Each day we live our lives through a progression of journeys. Whether by car, bus, train, ferry, cycle or on foot, our journeys begin and are realised on an intricate network of road, rail or paths linking departure to arrival.

TDG is New Zealand’s largest specialist transportation engineering consultancy offering a full range of professional services in transportation: engineering, planning, modelling, analysis and design. With offices throughout the country, our work spans large and small developments, in both the private and public sectors. Wherever people and transportation meet, that's where we are. Making that meeting point better, is what we do.
