About Us


Our History

Comprehensive Engineering Solutions in Christchurch, Timaru, Hamilton, Nelson and Dunedin
In 1991 Design Engineering was established to provide: structural steel detailing, mechanical engineering design, welding inspection and welder qualification testing. Over the next few years the business expanded to include structural engineering design, non destructive testing as well as equipment inspections including cranes, PEI, High Voltage Testing, Calibration and elevating work platform inspections.

In early 2021 a major restructure was implemented and the DE Group was formed. This includes three separate limited liability companies trading as the Survey NZ, DE Consulting Engineers & Inspection and DE Calibration & Compliance.

As part of DE Group, DE Calibration and Compliance  or DE Calcom for short focuses on providing calibration and verification testing, high and low voltage equipment testing as well as elevating work platform inspections.
