Company Accreditations

Geotech is proud of its staff, equipment and resources, and the services we can provide to clients. To help support us in providing quality products and services, we have committed to a number of accreditations, to help ensure that we are continually adapting and improving what we do.

NZTA – Construction 4A

Geotech are prequalified with NZTA, having been assessed under NZTA’s ISNetworld system. The process involves completion of a health, safety, environmental and quality questionnaire, and evidence of a range of business systems, staff competency and accreditations. Classification 4A enables us to tender for technical complex/specialist works, as well as works that are considered high risk or have complex and sensitive environmental management issues.
