ABOUT
OUR HISTORY
FROMA TIMARU STEEL INSPECTION BUISNESS TO A NATIONAL ENGINEERING GROUP.

THE STORY
THIRTY YEARS,
ONE STANDARD.
Design Engineering was founded by Dean van Buuren, in 1991 in Timaru, initially offering steel detailing, mechanical design, welding inspection and qualification testing. Over time, services expanded to include structural engineering, non-destructive testing and equipment inspections across cranes, pressure systems, electrical gear and elevating work platforms. Branches were added in Christchurch, Dunedin and Hamilton between 2007 and 2014.
In 2018, the company acquired Survey NZ, strengthening its capabilities in ship surveys and land-based inspections. A restructure in 2021 formed the DE Group, comprising DE Consulting Engineers & Inspection, DE Calibration & Compliance, and Survey NZ.
In 2025, the group rebranded as DEG, now operating through DEG Consulting Engineering, DEG Calibration & Compliance, and DEG Survey & Inspection. With a 5-star Impac Prequal rating and deep expertise in NZ compliance frameworks, DEG delivers audit-ready, technically robust solutions nationwide.
