Tip: close to the limit on borrowing power? A broker can often lift servicing by trimming card limits, consolidating small debts, or using a split-borrower structure that fits lender policy better.
To qualify, you’ll need stable income, a deposit of at least 10–20%, and clean account conduct over the past few months. Lenders check your income, debts, spending habits, and credit score. If you’re using KiwiSaver or a First Home Grant, have those letters ready before applying — your mortgage broker can coordinate everything.
Most banks will ask for:
Photo ID and proof of address
Recent payslips or financial statements (if self-employed)
Last three months of bank statements
Details of loans, credit cards, and savings
KiwiSaver or grant confirmation letters
Providing full documentation upfront helps speed up approval and shows lenders you’re organised.
Most New Zealand pre-approvals last 60 to 90 days, depending on the lender. If your search takes longer, your broker can usually refresh or extend it with updated payslips and statements — a quick process if nothing major in your finances has changed.
Pre-approval confirms how much you can borrow based on your financial position, but it’s still conditional. Full approval happens once you’ve found a property, and the lender has checked the title, valuation, and insurance. Pre-approval gives you buying power — full approval seals the deal.
