I’ve sat with a lot of directors of construction companies over the years.
Not one of them started the conversation thinking their business would end in liquidation. Most of them were good at building. Some were excellent. What caught them out almost never had anything to do with their ability to do the work.
It was the money around the work — the timing of it, the safety of it, the assumptions everyone in the chain was quietly making about it.
If you’re in construction, or you lend to or advise people who are, this pattern is worth understanding properly.
A Sector That Keeps Losing Companies
Construction has been one of the more consistently difficult sectors in New Zealand for several years running. Cost escalation, financing pressure, and softer demand for new builds have combined to push a steady stream of companies — mostly small and mid-sized — into liquidation or voluntary administration.
It’s not one bad year causing this. It’s a structural squeeze that’s been building since the post-pandemic cost spike, and it hasn’t fully unwound. Margins in construction were thin before that squeeze started. They’re thinner now.
What makes this sector different from, say, retail or hospitality, is how the failure spreads. A construction company going under rarely stays contained. It takes subcontractors, suppliers, and sometimes homeowners with it.
Why Construction Fails Differently
Most businesses fail because revenue falls and costs don’t. Construction often fails for a more specific reason: the money that should be there simply isn’t, even when the work is going fine.
A head contractor can have a full order book, happy clients, and a genuine skills base — and still run out of cash, because payment is staged, retentions are held, variations are disputed, and costs are incurred well before the matching payment arrives. Add in one client who pays late, or one subcontractor dispute that drags on, and the gap widens fast.
I’ve seen profitable-looking businesses go under for exactly this reason. On paper, the job made money. In the bank account, the timing never lined up.
Retentions: Money That’s Supposed to Be Safe
Retentions are meant to protect the person paying for the work — a percentage of each payment held back until the job (or a defects period) is complete, as security if something goes wrong.
They’re also one of the most common points of failure I see. Retention money is supposed to be held on trust, separately from a company’s operating funds, under the Construction Contracts Act regime introduced to protect subcontractors specifically because retentions were being absorbed into general cash flow and disappearing when the company holding them collapsed.
In practice, I still see retentions treated as available cash by businesses under pressure. It’s an easy trap: the money is sitting there, the bank account is tight, and using it “just this once” feels manageable. It rarely stays a one-off. And if the company holding those retentions goes into liquidation, the subcontractors who were promised that money are often left as unsecured creditors, chasing funds that were supposed to have been ring-fenced for exactly this situation.
The Squeeze Between Fixed-Price Contracts and Rising Costs
Many construction businesses are still working through contracts priced before costs moved. A fixed-price contract signed when materials, labour, and finance costs were lower doesn’t get more generous when those costs rise. The contractor absorbs the difference.
Layer on payment terms that stretch 60, 90, or more days out, and a business can be doing everything right operationally while its cash position quietly deteriorates. By the time the numbers make that obvious, the gap is often too wide to close through better project management alone.
Warning Signs I See Before a Construction Company Goes Under
A handful of patterns show up again and again, well before the company actually fails:
- Retentions or subcontractor payments being used to cover this month’s costs, with a plan to “true it up” once the next big payment lands.
- GST or PAYE being treated as flexible, because the project cash isn’t where it should be and something has to give.
- The same subcontractors being paid late, cycle after cycle, with each one told it’s a one-off.
- A director who can describe every job in detail but can’t tell you, with any confidence, what the actual cash position looks like three months out.
None of these signs mean liquidation is inevitable. They mean the business has moved from managing a tight sector to running on borrowed time, and it’s worth getting an honest, outside view before that borrowed time runs out.
What Directors and Subcontractors Can Do Now
If you’re a director: get a proper cash flow forecast that separates job-by-job margin from actual cash timing. A job can be profitable and still be the thing that sinks you if the cash doesn’t arrive when the bills do. If retention money or tax money has already been used to bridge a gap, that’s the conversation to have with an adviser now, not after the next payment run fails.
If you’re a subcontractor: know your rights under the retentions regime, ask questions if you’re not confident retention money is being held separately, and don’t let unpaid invoices stack up quietly out of loyalty to a long-standing client. Chase early.
If you’re an accountant or lender working with construction clients: the warning signs above are often visible in the numbers well before a director raises them. A tight but “normal for the sector” cash position this quarter can be next quarter’s liquidation notice.
Construction doesn’t have to be this fragile. But the businesses that come through this stretch of the cycle intact are, almost without exception, the ones who treated cash timing as seriously as they treated the build itself.
Frequently Asked Questions
Q: Why do NZ construction companies keep failing even when they have plenty of work?
Because having work and having cash are different things in construction. Staged payments, retentions, and payment terms mean costs are often incurred well ahead of matching income. A business can have a full order book and still run out of cash if the timing gap isn’t actively managed.
Q: What are retentions and why do they matter?
Retentions are a percentage of payment held back by a client as security until a job, or its defects period, is complete. Under the Construction Contracts Act, retention money is meant to be held on trust, separate from a company’s general funds. When it isn’t, and the company holding it fails, subcontractors can be left chasing money that was supposed to have been protected.
Q: Can subcontractors get their retentions back if a head contractor goes into liquidation?
It depends on whether the retentions were correctly held on trust and can be identified separately from the company’s other funds. If they were properly ring-fenced, subcontractors have a stronger claim to that specific money. If retentions were absorbed into general operating cash, subcontractors are typically left as unsecured creditors, which significantly reduces what they’re likely to recover.
Q: What should a construction company director do if they’re worried about cash flow?
Get a clear, honest forecast of cash in and cash out over the next three months, separate from the profitability of individual jobs. If that forecast shows a gap you can’t close, or if you’ve already used retention or tax money to bridge previous gaps, get independent advice early. The options available before a payment is missed are far broader than the options available after.
