We are delighted to announce that Zentera Wool Company has been approved as an ISEAL Community Member. Zentera’s experience in advancing wool certification systems and its commitment to continuous improvement will bring valuable perspectives to our growing membership community. We look forward to working with Zentera to strengthen sustainability systems across natural fibre supply chains.

Zentera Wool Company, formerly The New Zealand Merino Company, is the organisation behind the ZQ certification and ZQ+. Zentera works with over 800 growers across New Zealand, Australia and South Africa.

Following approval by the ISEAL Board on 20 May 2026, ISEAL’s Executive Director, Karin Kreider, said: “I am pleased to welcome Zentera Wool Company as an ISEAL Community Member. Zentera has demonstrated a strong commitment to aligning its ZQ and ZQ+ programmes with internationally recognised good practice for sustainability systems. We look forward to working with Zentera to continue improving their system and supporting credible, transparent and impactful sustainability practices across the wool sector.”

Angus Street, Chief Executive at Zentera Wool Company said: “Our company and our ZQ certification have always been at the forefront of change, and we’re continuously looking for ways to build on best practice and be a step ahead.

“This is an important step in the ongoing work to strengthen the integrity, transparency and impact of our products ZQ and ZQ+. There is a real opportunity for natural fibre supply chains to lead, but only if we can back our stories and product with strong systems and credible evidence.”
