What is Diatomaceous Earth? (New Zealand Guide)
Diatomaceous earth is a naturally occurring soft sedimentary rock formed from fossilised microscopic algae known as diatoms. In New Zealand, high-quality diatomite deposits provide a reliable and natural source of diatomaceous earth suitable for a range of applications.
What is Diatomaceous Earth?
Diatomaceous earth (often referred to as DE or diatomite) is composed primarily of silica and is formed from the fossilised remains of ancient diatoms. These microscopic organisms accumulated over millions of years, creating a porous, lightweight material with a wide range of industrial and agricultural uses.
Common Uses of Diatomaceous Earth
Filtration media (water and industrial systems)
Absorbent material for spills
Agricultural and horticultural use
Soil conditioning and moisture control
Industrial applications
Why New Zealand-Sourced Diatomaceous Earth Matters
New Zealand-sourced diatomaceous earth is valued for its natural purity and consistency. Locally mined diatomite reduces the risk of contamination from transport and long storage times. Our material is excavated fresh from the quarry, ensuring a clean and reliable product. Sourcing locally also supports New Zealand industry and reduces supply chain delays.
Freshly Mined Diatomite from Rotorua
Our diatomaceous earth is sourced directly from our quarry near Rotorua. The material is excavated fresh to maintain its natural properties and minimise contamination. We supply bulk quantities and can arrange delivery across New Zealand.
