I, Hon Dr David Clark, Minister of Commerce and Consumer Affairs, pursuant to section 51(1) in Part 3A of the Commerce Act 1986, require the Commerce Commission to carry out a competition study into any factors that may affect competition for the supply or acquisition of key building supplies used to build the major components of residential buildings.

Matters to be considered in the study may include, but are not restricted to:

• The industry structure for key building supplies covered by this study.
• The nature of competition for these key building supplies, including any industry pricing practices or acquisition requirements that impact on competition.
• Impediments to the entry or expansion of new or innovative building supplies, such as “green” building supplies or novel prefabricated products.

For the purposes of this study, major components of residential buildings are the foundation, flooring, roof, walls (structural and non-structural interior and exterior) and insulation.

The Commerce Commission should make its final report for this study publicly available by 6 December 2022.

Dated this 18th day of November 2021.

Hon Dr DAVID CLARK, Minister of Commerce and Consumer Affairs.
