Quick answer: New Zealand construction firms are failing at a rate of roughly 14 a week, but not because the work has dried up. Building activity actually grew for the first time in almost three years in the June 2026 quarter, and consents are at their highest level since 2023. Companies are going under because of margin and cash timing: fixed-price jobs signed on old costs, progress payments arriving later than the bills, unbilled variations, and an IRD that has stopped waiting for its GST and PAYE. Busy and profitable stopped being the same thing.
Here's what the numbers actually say, and what the firms still standing are doing differently.
The numbers, straight up
Credit bureau Centrix counted 755 construction company liquidations over the past year, which is about 0.9% of every registered construction company in the country. Total company liquidations across all sectors hit 3,073, up 15% and the highest in 11 years. Construction was the single biggest chunk of it.
That's roughly 14 building companies a week closing the doors.
Now put that next to the activity data from Stats NZ. The value of building work put in place hit $8.15 billion in the June 2026 quarter, up 5.2% on the same quarter last year. That is the first positive annual reading since the December 2023 quarter, after nine straight quarters of decline. Residential work did most of the lifting at $5.2 billion, up 11%.
Consents back it up: 40,580 new dwellings consented in the year to June 2026, up 19.4%, and above 40,000 for the first time since 2023.
So the sector is growing and failing at the same time. That combination is the whole story.
It's not a work shortage
Master Builders released its 2026 State of the Sector survey in September, and it lands on exactly this point. Some 68% of builders reported strong or steady pipelines, up from 64% the year before. Only 6% described their pipeline as critically diminished, down from 11%.
Chief executive Ankit Sharma put it plainly: "The work has not disappeared."
What has disappeared is the buffer. In the same survey, 93% of builders named rising construction costs as their top pressure and 87% pointed to weaker consumer demand. Pipelines are holding. Margins are not.
That needs a different fix from a downturn. You cannot sell your way out of a margin problem.
Reason one: the IRD stopped being patient
This is the big change most builders have not fully registered.
Inland Revenue was carrying $9.3 billion in unpaid tax and entitlement debt as at 30 June 2025. That includes $3.3 billion in GST and $2.0 billion in PAYE, with PAYE debt up 33% in a year.
The response has been aggressive. IRD made 650 liquidation referrals in 2024-25, up 49%, issued 16,500 bank deduction notices in a matter of months, ran 7,641 audits (up 42%) and made close to 18,000 visits to business premises. The escalation pathway now starts at debts of $1,000.
Insolvency practitioners looking at collapsed building firms keep landing on the same pattern: GST and PAYE treated as a flexible overdraft when a job runs short, with a plan to true it up on the next progress claim. That worked while IRD was in pandemic-support mode. It does not work now.
The money you collect as GST was never yours. If it is funding your payroll, you already have the problem, you just have not been sent the letter yet.
Reason two: fixed-price contracts signed on last year's costs
Sign a fixed-price contract for a 10-month build and you have effectively bet that your material and labour costs will not move for 10 months.
They will. Construction price inflation has slowed but has not stopped, with residential prices up 1.4% in the June 2026 quarter alone. And the Reserve Bank has now started pushing rates the other way, lifting the OCR 25 points to 2.75% on 2 September 2026 after inflation hit 4.1% in the June quarter. Nobody had that in the plan at the start of the year.
If your quote is built from a spreadsheet you last updated in autumn, the difference comes out of your pocket. Every time.
The fix is not complicated, it just has to be systematic: price off current supplier rates, quote from real takeoffs rather than gut feel, and make sure your charge-out rates actually cover your overhead. A lot of NZ builders are still charging out labour at a rate they set when their wage bill was smaller.
Reason three: the cash arrives after the bills
Long residential jobs are a timing trap. You pay the crew weekly and suppliers on the 20th, then get paid at deposit, frame, lock-up and completion. Stretch terms to 60 days and the gap gets ugly.
Then there's retentions. Money withheld under the Construction Contracts Act has to be held on trust and reported on, but the temptation for a firm under pressure is to treat it as working capital and square it up later. When a firm collapses holding other people's retentions, it takes subbies down with it. That's a big part of how one failure becomes three.
The practical protection is boring and it works: invoice the moment a stage is complete rather than the end of the month, get staged progress claims out automatically, and know your cash position three months ahead rather than three weeks.
