About this programme

The building and construction industry is one of Aotearoa New Zealand’s largest waste producers, contributing up to 50% of
all waste going to landfills. As the country looks to reduce its greenhouse gas emissions, the efforts to minimise construction and demolition waste is becoming increasingly important for industry and government players.

In 2024, Manatū Mō Te Taiao | Ministry for the Environment (MfE) and the Hīkina Whakatutuki | Ministry of Business, Innovation and Employment Building for Climate Change programme are leading significant changes to building regulation in relation to waste minimisation.

To adapt, the industry needs new strategies and resources to tackle construction and demolition waste. In partnership with MfE, this project will bring together government, industry and researchers to support and co-create coordinated action. It seeks to drive waste minimisation behaviour change within the sector by changing agendas, enhancing knowledge, and improving decision making.

Exploring the existing information gaps and barriers to reducing waste, this research project will increase industry awareness by updating resources and guidance. By increasing knowledge and nurturing new approaches to waste minimisation, it aims to enable a smooth and equitable introduction of these regulatory changes to the building system.

As these new changes come into effect, the industry needs to be both inspired to act and equipped with the tools and resources it will need to make a positive change. When it comes to developing industry waste minimisation capacity, there is no time to waste.
