REBRI stands for Resource Efficiency in the Building and Related Industries. Its purpose is to promote, advocate, and assist resource efficiency measures in the building and related industries.

REBRI grew from a collaborative effort (called Project Construction + Demolition) between The Auckland Regional Council, BRANZ, the Auckland City Council (with some funding by the Ministry for the Environment), beginning in 1995. As part of this partnership, research, demonstration projects, sorting trials, an industry advocacy group and a variety of other initiatives were carried out. All of these initiatives showed the value of resource efficiency when applied to the building industry.

More recently, in 2003, the National Construction and Demolition Waste Reduction Project was set up to extend this initiative even further, with the aim of developing tools and helping industry, councils and the community to reduce C&D waste at landfills and clean fills. The resources resulting from this project were developed through close consultation with industry representatives and are freely available on this website. This National Project is sponsored by the Ministry for the Environment, the city Councils of North Shore, Hamilton, Christchurch, Auckland, Manukau, and Waitakere, as well as Rodney District Council, Environment Waikato, BRANZ, RONZ and Winstone Wallboards Limited.
