In April 2026, a 92-year-old New Zealand woman lost almost everything she had to a scammer impersonating a tradie. The story made national headlines — and it should concern every legitimate tradie in the country. Not just because it's a terrible outcome for a vulnerable person, but because it demonstrates exactly how badly fake operators can damage the reputation of genuine, hardworking tradespeople.
Scams involving fake tradies are on the rise in New Zealand. As winter arrives and homeowners start booking maintenance work — roof checks, insulation upgrades, heat pump servicing, plumbing repairs — the conditions are ripe for opportunistic fraudsters to exploit. This guide covers what's happening, how it affects your business, and practical steps you can take to protect yourself and your customers.
The Fake Tradie Problem in New Zealand
The typical fake tradie scam follows a familiar pattern. Someone doorknocks or phones a homeowner, offers an urgent repair or inspection (often at a suspiciously low price), collects a deposit or full payment upfront, and vanishes. Sometimes they perform low-quality work that causes further damage. Often they do nothing at all.
These operators have no LBP licence, no GST registration, no public liability insurance, and no accountability. When the homeowner lodges a complaint or seeks redress, there is no legal entity to pursue.
For legitimate tradies, the downstream damage is real:
- Trust erosion. After a bad experience, homeowners become suspicious of all trade quotes, especially cold approaches or competitive pricing.
- Reputation contamination. If a scammer is using a similar business name or even your personal name, you may receive complaints you know nothing about.
- Price pressure. Scammers undercut the market with phantom pricing that no legitimate operator can match. This creates customer expectations that erode your margins.
How to Make Your Business Scam-Proof (for Customers)
The best defence is making it unmistakably clear that you are a legitimate, verifiable operator. Here's how:
1. Publicise your LBP or trade licence
If you do restricted building work, your LBP number is publicly searchable on the MBIE building practitioner register. Include it in your quotes, email signature, and website. Scammers cannot fake a real LBP number tied to a name.
Electricians, plumbers, and gasfitters are similarly licensed through the Electrical Workers Registration Board and Plumbers, Gasfitters and Drainlayers Board. Display these credentials prominently.
2. Show your GST number and IRD registration
Any tradie earning over $60,000 per year must be registered for GST. If you're registered, include your GST number on every invoice. Customers can cross-check it at the IRD. A scammer operating cash-in-hand has no GST number to show.
Even if you're under the $60,000 threshold and GST registration is voluntary, being registered and displaying your number adds credibility. Use our GST calculator to understand when registration makes sense for your situation.
3. Use a proper contract — every time
A written contract is the single biggest differentiator between a legitimate tradie and a fraudster. It protects you legally and reassures customers that you stand behind your work.
Your contract should cover scope of work, payment terms, variations process, and dispute resolution. For a practical guide, see our article on writing tradie contracts in New Zealand. And for getting paid on time once the work is done, read our guide on how to get paid faster as an NZ tradie.
4. Limit upfront deposits
Scammers often ask for full payment upfront. Legitimate tradies generally ask for a modest deposit (10–30% for larger jobs) and invoice on completion or at agreed milestones. If a customer seems nervous about a deposit, explain your payment structure clearly. Transparency builds trust.
For large projects, consider progress billing tied to milestones rather than large upfront sums — this protects both you and the customer.
5. Get verified on Builderscrack or a similar platform
Verified profiles on Builderscrack, Trades Hive, or similar NZ platforms include reviews, ID verification, and trade credentials. They give customers an independent way to confirm you're who you say you are. A presence on one of these platforms is increasingly expected by cautious homeowners.
Digital Tools That Help
Fastcrew is a New Zealand-built tradie app that handles job management, invoicing, and customer communication in one place. Using a professional app like Fastcrew means every customer interaction — quote, update, invoice — arrives via a branded, professional interface rather than an informal text or handwritten note. It also creates a digital paper trail that protects you if a dispute arises.
For customers, receiving a quote or invoice through a legitimate business platform is a reassuring signal that distinguishes you from informal cash operators and outright scammers.
What to Do If Someone Is Impersonating You
If you discover a scammer is using your name, phone number, or business details:
- File a complaint with Consumer NZ and notify your local police. Impersonation for financial gain is fraud.
- Alert WorkSafe if the scammer is posing as a licensed tradesperson or performing regulated work without credentials.
- Post a notice on your own website and social profiles clarifying your legitimate contact details.
- Notify your trade association (Master Builders, Masterplumbers, NECA, etc.) as they may be able to issue a wider warning to the industry.
- Contact IRD if the scammer appears to be misusing a GST or IRD number linked to your records.
Protecting Vulnerable Customers
Winter is peak season for cold-call tradie scams targeting elderly homeowners. If you genuinely care about the communities you work in, consider:
- Placing a warning note on your invoices: "A legitimate tradie will always provide written quotes and never demand full payment upfront."
- Sharing Consumer NZ's tradie scam guidance on your social channels.
- Being willing to provide references or direct customers to your online reviews before a job starts.
This isn't just good ethics — it's good marketing. Customers who feel protected by you become loyal, repeat clients.
