Leighs Achieves ISO Certification – A Milestone in Quality, Safety, & Sustainability

Leighs is proud to announce that we have achieved ISO 9001 certification against our Quality Management System, completing the trifecta and building on our ISO 45001 Occupational Health & Safety and ISO 14001 Environmental system certifications.

✅ ISO 9001 – Quality Management (new!)

✅ ISO 45001 – Occupational Health & Safety ✅ ISO 14001 – Environmental Management

Together, they endorse the effectiveness of our Integrated Management System approach as a robust and auditable framework for the construction industry. This significant achievement underscores our commitment to excellence in project delivery across all areas of the business.

This achievement reflects our commitment to excellence in project delivery and continuous improvement across all areas of our business. Our teams in Auckland, New Plymouth, and Christchurch worked closely to tune and align system elements. The value of this approach led the auditor to acknowledge the maturity and effectiveness of our systems.

The success of the ISO 9001 certification is a collaborative effort from the executive level to the project teams.

I would like to especially thank the project teams, and everyone involved in the audit process. You have demonstrated an outstanding understanding of the requirements and a willingness to work with our systems. — Châu Phạm, Systems Manager

Leighs have always measured and managed quality, and the journey to ISO 9001 certification has been years in the making. This certification strengthens our ability to deliver high-quality projects and reinforces our reputation as a trusted construction partner.

Achieving ISO 9001 certification—alongside our existing ISO 45001 and 14001 certifications—is a fantastic achievement for Leighs, demonstrating our strong focus on quality. It reflects the hard work and collaboration of our team and strengthens our position in the industry.

This certification puts us in a stronger position for future success. — David Jarman, Interim CEO
