In 1969 Fraser & Thomas Engineers from Papatoetoe and Jackson Gunman & Partners, a surveying company in Otahuhu since 1947, merged to create a highly experienced and multi-disciplinary agency.

Fraser Thomas Gunman Shaw & Partners was situated at 152 Kolmar Road in Papatoetoe initially a freestanding house that was developed over the years to form the offices as they exist today.

By the 1980’s Fraser Thomas had expanded into Asia and the Pacific adding an office in Cambodia. Geotechnical Engineering was also introduced as a new service considerably increasing their expertise.

Fraser Thomas purchased Barry Satchell Consultants in 1991, a medium sized surveying company based in Epsom. Adding Civil Engineering and Planning to their core services allowed Fraser Thomas to directly service Central Auckland.

We have come a long way since 1969, and now offer incredible experience and expertise across a broad range of services both in NZ and overseas.
