Last reviewed: 21 September 2026. Condition periods, council timeframes and lender policies vary, so treat the timings here as typical rather than fixed and confirm dates with your lawyer.

Short answer

Your offer being accepted starts a clock, commonly ten working days, in which you have to satisfy every condition written into the agreement. Nothing is binding yet. Miss the date without an extension and the agreement can be cancelled. Confirm everything and you go unconditional, at which point you are committed and the deposit is payable.

Ten working days is not two weeks. With a public holiday in the middle it can stretch past a fortnight on the calendar. People book a builders report for day nine and find the inspector is not free until day fourteen.

Ten working days sounds like plenty until four things have to happen at once.

Run every condition at once

The most common mistake is doing conditions in sequence. Someone waits for the builders report to come back clean before bothering the bank, loses four days, then spends the last afternoon calling a lawyer who is already in a meeting.

They run in parallel. All of them, the morning after the offer is accepted. Your lawyer and your adviser both need the signed agreement on day zero, not a photo of the first page.

A typical ten working day condition period and what should be happening on each day
DayWhat should be happening
0Offer accepted. Signed agreement goes to your adviser and your lawyer the same day.
1Building inspection booked. LIM ordered. Adviser submits the full application with the property attached.
2 to 4Lawyer reviews title, LIM and the agreement. Inspector attends. Insurance cover confirmed as available.
5 to 7Building report back. Bank approves, or comes back with conditions of its own. Valuation ordered if the lender wants one.
8 to 9Anything unresolved goes back to the agent now. Extension requested in writing if you need one.
10Lawyer confirms conditions in writing. You are unconditional and the deposit is payable.

Condition periods are counted in working days, so weekends and public holidays do not count. Write the actual calendar date down and confirm it with your lawyer, because this is where most of the panic comes from.

Run sequentially and you run out of days. Run in parallel and the same work fits.

What each condition actually is

Finance. Your pre-approval is not finance approval on this house. The bank approved you. It has not approved this property. A pre-approval can be live and correct and the bank can still decline a particular place because of the title, the size, the condition, or a valuation that comes back short.

Builders report. Usually worded as a report satisfactory to the purchaser, which gives you room to walk if it comes back badly. The wording matters, and your lawyer should see it before you sign rather than after.

LIM. The council file on the property. Consents, drainage, hazards, notices. Councils take several working days in most districts and longer in some, which is exactly why this gets ordered on day one.

Title and solicitor’s approval. Your lawyer reads the title, the easements, the covenants, and the lease documents if it is cross-lease or unit title. If something on the title is a problem, this is the condition that lets you out.

Insurance. Overlooked until the bank asks for a certificate. If the house has had a fire, sits in a flood zone, is partly unconsented, or is pre-1940 with original wiring, cover is not automatic and it can take longer than you expect.

Can I pull out before unconditional?

Only through a condition, and only on the grounds that condition gives you. Changing your mind is not a finance decline. If you cancel without a proper basis the vendor can pursue you, and losing the deposit is the least of it.

Worth saying plainly, because a lot of buyers treat the condition period as a free trial. It is not. It is a window to check specific things, and each condition only lets you exit for its own reason.

Going unconditional means the agreement is binding. Do not confirm a condition you have not actually satisfied, even under pressure from an agent, and never confirm finance before your adviser has written approval on that address.


Extensions are normal. Silence is not.

Councils run late. Inspectors get booked out. Banks ask for one more payslip on day eight. Extensions get granted all the time, and most vendors would rather grant one than watch the deal collapse.

What kills agreements is going quiet. If something is not going to land, the request goes through your lawyer to the vendor’s lawyer, in writing, before the deadline. Not at ten to five on the day.

The worst version of this is a buyer who cannot reach their own lawyer on the afternoon of the deadline and has no idea whether they still have the house. If you cannot get hold of your lawyer, call the agent and get the extension moving rather than waiting for a callback.

One line in the whole process is irreversible. This is it.

Conditions the bank adds after approval

This one catches people. The bank approves the loan and then attaches its own conditions to settlement, separate from the ones in your agreement. The usual ones: close a named credit card, provide a boarder declaration, show evidence a debt has been repaid, supply the insurance certificate, accept a registered valuation.

None of those are refusals. They are things to work through. But they have to clear before drawdown, and the ones involving somebody else take longer than the ones involving you.

Worth reading alongside this: buying at auction in NZ, tenders and multi-offers, how much can I borrow, using KiwiSaver for your first home, and what to do if your home loan is declined.


Frequently asked questions

Commonly ten working days, though anything from five to twenty gets written in. It is negotiable when you make the offer, so if you know your bank is slow, ask for longer up front rather than requesting an extension later.

Working days. Weekends and public holidays do not count, which is why the actual calendar date is the thing to write down and confirm with your lawyer.

Yes. It is commonly 10 percent, payable into the agent’s trust account on confirmation. If your deposit is coming from KiwiSaver, that money is generally not available until settlement, so you need separate cash for this part.

Yes. Tell your adviser before you make an offer rather than after. Renewing usually needs fresh payslips and statements, and it takes days rather than minutes.

Not on your own. Both parties have to agree to a variation, so the conditions need to be right before you sign.

The deposit is payable, the agreement is binding, and the next date that matters is settlement. Your lawyer takes over most of the running from there.
