Holcim has a five year sponsorship with the West Coast Blue Penguin Trust, helping to provide assistance for tracking and counting colonies of blue penguins, to better understand the nature of their breeding and migrations, as well as carry out habitat enhancement, predator control and planting to help improve the area. Holcim has a particular interest in helping to enhance penguin habitat near its Cape Foulwind quarry.

Construction of Westport's recreation & events complex at McDonald Park was supported by a significant contribution from Holcim New Zealand. The complex includes an aquatic centre, dry court facility, fitness centre, hockey turf, two squash courts and seminar and meeting rooms.

Students at Hukanui Primary School researched eco-friendly building materials and worked with a Hamilton architect to design New Zealand's first eco-classroom, with an ecological footprint half the size of a normal classroom. Holcim New Zealand sponsored the project by providing concrete for the classroom floor.

The creation of a wetland and bird sanctuary on eight hectares of Holcim land at Cape Foulwind was announced in 2008 as a community project to mark the 50th anniversary of operations commencing at Westport Works. The wetland site, used for quarrying up until the 1960s, is being turned into a unique wetland habitat complementing existing conservation projects at Cape Foulwind. Features will include a series of small lakes, a walkway around the wetland, a bird hide, and interpretative panels explaining the wetland eco-system. Local school children and other community members are being given the opportunity to be involved in planting.

Holcim New Zealand has, since 2003, sponsored a part-time teaching and research position at the University of Canterbury School of Engineering. Professor Des Bull, who holds the position, is working with the building industry on concrete construction technologies.

For more than 25 years Holcim has awarded a tertiary study scholarship at Westport. The scholarship pays $2000 per year for up to four years of study, as well as providing holiday work at Holcim Westport Works. Since 2009, scholarships have also been offered to communities relating to our Hastings Quarry, Bombay Quarry and Kiwi Point Quarry (Wellington)
