About Us

At SUMNER®, we are passionate about creating feature walling. We source the best masonry finishes and cut them thinly to remove weight and reduce delivery costs. Then we use our specialised adhesive system for long term performance. Our clients get the best look and one that we know will last.

Our History

SUMNER® opened 40 years ago as The Slate and Stone Center Limited. A family business that initially operated in New Zealand's natural stone industry.

For years we imported stone flooring and then later supplied local schist (150mm thick) until supply difficulties made it unfeasible. A new business possibility emerged as the world discovered stone veneer. Stone veneer was a paradigm shift for stone masonry and we introduced it to New Zealand as it was easy to import, much like stone floor tiles. We readily obtained supply from international channels, then rebranded our company as Original Stone Co Ltd, and for the next 20 years, we dedicated ourselves to pioneering the industry in New Zealand.


A New System

Initially, we glued thin stone using the same products and techniques as ceramic wall tiles. However, the stone weighed more which required the development of a new system. Over ten years, we refined our SUMNER® Adhered Masonry Veneer System (SAMV). SAMV is a stand-alone proprietary system using cavity, backing board, adhesive and stone. In 2014 we attained a high-level CODEMARK certification, making us the only stone system in New Zealand to achieve this.


Universal Addoption

Today SUMNER® is a market leader in adhered masonry veneers.

We supply our SAMV components to projects needing adhesion or building compliance. Local brick companies specify and use SAMV for their brick slips.

We still offer an inspiring range of stone veneers and are currently working on multiple projects throughout the country. We'd love to hear from you if you are using adhered masonry veneer.
