About
GR Environmental Lining has been installing geomembrane liner systems across New Zealand since the early 1990s. Over 30 years and five million square metres later, the work still comes down to good people doing it properly.
Thirty Years of Liner
Installation. We're still at it.
Our Story
Graham Rogers founded the company in Whangarei and built a reputation over three decades on the quality of the work – effluent ponds, reservoirs, landfills, containment systems.
In 2026, the business changed hands, but Graham has stayed on as part of the team to ensure his unmatched industry knowledge is passed on.
We’re committed to continuing the exceptional standards GRE Environmental Lining was built on, while continuing to strengthen the business to support the next generation of work.
