NSW consumers are being warned not to deal with a dodgy tradie who may be "up to his old tricks", says the state's Minister for Better Regulation.

Convicted and unlicensed tradie Peter Hynes, also known as Peter Garay, who often trades under the Captain Trade Group, was in 2015 ordered to pay $20,000 for failing to deliver goods and services.

The 48-year-old, known to abandon work after requesting large sums of cash as a deposit, is out targeting people again, warned the minister Matt Kean on Wednesday.

Previous complaints against Hynes include incomplete or unsatisfactory residential building work contracted for driveways, fencing, retaining walls and landscapes.

Mr Kean issued the warning for people not to engage with Mr Hynes or his company and to report any issues to NSW Fair Trading.

“Hynes has never held a contractor licence,” Mr Kean said in a statement.

“I’m frustrated to hear that he is up to his old tricks again.”

Mr Hynes’ victims are also unable to claim from the Home Building Insurance Fund due to him never being licensed.

Wednesday’s warning follows the jailing of another unlicensed builder, Matthew Geoffrey Rixon, who is serving at least 12 months behind bars after ignoring court orders that banned him from working in the industry.
