We are an independent and recognised specialist, all-purpose engineering company located in Auckland and Northland. We are frequently called on to review the work of other engineers and consultants thanks to our practical approach and thorough knowledge as well as rigorous analysis, fact-based risk management and focus to deliver solutions that are fit for all-purpose, constructible and durable.

At GRIT Engineering, we don’t do can’t. “OWN THE CHALLENGE” is our motto and we live by it. If it is tough, high risk and challenging we want to hear about it.  Every engineering problem has a solution and we specialise in finding ways to assess, modify, maintain and build industrial and infrastructure assets that save our clients’ money (fit for all-purpose, smarter, safer, sustainable).

We walk the talk every time and are all about adding value in our areas of expertise where we are genuinely qualified and experienced: civil structural engineering and design, durability and rehabilitation, asset management and coatings corrosion protection engineering.

What are we here for? Sustainable infrastructure for NZ’s future generations.

What our clients say

  • GRIT Engineering provided structural and durability engineering services with an investigation at Semenoff stadium. The stadium is an important asset for the Whangarei District, availability for large events and public safety are paramount. We found them to be very professional, responsive and competent. It felt we were in safe hands as GRIT engineers were practical and clearly focused on adding value. We would recommend GRIT for structural engineering and assessment projects on this basis.

  • As contractors on various industrial sites across NZ, we have enjoyed a close collaborative working relationship with Jason and his crew at GRIT. Recently we have engaged with GRIT for subject matter expertise both for structural as well as coatings scopes and make no hesitation in recommending the services and technical know-how offered by Jason and the team at GRIT.
