Two buyers want your house. It’s the best problem a seller can have, and it’s also the moment a private sale most needs structure, because a handful of rules is all that separates a fair contest from a shambles. New Zealand already has the playbook: settled.govt.nz, the Real Estate Authority’s consumer site, describes how a multi-offer process in NZ works when agents run one, and the same rules work just as well when the owner is in charge.
A fair multi-offer process in NZ rests on three commitments: every interested buyer is told a multi-offer situation exists, everyone gets the same deadline and the same information, and each buyer puts forward one best-and-final offer in writing through the lawyers. No buyer’s number is ever revealed to another. Agents run it this way because it’s fair and it holds up; you can run it the same way.
What a multi-offer process in NZ normally looks like
settled.govt.nz’s multi-offer guidance is written for buyers facing one, which makes it a useful mirror for the seller running one. The shape is consistent. When more than one buyer wants to make an offer, all of them are told they’re in a multi-offer situation. Each is invited to put forward a single, final offer by a set time, knowing they may not get another chance. The offers are then considered together, and the seller accepts one, negotiates with one, or declines the lot.
The logic is simple. Because the competition is real and disclosed, buyers put their honest position on paper instead of testing you with small increments. And because everyone knew the rules, the buyer who succeeds can’t be accused of anything, and the buyers who miss out were beaten fairly.
Running it without an agent changes the coordinator and nothing else: you deliver the messages, and your lawyer handles the paperwork.
Tell everyone, and tell them the same thing
The process starts the moment a second buyer signals a real intention to offer. From then on, every interested buyer gets the same message: a multi-offer situation exists, offers are due by this date and time, offers should be their best, in writing, through their lawyer.
Put it in email so a record exists. Then match the information as carefully as the deadline: whatever documents you’re providing (the title, a LIM, a building report if you’ve commissioned one, the draft agreement from your lawyer) go to every buyer at the same time.
Give the deadline enough room for buyers to act properly, too. Each of them needs time to talk to their bank and have the agreement reviewed by their own lawyer, so a deadline set days out, rather than hours, gets you considered offers instead of panicked ones. Even-handedness protects you as much as them. An accepted offer from a buyer who had everything the others had is an offer nobody can later claim was won on a tilted table.
Never shop one buyer’s number to another
The tempting shortcut is to ring buyer B and say “I’ve got $850,000, can you do better?” Agents don’t run multi-offers that way, and you shouldn’t either, for two reasons.
The first is that it wrecks the incentive that makes the process work. Sealed best-and-finals exist because they push each buyer to their own honest ceiling. Start leaking numbers and you’ve converted a final-offer contest into an auction without an auctioneer, where buyers inch up in $1,000 steps and the one who feels played walks away.
The second reason is your own safety. What you tell buyers carries legal weight, and if a number you quote is exaggerated, misremembered or invented, you’ve misled a buyer in a way that can unwind a sale or end in a compensation claim. The clean rule costs you nothing: reveal the existence of competition, never its size. “There are other offers, so put forward your best” is honest pressure. Anything more specific is a risk you don’t need.
Best and final, in writing, through the lawyers
A number floated at the kitchen bench is conversation. An offer is a signed sale and purchase agreement, which is the standard settled.govt.nz applies on the selling side too, and in a multi-offer each buyer’s signed agreement should come through their lawyer to yours by the deadline.
Then comes the weighing, and it’s yours alone. Price is one line on the front page; the deposit, the settlement date and the conditions fill the rest, and they differ. An unconditional offer at one number and a heavily conditioned offer at a higher number are different products. Your lawyer’s job is to make sure you understand exactly what each agreement says before you decide; deciding is your job, and no one else’s. We’ve covered how the conditions themselves work in our conditional-offers guide.
If no offer clears your reserve, declining all of them is a legitimate outcome of a multi-offer. So is going back to negotiate with one buyer once the process has run its course.
The deadline sale is this process, pre-packaged
If competition looks likely before you even list, you can build the multi-offer structure in from day one. A deadline sale, one of the standard methods on settled.govt.nz’s methods-of-sale page, advertises the property without a price and invites all offers by a set date. Same deadline for everyone, by design; the rules above just describe what happens when the offers arrive. Trade Me supports deadline-sale listings from private sellers (Trade Me Property, checked July 2026).
An advertised price with offers welcome works too; you’ll be improvising the deadline if a second buyer appears mid-campaign. The deadline sale saves the improvisation.
If you’re selling with Celby, the leads board keeps every interested buyer and conversation in one place, which is most of the admin of a multi-offer. A dollar figure noted there is a reference for you; a real offer only exists in writing, through the lawyers. And the conveyancing lawyer included in our $8,000 flat fee is the one holding the paperwork on deadline day.
Fairness in a multi-offer isn’t generosity. It’s what keeps the winning buyer confident enough to stay won.
