The NSW Minister for Innovation and Better Regulation, Matthew Kean, is warning consumers not to deal with an unlicensed building contractor who's been permanently banned from working in the home building industry.

NSW Fair Trading has brought multiple court proceedings against Matthew Rixon, and issued numerous public warnings since 2012.

"I'm urging consumers to heed this warning and not engage Rixon or any entities associated with him, in any sort of building work," Mr Kean will say today.

Rixon, who has gone by multiple aliases and under various business names, was banned from conducting or being engaged in any residential building work or specialist work by the NSW Supreme Court in April 2013.
