NZ Housing Market in August 2026: Value-Add Renovation Play

Cotality’s Monthly NZ Housing Chart Pack for August 2026 (July data) is the national bellwether report. FindMyProperty’s focus is not the global set of NZ residential property sales. Instead, our clear focus remains on value-add renovation, forcing the capital appreciation, changing the narrative from following the market to being your own destiny.

How to read this report

Cotality counts agent and private sales across the country. We count listings that passed our filters and, for the scored tables below, have a composite score. Asking price is either on the listing already or determined by our in-built smarts. Sold price is what we captured when the listing was sold.

• Overall report: Cotality chart pack, August 2026 (July edition).
• Our baseline: listings sold up until this report was published, 28 August 2026.
• Sub-$750k: as usual our listings are filtered for the national median price where value appreciation has headroom.
• 15% flip ROI and 9% yield are the same gates as how we score listings.

National print: July 2026

There were 6,935 property deals in July — estate-agent and private — down 6.4% on July 2025, the seventh drop in a row. The 12-month running total eased to 89,385 from December’s mini-peak of 91,411. Cotality’s line is that buyers are in no rush because listings are plentiful, and vendors in work are not capitulating either. Values followed: the Home Value Index fell 0.3% in July, 1.0% over three months, and 0.7% over 12 months. The national median still sits 17.7% below peak.

Wellington remains the weak main-centre from peak (−26.5% on Cotality’s median-value series). Christchurch is the least damaged (−1.2% from peak) and was the only main centre in that three-month window with a positive print (+0.2%). First-home buyers are still the force: 29.0% of July purchases, a new monthly record, with their deal count still rising while overall activity falls. Mortgaged investors (multiple property owners) ticked up to 24.1% after a soft first half; Cotality’s own caveat is cashflow squeeze, election risk, and possible tax change. Movers stay under 25%. That mix is why a cosmetic do-up below the national median still has someone to sell to — and why a thin-yield hold is harder to refinance.

The FindMyProperty book: sub-$750k, scored, active

On 28 August 2026 the live scored book with an asking price at or under $750,000 was 1,001 listings. Median ask $479,000. Median modelled after-repair value $575,125. Median renovation estimate $63,250. Median composite score 50.6 — indicating the challenges faced when trying to unlock value, whether to onsell or refinance. Seventy-six listings still cleared 15% flip ROI. That is the whole point of a screen in a buyer’s market: most stock is not a deal.

The >$750k scored slice is small because the engine is built for the sub-$750k value-add thesis. The comparison still matters: almost all of the 15% hits sit in the cheaper band (76 versus 4), and modelled yield is higher there (4.6% versus 3.3%) — still nowhere near the 9% rental gate. Verdict mix on the 1,001: 4 Strong Buy, 369 Buy, 565 Maybe, 63 Pass. Strategy labels on the same slice included 150 FLIP / FLIP_WITH_SUBDIVISION rows. Treat the 76 as the hard 15% count; older runs can stamp FLIP at a slightly different threshold.

Reno level: cosmetic still prints the 15% hits

Of the 1,001 active scored sub-$750k listings, 470 were classed cosmetic (median reno $40,000) and 434 moderate (median $95,000). Major and full-gut were 77 and 10. The 15% flip-ROI hits were 49 cosmetic, 22 moderate, 4 major, 1 full gut. That matches the bang-for-buck renovation rule: consent-light work in a deep buyer band, not a vacant gut into a 50-day market. Cotality’s 27,336 listings and 50-day-class tape (see flip or hold, August 2026) punish timeline.

Sold outcomes in the same band

Between 4 April and 27 August 2026 we recorded 3,515 passed listings that sold with both a sold price and asking at or under $750k. Median ask $500,000. Median sold $510,000. Median result versus ask: −0.7%. 1,843 sold below ask; 1,672 at or above. Marketing method on that priced sold set was almost all negotiation (1,816) or asking-price (1,686) — not auction.

Median sold sat 16.5% below modelled after-repair value. Read that as ARV doing its job, not as a miss: ARV is the renovated comparable, and these sales are the as-listed exit. If your flip only works because the next buyer pays the ARV without the works, it is not a flip. 651 of those sold rows had modelled 15%+ flip ROI while they were still live — a reminder that a passing score is an entry screen, not a guaranteed clearing price.

Where the 15% hits sit

Among active scored sub-$750k listings with at least 15 rows in a region, the 15% flip-ROI counts on 28 August 2026 were: Auckland 12 (median ask $650,000), Otago 11 ($439,500), Waikato 10 ($505,000), Taranaki 10 ($464,000), Wellington 8 ($520,000), Canterbury 7 ($459,000), Northland 5 ($499,000), Manawatū / Whanganui 4 ($419,500), Hawke’s Bay 4 ($495,000), Bay of Plenty 3 ($517,000). Southland had 49 scored listings in the band and zero at 15% flip ROI (median modelled ROI −12.1%). Cheap is not the same as a deal.

What this means if you flip or hold

Cotality’s FHB record (29.0%) is the resale-depth argument for staying under $750k: you are selling into the buyer class that is still transacting. Their mortgaged-investor share at 24.1% is not a signal to pay up; the same pack notes flat rents, rising costs, and another OCR step. Stats NZ new rents were only +0.8% in the year to July. Our book’s 4.6% median modelled yield is better than the national high-3%s because the asks are lower — it still does not print 9%. Hold only if the cashflow works at today’s rent and a higher servicing rate than the July 2.50% OCR.

Flip only if the margin is in the buy: 76 listings modelled 15%+ on a −3.5% median book, and solds in this band cleared a median 0.7% below ask, not above ARV. Pair that with the flip-or-hold Cotality Pain and Gain print (13.1% of Q2 resales at a gross loss; 4.3-year holds on losses versus 10.4 years on gains). Short hope is the loss cohort. Cosmetic scope in this band is the slice that still models.
