Unlicensed builders in the Hunter have been prosecuted as part of a crackdown by New South Wales Fair Trading.

In the last month, four people have been prosecuted over unlicensed building works in New South Wales.

They include Karl Michael Roby, 41, who was convicted in Newcastle Local Court for accepting payment but failing to deliver goods and services, along with unlicensed contracting of residential building work.

He was ordered to pay fines and court costs totalling more than $25,000, and compensation to his three victims of almost $7,500.

Peter Haynes, 45, also known as Todd Garay, was convicted and ordered to pay almost $20,000 in fines and costs.

The Hamilton South man accepted pre-payment from his victims totalling $85,000 for services including wall and fence construction, agricultural drainage and landscaping, turf laying and deck projects.
