Mortgage guide

How a mortgage application works in NZ

A home loan application follows a fairly standard path in New Zealand: get approval in principle, gather your documents, have the property valued, pass the full credit check, and settle on the day. It looks complicated from the outside because every step has its own paperwork, but it is really a line of gates you pass in order.

Before you apply, the number you need to know is how much you can realistically borrow. That is worked out from your income, spending, debts and current rates, and our guide to borrowing power explains how, or you can get a quick estimate from the borrowing power calculator. Start there so you shop in a realistic range.

Pre-approval: the shopping pass

Most people begin with pre-approval, sometimes called approval in principle or a conditional approval. You tell a lender your income, spending and debts, and it gives a conditional yes up to a figure and a term. That figure is what you can comfortably offer on a house, and it makes you a stronger buyer because sellers know you are already vetted.

Be clear on what pre-approval is not. It is a yes based on the information you provide, not a guarantee of a specific loan at a specific rate. The final approval still depends on the checks that follow and on the property you choose. In short, it is a budget-setting tool, not a done deal.

The documents you will need

Lenders ask for a fairly predictable set, so gather it before you apply and the whole process moves faster:

Be upfront. A lender runs a credit check and will find debts you did not mention, and hiding them hurts your credibility more than the debt itself. Clean, consistent statements and honest answers are the fastest route through this step.

The property valuation

Once you have found a place and your offer is accepted, the lender arranges a valuation to confirm the purchase price is reasonable and the property is suitable security for the loan. A valuer inspects the home and reports on its location, condition and how the price compares with similar recent sales in the area.

This matters more than most people realise, because the bank lends against the valuation, not necessarily the price you agreed to pay. If the property values lower than your offer, your loan-to-value ratio changes and you may need a bigger deposit to make up the gap. Our guide to buying your first home covers the deposit and cost planning side of this in full.

Full credit approval and the fine print

With the valuation done, the lender runs the full credit check and pulls everything together: your file, the property, the loan amount, the rate and the term. If it is satisfied, it issues a formal offer. Do not skim that letter. It sets the conditions you must meet before the funds release, such as anything specific to the property, your income, or the source of your deposit, and it locks in the rate, the fees and the term.

Turnaround times and the exact checks vary between lenders, and a broker can help you compare offers, but the steps are largely the same wherever you apply. The mortgage repayment calculator is useful while you weigh different rates and terms before you commit.

Settlement day

Settlement is the day ownership transfers to you and the lender releases the funds. Your lawyer or conveyancer handles the process: the seller's legal team confirms the property details, the bank releases the loan, and the money changes hands. When everything clears, you get the keys, and your first mortgage repayment starts on the agreed schedule.

After settlement your mortgage is a live account. Extra repayments and an offset account can cut the interest you pay, and our guide to offset accounts explains when that beats simple extra payments, with an offset and extra repayment calculator to model it.

The point

Pre-approval tells you what you can afford to offer. Your documents and the credit check verify who you are. The valuation fixes how much the lender will advance against the property. Settlement hands over the keys. Keep the process linear, gather the paperwork early, and confirm current timeframes and fees with your lender, because they change.

Common questions

Mortgage applications: asked and answered

Is pre-approval the same as a guaranteed loan?

No. Pre-approval is a conditional yes based on the information you provide about your income, spending and debts, and it tells you a realistic borrowing figure for house hunting. The final loan is only issued after the full credit check, a valuation of the specific property, and the conditions in the formal offer are met.

What documents do I need to apply for a home loan?

Broadly, proof of identity, proof of income such as recent pay slips or past earnings for self-employed borrowers, your regular bank statements showing spending, evidence of any existing debts, and proof of your deposit and where it came from. Having these ready makes the process faster.

What happens at a property valuation?

The lender arranges a valuer to inspect the property and report on its location, condition, and how the accepted price compares with similar recent sales. The bank lends against the valuation, not necessarily the price you agreed, so a low valuation can mean you need a bigger deposit.

When does the lender hand over the money?

The funds release on settlement day, when ownership of the property transfers to you. Your lawyer or conveyancer handles the transfer, the lender releases the loan, and once everything clears you receive the keys and your first repayment starts on the agreed schedule.
