HUTEC provides shut and project management, design, CNC machining, mechanical, electrical and instrumentation maintenance expertise to our customers in geothermal and hydro power generation, pulp and paper, wood products and processing, dairy, fertiliser processing and others.

Our brand may be relatively new, but we have grown our team with the best people in industry, assembled a wealth of experience and successfully delivered over 100,000 hours of mechanical, electrical and instrumentation maintenance solutions to our customers, from our bases in Kawerau, Whakatane and Taupo.

Technical (tricky) work is our specialty; whether it’s reverse engineering 40-year-old pulp and paper equipment to perform better than new or managing sixty-plus trades people to complete dozens of complex tasks during a 24 hour shut window, nothing is too challenging – plus all work is completed transparently, so customers can see where every hour and dollar is captured (after all our motto is “Engineered Transparency”).

We also believe in investment in Kawerau and are currently building a large refurbishment workshop at 2 Manukorihi Drive; similarly, we recognise that our people are our greatest asset and we currently employ and train apprentices from the wealth of talent in the local community.
