What Banks Check Before Giving Pre-Approval
A pre-approval is based on how the lender assesses your overall position. This usually includes your income, expenses, existing debt, deposit, bank statements and whether the loan looks affordable under the bank's lending criteria.
The assessment is not only about how much you earn. Lenders also look at how reliable your income is, what regular commitments you already have, how your accounts are managed, and whether your deposit can be clearly verified.

Do Spending Habits Affect Mortgage Approval?
Sometimes. Lenders don't expect borrowers to be perfect, but they do want to understand how accounts are being managed and whether spending patterns are likely to affect future affordability.
Most applicants are in a better position than they think. The key is understanding what lenders may ask questions about before the application is submitted.

Common Reasons Pre-Approvals Are Delayed
Most delays occur because the lender needs additional information. Providing complete documents and clear explanations from the start can help keep the process moving smoothly.
Missing Documents
Incomplete income evidence, missing statements or outstanding identification documents are one of the most common causes of delays.
Large Unexplained Transactions
Significant deposits, transfers or unusual account activity may require further explanation before the lender can complete their assessment.
Deposit Evidence
Lenders need to understand where deposit funds are coming from, whether that's savings, KiwiSaver, gifted funds or sale proceeds.
Recent Changes
Recent job changes, new lending, increased credit limits or significant financial changes can lead to additional questions.
Bank Statement Issues
Screenshots, incomplete PDFs, missing pages or statement periods that don't cover the requested timeframe often need replacing.
Additional Lender Questions
Sometimes a lender simply requires clarification around income, expenses, account conduct or supporting documents before making a decision.
Adviser Tip
Most delays can be avoided by supplying complete documents upfront and responding quickly if additional information is requested.