Reason four: variations that never got billed
Ask any liquidator and this one comes up constantly. The client moves the laundry, the demo uncovers rot, the engineer changes the beam spec. The crew does the work because that's what good builders do. Then it never gets quoted, approved or invoiced.
On one job that's a bad week. Across a year of long jobs it's your entire margin, and you never see it go because it never appears on an invoice.
Every variation needs to be captured on site, priced, approved in writing and pushed into the claim. If that process lives in someone's head or in a text message thread, it is not a process.
Reason five: you don't know which jobs are losing money
This is the one that turns a bad year into a liquidation.
If your job costs are reconciled at the end of the build, or worse at the end of the financial year, you find out you worked March for free in about September. By then you have quoted four more jobs the same way.
Back-costing while the job is running is the difference between a bad job and a bad business. Quoted versus actual on labour and materials, checked weekly, so you can do something while there is still job left to fix. That means crew time going onto the job from site via a phone in a pocket, not a pile of paper dockets landing in the office on Friday.
Reason six: consenting delays and where you're building
Two things outside your control that still hit your P&L.
Consenting delays affected 68% of projects in the Master Builders survey and were the biggest single cause of significant delays. Every week a job sits waiting is a week of overhead with no revenue against it. The consent system reform and the granny flat exemption should help, but not fast enough to save anyone this year.
Location matters more than usual too. Canterbury just posted its best quarter on record at $1.44 billion, up 13.9%, and Waikato is up 11.6%. Wellington went the other way, down 8.9% to $591 million, its weakest June quarter since 2020. Same country, completely different market.
What the survivors are doing differently
The building companies coming through this are not the ones with the fanciest jobs. They are the ones who:
- Know their true cost per hour and charge it, rather than matching the bloke down the road.
- Reprice quotes against current supplier rates instead of last year's spreadsheet.
- Bill variations as they happen, without exception.
- Get progress claims out the day the stage is done.
- Keep GST and PAYE in a separate account and treat it as untouchable.
- Look at quoted versus actual weekly, per job, not per year.
- Plan the crew across several jobs at once so nobody is standing around waiting on a consent.
None of that is glamorous. All of it is the difference between a busy year and a profitable one.
FAQs
How many construction companies are failing in New Zealand?
Around 755 construction companies went into liquidation over the past year, which is roughly 0.9% of all registered construction companies and about 14 a week. Construction is the largest single contributor to a total of 3,073 company liquidations across all sectors, an 11-year high.
Is the New Zealand construction industry actually in decline?
Not any more, on the activity numbers. Building work put in place grew 5.2% in the June 2026 quarter, the first annual increase since late 2023, and consents are at their highest since 2023. The failures are being driven by margin and cash flow rather than a lack of work.
Why is IRD liquidating so many building companies?
Inland Revenue is carrying $9.3 billion in unpaid tax and has shifted from pandemic-era leniency to active enforcement, including a 49% increase in liquidation referrals and thousands of bank deduction notices. GST and PAYE arrears that would have been tolerated a few years ago now trigger action, starting from $1,000.
What is the most common reason a NZ building company goes broke?
Running out of cash while holding a full order book. The usual chain is a fixed-price job priced on old costs, variations that never got billed, progress claims sent late, and tax money spent on payroll to cover the gap.
How do I know if my jobs are actually profitable?
You need quoted versus actual costs per job while the job is still running, not after handover. That means labour hours recorded against the job from site, materials coded to the job as they land, and a weekly look at the variance. If you can only answer the question at year end, you are finding out too late to change anything.
The bottom line
New Zealand construction is not short of work. It's short of margin, and short of the systems that protect margin on long, staged jobs with variations, subbies and progress claims. That's why firms with full pipelines are still going under, and it's also why the fix is within reach for most of them.
If you're a builder, carpenter or renovation crew running a few long jobs at a time, getting quoting, timesheets, variations and job costing into one place is the single highest-leverage thing you can do this year. NextMinute was built for exactly that shape of business, it syncs with Xero, and there's a free trial if you want to see your own numbers in it.
There's also a guide to surviving tough times in construction if you'd rather start there, and if you're wondering where your good people went, that's a related story.
