Is Autumn a Bad Time to sell homes in Mairangi Bay and surrounds? The Data Says Otherwise.

Every April, the same conversation starts. Vendors begin to wonder whether they've missed the window. Their neighbours sold in September. Their friends listed in October. The market "slows down" in autumn, everyone says, and winter is worse. You should have listed six weeks ago. Wait until next spring.

It is one of the most repeated pieces of advice in New Zealand real estate. It is also one of the least examined.

I pulled 430 residential sales across Campbells Bay, Mairangi Bay, Murrays Bay, Rothesay Bay, and Windsor Park — the full stretch I call Mairangi Bay & Surrounds — covering every recorded transaction from April 2025 through April 2026. The data does not support the myth in the way most people assume.

What the Numbers Actually Show

Yes, spring produces the highest median sale prices. That part is accurate. But the gap between seasons is considerably smaller than vendors believe, and the picture changes entirely once you account for the number of competing listings on the market at the same time.

Spring's median: $1,691,500. Autumn's median: $1,565,000. A difference of $126,000 — or 7.5%.

That is real. But in spring, there are approximately 43 competing sales per month in this area. In autumn, that falls to around 33. You are entering a market where buyer demand has not disappeared — but vendor supply has thinned considerably.

Fewer Listings, Different Buyers

The standard argument for spring is that buyer activity peaks. More people are looking. That is true. But more people looking also means more people browsing — families who are casually curious, buyers who are "just starting to think about it," people who will attend six open homes before making an offer on none of them.

In autumn and winter, that group largely disappears. The buyers who are out in the cold, attending open homes in the rain, rearranging their Saturdays in June — they are not browsing. They have a reason to move. A job change. A settlement date. A growing family that cannot wait until September.

"In winter, you get to see a home at its worst. Truly motivated buyers know this — and a well-presented property that performs in winter has already cleared the highest bar a buyer can set."

This is a meaningful advantage for vendors who present well. A home that is warm, well-lit, and thoughtfully staged in July stands out dramatically when most other listings are sparse. The buyer who walks through in winter and loves it has no lingering doubt — they have seen it in its hardest conditions.

Season-by-Season Breakdown homes selling in Mairangi Bay & surrounds

The full picture across all four seasons, based on 430 transactions:

Season	Months	Sales	Median Price	Median Days to Sell	Sold Above CV	Sale/CV Ratio
Spring	Sep–Nov	130	$1,691,500	33.5 days	65%	1.07x CV
Summer	Dec–Feb	90	$1,500,000	51.0 days	59%	1.02x CV
Autumn	Mar–May	111	$1,565,000	44.0 days	50%	0.996x CV
Winter	Jun–Aug	99	$1,480,000	48.0 days	43%	0.98x CV

A few things worth noting here. Autumn's median days to sell — 44 — is actually lower than summer's 51. That is counterintuitive to most vendors. Summer, the supposed "active" season, produces longer sales campaigns on average. The January and February slowdown has a real effect on that number.

The sale-to-CV ratio in autumn sits at 0.996 — essentially at CV. In winter, 0.98x. Neither figure is alarming. Properties in this area are broadly achieving what they are worth year-round; spring simply adds a premium on top of that baseline.

Who Should Consider an Autumn or Winter Campaign?

The data does not suggest every vendor should rush to market in June. Spring works well for a reason — broad buyer pools, emotional energy in the market, and competitive auction dynamics that can push prices. If your property has exceptional street appeal, a large garden that photographs beautifully in bloom, or mass appeal that benefits from maximum exposure, spring remains compelling.

But autumn and winter offer a genuine opportunity for specific vendors:

Properties with excellent presentation and interior quality. 

When competing listings are scarce, a home that is warm, well-maintained, and thoughtfully staged stands out. Buyers have fewer options to compare and less reason to hesitate.

Vendors who cannot wait until September. 

Life does not run on real estate seasons. Settlement deadlines, family changes, and financial decisions do not align conveniently with the spring market. Waiting six months has real costs — carrying costs, opportunity costs, and the uncertainty of what the market will look like when you do eventually list.

Properties where buyer motivation matters more than buyer volume. 

Larger, higher-value homes in Campbells Bay or Murrays Bay often benefit from fewer, more targeted buyer groups — purchasers who have already sold, who know what they want, and who are ready to commit. These buyers do not disappear in winter.

The Right Preparation Changes Everything

The qualifier in all of this is presentation. A property that is cold, dark, and poorly maintained in winter will underperform in any season. The advantage of listing in autumn is available to vendors who are prepared to take it — who have invested in staging, who have addressed deferred maintenance, and who price realistically for current conditions rather than the peak of last spring.

The data across Mairangi Bay & Surrounds is clear: the penalty for selling outside spring is far smaller than the conventional wisdom suggests, and for the right property with the right preparation, it may not be a penalty at all.

"430 transactions. One year. The gap between spring and autumn median prices is 7.5%. The gap in competing listings is closer to 25%. Serious vendors should weigh both sides of that equation."

If you are sitting on a decision about whether to list now or wait until September, I would suggest having that conversation before making assumptions about which season is right for your property. The answer depends on the home, the preparation, and your timeline — not on a general rule that may not apply to your situation.
