Bank vs Non-Bank Credit Criteria: Key Differences for Brokers
A broker's value is partly determined by the breadth of their lender panel and their ability to identify the right home for each client's application. The distinction between bank and non-bank lenders goes well beyond interest rates - the differences in credit policy, acceptable income types, property criteria, and risk appetite can mean that an application declined by every mainstream bank is perfectly serviceable for a non-bank lender. At Chaperone, we work with brokers across the full lender spectrum and see firsthand how this knowledge shapes outcomes for clients who might otherwise believe they have no options.
How Bank Credit Criteria Are Set
Registered banks in New Zealand operate under the prudential oversight of the Reserve Bank of New Zealand (RBNZ), which means their lending policies must reflect capital adequacy requirements, LVR restrictions, and increasingly, DTI (debt-to-income) ratio limits. Banks also apply internal credit scoring models, standardised income verification requirements, and serviceability calculators that are designed to stress-test borrowers against rate increases. These frameworks are broadly consistent across banks, which is why clients who do not fit the standard profile tend to receive consistent declines across the banking sector rather than finding one bank that is more accommodating. Banks are generally conservative by design - the RBNZ framework is intended to limit systemic risk, which naturally restricts flexibility at the margins.
Where Non-Bank Lenders Differ
Non-bank lenders in New Zealand are not registered banks and are not subject to the same RBNZ prudential requirements, which gives them more flexibility in their credit policies. They can set their own LVR limits, apply different servicing calculations, and make more nuanced assessments of non-standard income, credit history, and property types. This does not mean non-bank lenders take unlimited risk - they price their loans to reflect the risk profile of their borrower base, which is why non-bank interest rates are typically higher than bank rates. The trade-off for the borrower is access to credit they could not otherwise obtain, at a cost that reflects the additional risk the lender is carrying. Understanding this trade-off is essential for having an honest conversation with clients about non-bank options.
Income Assessment Differences
One of the most practically significant differences between bank and non-bank credit criteria is how each handles non-standard income. Banks typically require two years of financial accounts for self-employed borrowers and apply a conservative shading to variable income components such as bonuses, commissions, or trust distributions. Non-bank lenders may be willing to accept shorter income histories, use gross revenue rather than net profit for assessment in some circumstances, or take a more flexible view of income sources that banks would not recognise at all. For self-employed clients, contractors, or those with complex income structures, identifying a lender whose policy genuinely accommodates their situation is a higher-value service than simply submitting to the most recognisable name on the panel.
Credit History and Adverse Events
Banks generally apply strict rules around adverse credit history. A default within the past two to five years will often result in an automatic decline at a mainstream bank, regardless of the surrounding circumstances. Non-bank lenders typically take a more case-by-case approach, considering the age and size of the default, whether it has been paid, and the overall pattern of financial behaviour rather than applying a binary rule. This means that clients with minor historic credit issues - a paid default from several years ago, a brief period of arrears, or a small judgment that has since been settled - may have genuine options with non-bank lenders that would be closed to them at a bank. Assessing these cases accurately requires knowing the specific policies of the non-bank lenders on your panel, not just a general sense that they are more flexible.
Property Criteria and Unusual Security
Non-bank lenders can also be more accommodating with unusual property types that banks decline to lend against. Small apartments below minimum square metre thresholds, properties in certain high-density areas, rural residential properties on larger sections, and properties with mixed residential and commercial use can all fall outside bank lending criteria but within the acceptable security range for some non-bank lenders. Knowing which lenders on your panel will consider which property types is essential for avoiding wasted submissions. A pre-submission conversation with a non-bank BDM to confirm that a specific property meets their security criteria before preparing a full application is time well spent.
Using Non-Bank Lending Strategically
The most effective use of non-bank lenders is often as a deliberate interim step rather than a permanent solution. A client who borrows through a non-bank lender at a higher rate, establishes a clean repayment record over one to two years, and then refinances to a bank at a lower rate has used the non-bank option strategically and well. Framing it this way to clients - as a bridge to mainstream lending rather than a consolation prize - changes the conversation from accepting a worse deal to executing a sensible two-stage plan. At Chaperone, we see brokers who understand the full lender spectrum and communicate it clearly to clients consistently deliver better outcomes and earn more referrals as a result.
