first step towards understanding why an application was declined and what can be done next.
The sections below explain how each main factor can affect the lender decision:
A lender does not assess affordability in isolation. It considers income stability, existing commitments, credit history, deposit or equity, the property and whether the complete application fits its lending policy.
Incomplete, inconsistent or undisclosed information can also affect the decision, particularly where liabilities, expenses, income changes or important property information emerge during assessment.
The proposed mortgage must remain affordable after the lender includes normal living costs, existing commitments and its own servicing assumptions. A borrower may manage today’s repayments comfortably but still fall short under the lender’s test.
Existing repayments and available credit limits can reduce borrowing capacity. Some lenders also assess unused limits because the facility could be drawn later. For the detailed treatment of ordinary debt and servicing, read how existing debt affects mortgage approval.
Lenders consider the type, age, frequency and explanation of past missed payments, defaults, arrears and recent credit enquiries shown in the applicant’s credit or account history. The timing and pattern of an issue also matter. A single older event may be assessed differently from an ongoing pattern. Before applying again, it can be worthwhile obtaining a copy of your credit report so you understand exactly what lenders may see and can correct any unexpected issues before another application is submitted. For credit-specific guidance, read about mortgage options with bad credit.
The deposit is assessed together with the property, purpose and complete application. Apartments, leasehold titles, rural or lifestyle property, mixed-use property, small dwellings, condition issues or incomplete compliance documentation can reduce the number of available lenders or change the required equity.
There is no universal apartment-size or deposit threshold that applies to every application. Lender policies differ and can change, so the property and available equity need to be assessed together with the borrower’s complete position.
The property itself can cause a decline even where the borrower’s income and deposit otherwise appear sound.
The lender may also need to verify where the deposit came from and whether any gifted, borrowed or conditional funds meet its policy.
Lenders need to understand how stable and well-supported the income is before they can assess whether it is likely to continue. Recently self-employed borrowers may need alternative documents or more trading history. If you’ve been self-employed for less than two years, read our self employed evidence guide to understand the documents lenders may accept and the pathways that may be available.
Recent statements can show overdrafts, dishonours, missed direct debits, frequent short-term borrowing, gambling or spending that does not align with the declared budget. These patterns do not automatically decide every application, but they can change the lender’s view of affordability and reliability.
Sometimes the loan is declined because one lender does not accept the income type, property, deposit source or structure. That does not prove another lender will approve. It means the specific policy issue should be understood before another application is submitted.
“When I review a declined application, one thing I regularly discover is that the underlying issue isn’t always what the borrower has been told. Sometimes it’s something as simple as a credit issue they weren’t even aware of, or an application that wasn’t matched to the right lender from the outset.
That’s why I always carry out a thorough pre-assessment before recommending a lender. I review a client’s credit profile and overall circumstances first, so I have a good understanding of which lenders are likely to be the best fit. Taking the time to do this upfront can help avoid unnecessary declines and gives my clients a much clearer idea of their options before another application is submitted.”
– Angela Downie
A careful review of the complete application can identify the real reason for the decline and help avoid repeating the same problem with another lender. It can then show whether a different lender, a revised structure or additional preparation offers the stronger next step.

Before submitting another mortgage application, it’s worth understanding whether the previous decline was caused by a lender policy, the structure of the application or something that can be improved.
Angela says: “Before someone applies again, the biggest mistake I encourage them to avoid is assuming every lender assesses applications the same way.
Each bank and non bank lender has its own lending criteria, and what one lender declines, another may be willing to consider.
For example, some lenders won’t include overtime income at all, while others may accept all of it if it’s consistent and well supported. The same applies to self-employment, casual income, bonuses and many other parts of an application.
Rather than submitting the same application to multiple lenders, I tailor the application to the lender that’s most likely to view it favourably based on the client’s income, credit profile and overall circumstances.”
Need to decide what to do next?
If your application has already been declined, the next step should be based on the reason for the decline rather than simply trying another lender.
