Certification, Compliance and Consulting Engineers

Our Team

After working on a wide range of projects in New Zealand, Dean Van Buuren formed Design Engineering in 1991. Since then, Design Engineering has built an impressive list of clients and delivered a diverse range of engineering services. A restructure in 2021 created the DE Group with 3 separate entities. Under the DE Group each entity continues to provide innovative methods and solutions to the industry.
