Home Buying · 12 October 2026 · Written by Arapeta Albert, Financial Adviser (FSP433026)
A home loan is approved in stages, not once, and each stage waits on something different. Here is what each one needs, who actually sets the deadline, and where the time usually goes.

With a complete application, a lender's decision commonly comes back within a few working days. It takes longer when information is missing, when income or the property is unusual, or when lenders are busy. Timelines vary by lender and by application, so no single figure is reliable.
The bigger reason there is no single figure is that a home loan is not approved once. A purchase carries three separate clocks, and only the first two belong to the lender.
The lender checks income, spending, debts, credit history and deposit, and sets a limit. It is conditional and it expires. Settled, the Real Estate Authority's home buying guide, says conditional pre-approval usually lasts for 3 months (Source: Settled.govt.nz).
Once there is a property, the lender looks at the signed agreement and the home itself, sometimes with a valuation. This is the step that lets a buyer confirm finance and go unconditional.
Loan documents are signed with a lawyer or conveyancer, insurance is arranged, and the lender's remaining conditions are met. Funds move on settlement day, a date set in the agreement.
Most of the weeks in a purchase are spent searching and waiting for settlement. The lender's decisions are short stretches inside that. What makes them feel long is that the second one runs against a deadline.
Because a pre-approval is given before the lender has seen what it is lending against. A home loan is secured over a specific property, and that property does not exist in the application yet.
Settled puts it plainly: even with conditional pre-approval, most banks and lenders will ask for information about the property before confirming the home loan, which is why an agreement may have to be conditional on finance. That information can include a copy of the signed sale and purchase agreement and a valuation, and the lender is likely to want proof of property insurance before settlement.
So the word "approved" on a pre-approval letter and the word "approved" on a confirmed loan offer mean different things. The first says the lender is comfortable with the borrower up to a limit. The second says it is comfortable with this borrower buying this property at this price. How the first stage works, and what documents it needs, is covered in our guide to mortgage pre-approval in NZ.
The buyer and the seller do, not the lender. A conditional offer says how many working days the buyer has to confirm finance, and that number is written into the sale and purchase agreement when the offer is made. Settled describes a conditional agreement as one with conditions that must be met by a specified date.
This is the part most timelines leave out. The lender is not a party to that agreement and is not bound by its date. The buyer chooses the deadline first, usually before the lender has seen the property, and the lender's process then has to fit inside it. Three things follow.
There is no fixed finance period. A seller with other interested buyers may push for fewer working days, and a buyer whose lender needs a valuation needs enough days for one to be booked, done and read.
The agreement defines it. Weekends and public holidays do not count, and nor does a stretch over Christmas and New Year: the Property Law Act 2007 leaves out 25 December to 2 January, and an agreement can set a longer break. The same number of working days can cover very different stretches of the calendar, so it is worth confirming the dates in yours with your lawyer or conveyancer.
If the lender has not finished by the date, an extension is a change to the agreement, and the seller has to agree to it. Settled notes that when a condition is not met in time the seller may be entitled to cancel, so that conversation goes better before the date than on it.
A finance condition is also not a free exit. Settled notes that some agreements require a buyer who cannot satisfy the condition to supply evidence from the bank that finance was declined, and that without it the buyer may still be required to proceed with the sale.
How much room there is to ask for more days depends on the market. Auckland's largest real estate agency ended September with its highest stock of homes for sale for that month since 2008 (Source: interest.co.nz, 5 October 2026). When buyers have plenty to choose from, a workable finance period is an easier thing to ask for than it is in a rising market.
Mostly things that sit outside the decision itself. A lender can only assess what it has been given, and each request for more information puts the file back in a queue.
Payslips and bank statements age. A pre-approval that has lapsed, or is close to it, generally needs current documents before the lender will confirm anything.
Where the lender wants one, it has to be ordered, the property visited and the report written and read. None of that starts until someone orders it.
A new job, a new car loan, a smaller deposit or a different kind of property than the pre-approval assumed can each mean a fresh assessment, not a quick confirmation.
A KiwiSaver first home withdrawal runs on the provider's notice period, not the lender's, and insurance has to be in place before settlement. Our guide to the KiwiSaver first home withdrawal covers the timing.
Income that takes more reading, such as self-employed income, also takes longer to assess. So does a busy period: when many people apply at once, every lender's queue grows.
What can be shortened is the waiting around the decision. A complete application the first time, current documents, a valuation ordered early where one is likely, and a lawyer who sees the agreement before it is signed all take days out without asking the lender to move any faster.
The order reverses. A winning auction bid is unconditional, so there is no finance condition to work inside. Everything the lender needs to know about the property has to be settled before auction day, on a home the buyer may not win.
That makes an auction the clearest test of which stage a buyer is at. A pre-approval limit says what the lender thinks of the borrower. It does not say the lender has accepted that particular property, and at an auction there is no later date on which to find out.

With a complete application, a decision commonly comes back within a few working days. It takes longer if the lender has to ask for more information, if income is complex, or if lenders are busy. Timelines vary by lender and by application.
Settled, the Real Estate Authority's home buying guide, says conditional pre-approval usually lasts for 3 months. The period is set by each lender, so the date on the approval letter is the one that counts. A lapsed pre-approval can generally be renewed with current documents, and it is reassessed when it is.
It depends on what the lender needs to see about the property. A signed sale and purchase agreement is the starting point, and a valuation adds time where one is required. With current documents and a straightforward property, confirmation can be quick. Where circumstances have changed since the pre-approval, it is closer to a fresh assessment.
There is no standard number. It is agreed between buyer and seller and written into the sale and purchase agreement. What suits depends on what the lender will need, in particular whether a valuation is required, and on how the agreement defines a working day. A lawyer or conveyancer and a Financial Adviser can help size it before the offer is signed.
The agreement decides. More time needs the seller's agreement, arranged through the lawyers. Settled notes that some agreements require a buyer who cannot satisfy the finance condition to supply evidence from the bank that finance was declined, and that without it the buyer may still be required to proceed. It is a conversation to have with your lawyer before the date arrives.
The lender's assessment is the same either way, and timing varies by lender and application. What an adviser can change is the preparation: choosing a lender whose criteria fit, and submitting a complete application the first time so fewer questions come back.
