About Us

Contech (Construction Techniques Ltd) is a specialist civil construction contractor in New Zealand, focused on delivering complex infrastructure strengthening, repair, and remediation projects. The company operates across multiple regions, providing technical expertise and practical delivery capability for a wide range of civil and structural works, particularly within transport and infrastructure networks.
Contech’s core capability lies in the strengthening and rehabilitation of concrete structures, where it delivers targeted interventions to extend asset life and improve structural performance. These works commonly include concrete repair, crack injection, fibre-reinforced polymer (FRP) strengthening, structural steel repair and coating, and bearing upgrades. The company combines these services to deliver integrated solutions tailored to the condition and requirements of each asset.
A key strength of Contech is its ability to deliver highly specialised works in challenging environments, including state highways, bridges, and marine or remote locations. The company’s approach is grounded in detailed planning, staged construction methodologies, and strong coordination with clients, consultants, and subcontractors. Projects are often delivered under constrained conditions, such as live traffic environments or night work operations, requiring precise execution and careful staging.
