World-class environmental management since 2005
Welcome to Kate Valley, the home of Tiromoana Bush, Canterbury’s 407-hectare regenerating lowland native forest, the Gareth James Energy Park that produces renewable electricity from methane gas and the Canterbury Regional Landfill.
Located in the Hurunui District, one hour’s drive north of Christchurch City, Kate Valley is owned by Transwaste Canterbury, an innovative public-private partnership, bringing together the Christchurch City Council and District Councils of Ashburton, Hurunui, Selwyn and Waimakariri, and WM New Zealand Ltd, the largest private waste company in New Zealand. Since 2005 we’ve been trusted managing our community’s waste to the highest environmental standards at our Kate Valley Landfill and Gareth James Energy Park.

Conserving New Zealand’s native bush
We’re environmental managers committed to create a better environment for future generations to enjoy. That’s why we’re funding an ambitious conservation project in Kate Valley to regenerate a 407-hectare lowland native forest at Tiromoana Bush, on land adjacent to the regional landfill. We’ve built a series of walkways, lookouts and picnic spots through Tiromoana Bush because we want people to experience being in a regenerating native forest, complete with wetlands and birdlife.
A world-class, modern engineered landfill
The Kate Valley Landfill and Gareth James Energy Park is an outstanding example of a world-class, modern engineered landfill, designed to the highest international standards and operated to ensure the environmental impacts are managed and mitigated. Gas from the landfill is used to generate electricity, enough to power more than 2,000 homes in 2023, and up to potentially 8,000 households in the future.
Educating future generations about waste
Transwaste has been welcoming students to learn how the region’s waste is managed since the Kate Valley Landfill and Gareth James Energy Park opened. In addition to arranging on-site tours, Transwaste has online resources, including videos, about the management of waste and operation of the Kate Valley Landfill and Gareth James Energy Park free and available to students and their teachers on this website.
