Contech: The Engineered Concrete Specialists

Founded in 1963, Contech has established itself as New Zealand’s leading specialist civil engineering company. The key to our decades of success is our commitment to deliver a seamless experience for our customers.

Our concrete experts have extensive expertise in post-tensioning, seismic strengthening, structural upgrading and advanced concrete repairs. We have developed new methodologies and products, and partnered with leading civil engineering companies from around the world. Above all, we have invested in our design capability, and we make our project design assistance freely available to our clients to make their projects easy.

As masters of our industry, we support new knowledge and continual learning. Our involvement in research projects with the Universities of Auckland and Canterbury have explored post-tensioning and FRP (fibre-reinforced polymer) applications as retrofit solutions for earthquake resistance.

Quality and Safety Standards

Quality assurance and standards

Contech commits to meeting the highest standards of quality assurance, environmental management, and health and safety performance in our work. Our ISO9001 and ISO45000 certifications provide evidence of this commitment. Our safety management systems have been reviewed and accredited to Site Safe Gold, Impac PreQual and the SHE accreditation for Waikato and Bay of Plenty local authorities.

Global connections add strength

Contech is an active member of the BBR Network, a global group of engineering contractors that specialise in post-tensioning, ground anchoring, construction engineering and structural maintenance, repair and retrofitting.


With members having a presence in over 50 countries, the BBR Network enables us to access the knowledge and resources of some of the world’s most experienced and talented engineers and technicians. It also allows us to source the latest in European-approved and CE-marked construction systems and technology, many of which are exclusively provided by Contech in New Zealand. This helps us be at the forefront of technology in complex fields and customise it to meet client needs.
