Mr. John Wickham:

In relation to the marketing of construction products, legislation exists on construction products regulations. They establish the rules by which we put products on the market. To enforce that system, there is an authority over market surveillance. On a State-wide basis, the National Building Control and Market Surveillance Office leads on that, with support of the individual 31 local authorities. Anyone who is aware of defective material or non-compliant material in the marketplace should engage with those authorities as the first port of call.
