New Zealand's native species are under pressure in some areas and as a business with large land holdings we're in a position to make a net positive contribution to the environment.

Our Biodiversity Action Plan is a strategy for reducing the environmental impacts of our quarrying activities, while still providing society with the aggregates it needs for roads, buildings and industry. Our view is long term - it's not just a matter of finishing an operation then packing our bags. Each site has its own rehabilitation strategy which includes replanting native bush, reshaping the land or backfilling it to create ponds and pasture.

"We cannot continue to think of protected and productive places separately... we have to manage this biodiversity as best we can in farming and forestry environments and alongside marine industries, while ensuring a sustainable return from these activities."
