Commercial & Bulk Supply

Supplying Food Grade Diatomaceous Earth to New Zealand’s Commercial Sector

DENZ Ltd supplies high-quality food grade Diatomaceous Earth (DE) to commercial operators, distributors, and industrial users across New Zealand.

We understand that commercial environments require consistency, reliability, and clear supply standards. Our focus is on dependable product quality and practical bulk logistics.

Product Overview

Food grade Diatomaceous Earth is a naturally occurring amorphous silica mineral formed from fossilised diatoms.

It is valued for its:

  • Fine particle profile
  • High natural silica content
  • Large surface area
  • Absorbent mineral structure
  • Stability in dry environments


As a mineral material, Diatomaceous Earth functions through physical characteristics rather than chemical action.

Commercial Environments

In many international markets, food grade Diatomaceous Earth is utilised in a range of dry bulk and storage environments, including:

  • Bulk storage facilities
  • Dry material handling systems
  • Warehousing infrastructure
  • Agricultural and industrial supply chains


Under New Zealand’s Agricultural Compounds and Veterinary Medicines (ACVM) Act, we are limited in the application-specific information we are permitted to publish online.
