For a lot of sellers, "auction" is the word that raises the heart rate. It sounds fast, public and a little out of your control. In reality, an auction is one of the most structured and transparent ways to sell a home in New Zealand. It runs on a clear timeline, every stage has a purpose, and at no point are you handing over the decisions that matter. This is a process we navigate together — and we make each call on the facts the campaign is actually producing, not on hope. Here's exactly how it unfolds, week by week.
First, is auction even the right method for you?
Auction is one of several ways to sell — alongside deadline sale, price by negotiation and an advertised asking price. It isn't automatically the right fit for every property or every owner, and I'll never push you toward it because it suits me.
Auction tends to work best when there is genuine buyer competition to be had: a home with broad appeal, a sought-after location, or a property where the "right" price is genuinely hard to pin down and the market is better placed to find it than a fixed asking price. The method of sale is agreed with you in writing in the agency agreement before anything goes live, so this is the first honest conversation we have, not an afterthought.
Before the campaign begins: getting the foundations right
Everything that makes an auction work happens before the public ever sees the listing. In this setup phase we:
- Agree the method of sale and sign the agency agreement. Before you sign, I'm required to give you the Real Estate Authority's New Zealand Residential Property Agency Agreement Guide — read it, it's genuinely useful.
- Set the auction date. Most residential campaigns run for around three to four weeks of marketing. That's an industry norm rather than a legal rule, and we'll settle on timing that suits your property and the season.
- Prepare the home — presentation, any pre-market tidy-ups, professional photography and the marketing plan.
- Talk honestly about price expectations, grounded in comparable evidence.
One thing we do not do yet: set the reserve. That comes later, deliberately, once the campaign has told us something real about buyer demand.
Week one: launch
This is the loud week. Your property goes live across the portals buyers actually use — Trade Me Property, realestate.co.nz and OneRoof — the signboard goes up, and the first open homes run. The goal is maximum exposure right at the start, while your listing is fresh and every serious buyer in the market is seeing it for the first time.
From my side, week one is when I start counting. How many enquiries. How many groups through the first open home. Where buyers are coming from and what type they are — families, investors, first-home buyers, downsizers. None of this is guesswork; it's the first hard data of your campaign, and I'll share it with you plainly.
Week two: momentum and real feedback
Now the campaign settles into its rhythm. Open homes continue, and interested buyers start doing the serious work that an auction demands of them: ordering builder's reports, requesting the LIM, reading the title and the auction agreement with their lawyer, and talking to their bank about finance. Because an auction sale is unconditional, all of this has to happen before auction day — which is exactly why the buyers who show up ready are the buyers who mean it.
My job in week two is to gather honest feedback and turn it into a clear picture: how many genuinely interested parties we have, what they're saying about price, and where any hesitation is coming from. You'll get a proper weekly update — not a vague "lots of interest," but the actual numbers and what they mean.
Week three: building to the day
As auction day approaches, the pace lifts. Committed buyers finalise their due diligence and their finance, and this is often when a pre-auction offer can appear.
Here's how a pre-auction offer actually works in New Zealand: a buyer makes an offer — usually unconditional, on the auction agreement — before the scheduled date. If you decide it's strong enough to act on, the auction is typically brought forward and that offer becomes the opening bid, with all registered buyers notified so they can compete. Accepting a pre-auction offer doesn't quietly sell the home to one buyer; it triggers an earlier auction where they can still be outbid. The trade-off is real: bringing the date forward shortens your marketing window, so whether to accept one is a decision we weigh up together, on the facts.
Late in week three we also have the reserve conversation. The reserve is the minimum you're prepared to accept, it's confidential to you, me and the auctioneer, and it's set on the evidence your campaign has produced — buyer numbers, feedback and comparable sales — not on a hopeful number picked out of the air.
Auction day: how it actually runs
On the day, the process is precise and it protects you at every step:
- Bidders register. Buyers will usually need to register before they can bid, and anyone bidding by phone or in absence arranges that with the auctioneer in advance.
- The auctioneer runs it impartially. They can place vendor bids on your behalf, but only below the reserve and only when each one is clearly announced as a vendor bid. Undisclosed "dummy" bids are illegal — this is a transparent process, not a stage-managed one.
- The reserve stays confidential. Once bidding reaches your reserve, the auctioneer announces the property is "on the market" — meaning it will now sell to the highest bidder.
- The fall of the hammer. When the hammer falls above the reserve, a binding, unconditional contract is formed on the spot. There are no finance or building conditions and no cooling-off period, which is why all the checking happened beforehand. The buyer signs the agreement — commonly the ADLS/REINZ form — and pays the deposit, usually around 10 percent as specified in the auction terms.
And you stay in control throughout. The reserve is yours; it can only be lowered during the auction if you confirm the new figure in writing first. You can even withdraw the property before the auction starts. The auction format creates urgency and competition for buyers, but it never takes the final decisions out of your hands.
What if it doesn't sell under the hammer?
If bidding doesn't reach your reserve, the property is "passed in." It hasn't sold, and the highest bidder is usually given the first chance to negotiate with you. From there we can often do a deal by negotiation, or keep marketing under another method. Passing in isn't a failure — sometimes it's simply the market telling us the best buyer needs one more conversation. It happens, we plan for it, and we keep moving.
Why the "facts first" approach matters most at auction
An auction concentrates a huge amount of decision-making into a short, high-energy window. That's exactly why it rewards a calm, evidence-based approach. The sellers who do well at auction aren't the ones who got lucky on the day — they're the ones who set a realistic reserve on real campaign data, whose home was genuinely ready, and who understood every step before it arrived.
That's the part I take seriously. My job isn't to sweep you along; it's to make sure that by auction day you know precisely what's happening and why, so the only thing left to feel on the day is the good kind of nervous. We do this together, and we do it on the facts.
Auction questions sellers ask me
How long is a typical auction campaign in New Zealand?
There's no legal minimum, but most residential auction campaigns run around three to four weeks of marketing before auction day. The exact length is something we agree together, based on your property, the time of year and how buyers are responding.
Who sets the reserve price?
You do. The reserve is the minimum price you're willing to accept, and it stays confidential between you, me and the auctioneer. The property is "on the market" and will sell once bidding reaches your reserve. It can only be lowered during the auction if you confirm the new figure in writing first.
What happens when the hammer falls?
When the hammer falls above the reserve, a binding, unconditional contract is formed on the spot. The winning bidder can't add finance, builder's report or LIM conditions, and there's no cooling-off period — which is why serious buyers do their homework beforehand. The buyer signs the agreement and pays the deposit, commonly around 10 percent as set out in the auction terms.
Can a buyer make an offer before auction day?
Yes — a pre-auction offer, usually unconditional. If you decide it's worth acting on, the auction is typically brought forward and the accepted offer becomes the opening bid, with all registered buyers notified so they can compete. The buyer can still be outbid. The trade-off is that it shortens your marketing time, so it's a decision we make together.
What if it doesn't reach the reserve?
The property is "passed in" — it hasn't sold, and the highest bidder is usually given the first chance to negotiate with you. From there you can sell by negotiation or keep marketing another way. Passing in is a normal outcome, not a failure.
