What Documents Do You Need for a Mortgage Application?

One of the most common causes of delay in the mortgage application process is incomplete documentation. Lenders need a clear picture of your financial situation before they can make a lending decision, and gathering the right paperwork upfront can significantly speed up the process. Under the Credit Contracts and Consumer Finance Act (CCCFA), lenders are required to make responsible lending assessments, which means they need thorough evidence of your income and expenses. Knowing what to prepare before you apply puts you in a much stronger position from the start.

Proof of Identity

All lenders require identity verification as part of their anti-money laundering obligations. You will typically need to provide a current New Zealand passport or driver's licence, along with proof of your address such as a recent utility bill or bank statement. If you are not a New Zealand citizen or permanent resident, you will also need to provide evidence of your visa status, as this affects your eligibility to purchase property and take on New Zealand mortgage lending.

Income Verification

For salaried employees, most lenders will want to see recent payslips, typically the last two or three, along with a letter from your employer confirming your employment status, salary, and tenure. They will also want to review three to six months of bank statements to verify that your stated income is being received consistently. If you receive bonuses, commission, or overtime, lenders will usually want evidence that these payments are regular and reliable before including them in the assessment.

Self-employed borrowers face a more thorough income assessment. Lenders typically require two years of financial statements prepared by a chartered accountant, two years of personal tax returns, and your most recent GST returns if applicable. Some lenders will also ask for an accountant's certificate confirming that your business is ongoing and financially sound. If you have been self-employed for less than two years, lending options may be more limited, though some lenders will consider applications with supporting evidence of prior employment in the same field.

Expenses and Existing Debt

Under the CCCFA, lenders are required to assess your ongoing expenses thoroughly. Bank statements covering the last three to six months are the primary tool for this. Lenders will look at regular outgoings including rent, utilities, subscriptions, credit card repayments, personal loan repayments, hire purchase commitments, and any other regular financial obligations. It is important that your bank statements accurately reflect your typical spending, as lenders will use them to form a view of your committed and discretionary expenses.

Deposit and Savings Evidence

Lenders will want to see evidence that your deposit funds are genuine savings or otherwise legitimate in origin. Bank statements showing the accumulation of savings over time are ideal. If part of your deposit is coming from a KiwiSaver withdrawal, your lender will need confirmation of your KiwiSaver balance and, where applicable, a First Home Grant approval letter. Gifted deposits from family members are accepted by many lenders but typically require a signed gift letter confirming the funds are not a loan and do not need to be repaid.

Property Documents

Once you have a specific property in mind, your lender will also need relevant property documentation. For an existing home, this includes the signed sale and purchase agreement. For a new build, the building contract and council consent documentation will be required. A registered valuation is typically organised by the lender but may also be requested at your cost depending on the lender and the circumstances.
