The Real Risks of Cash Jobs in New Zealand

Everyone knows someone who gets their work done "cashie". The mate's-rate deck, the no-GST discount, the tradie who can "do it cheaper for cash". It's so normalised in New Zealand that asking about the risks feels precious.

But the discount has a price, and it shows up at exactly the worst moment: when something goes wrong. Here's the honest accounting, for both sides of the cash job.

What you're actually giving up as the customer

No paper trail means no leverage

With no invoice and no payment record, the job legally may as well not exist. The deck leaks six months later? Your word against theirs about who did it, what was agreed, and what it cost. The Disputes Tribunal and the courts work on evidence, and a handshake plus a withdrawal slip is barely any.

The Building Act warranties still apply, but good luck

In theory, the implied warranties in the Building Act cover residential building work regardless of how you paid. In practice, enforcing them against someone with no paper trail, no fixed address you can prove, and possibly no registered company is an uphill climb. A warranty you can't enforce isn't worth much.

Insurance can get awkward

If unconsented or shoddy cash work contributes to a loss (a fire from non-compliant wiring, a leak from unconsented plumbing), your insurer will look hard at the claim. "I got a mate to do it for cash" is not a sentence you want in a claim conversation.

What the tradie is giving up

Cash jobs cut both ways. The customer who wants no record today is the customer who can simply not pay you tomorrow, and you'll have the same evidence problem they do. You're also carrying the whole tax risk yourself: undeclared income is IRD's problem to punish, not the customer's, and "they offered me the cash price" is no defence. Tradie-side, the smarter play is getting paid properly with the money visible up front.

The tax problem is real

A genuine cash-job discount usually exists because GST and income tax aren't being paid. IRD has been open about the construction sector being a focus, data-matches aggressively, and the penalties fall hardest on the tradie. The "saving" is someone else's tax debt with interest compounding.

The alternative isn't "pay full price and hope"

The thing people actually want from a cash deal isn't tax evasion. It's a fair price and a job that gets finished. You can have both with structure:

1. A written quote so scope and price are fixed.
2. A protected payment so the money only moves when the work is approved. With wlbr task, you post the job, get offers from verified local operators, and fund the accepted offer into an NZD trust account. The operator sees the money is real; you release it when the work's done right.
3. A proper record of every payment, automatically. Every protected payment comes with a receipt and a ledger entry both sides can see.

That combination gets you what the cashie promise was supposed to be: competitive price, real accountability, and someone who shows up to finish, because finishing is when they get paid.

The bottom line

A cash job is a bet that nothing will go wrong, priced at 15% off. When the bet loses, you have no contract, no leverage, no insurance comfort, and a tradie with no reason to answer the phone. Keep the competitive pricing; lose the no-paper-trail part.
