Eco Stock Supplies

What Eco Stock Supplies does

Eco Stock Supplies Ltd is a New Zealand-based circular economy operator founded in 2007 by Andrew Fisher that diverts commercial and industrial food waste from landfills and transforms it into high-energy stock feed supplements for ruminant animals and renewable energy via anaerobic digestion. Headquartered at the Wiri facility in South Auckland, the company processes surplus and pre-consumer food from major food manufacturers, importers, and supermarkets using mechanical depackaging, pasteurisation, and a proprietary blending process developed with animal nutritionists; an electronic auditing tool called EcoTrack provides sustainability compliance and traceability reporting to 140+ clients. Through the Ecogas Limited Partnership with Pioneer Energy, Eco Stock also operates New Zealand's first commercial-scale anaerobic digestion facility at Reporoa, processing up to 75,000 tonnes of food waste annually into biogas, and the WormsRus division runs the country's largest retail worm farm, recycling approximately 550 tonnes of food waste per year and partnering with 60 schools.

The company's go-to-market is enterprise field sales targeting food manufacturers and producers, with named blue-chip customers including Goodman Fielder, PepsiCo, Nestle, Griffins, Nespresso New Zealand, and Whittaker's. Services are delivered directly in Auckland and Waikato via Eco Stock's own fleet, and nationwide through third-party logistics partnerships. Revenue is generated through a mix of transaction-based stock feed sales, recurring collection and disposal service fees often offset by the value of recycled feed, and professional services for product stewardship and quality assurance. The company reported annual sales of over $8 million NZD in 2022, employs 35 people (up from 2 at founding), and is 100% Kiwi-owned with no disclosed external funding; it has announced plans to scale to 95 employees within two years, signalling an aggressive capacity-led growth phase.
