About Kate Valley
Every community needs infrastructure it can rely on.
Infrastructure. Renewables. Conservation. Partnerships. Four commitments, one purpose: lasting value for communities, the environment and the generations still to come.
At the centre is Kate Valley Landfill. Alongside it, the Gareth James Energy Park turns landfill gas into renewable energy for up to 4,000 homes. Tiromoana Bush is 20 years into a 300-year regeneration vision. And through the Kate Valley Group Community Trust, that value keeps returning to the communities around it.

Thinking in Generations.
Every decision is measured against the generations that follow, not the next quarter. Infrastructure engineered to last. Renewable energy. Conservation. Partnerships that endure. Value measured long after we’re gone.
