About TRT - Tidd Ross Todd

Overcoming challenges is precisely how this business got started in 1967. Clever people solving complex engineering problems with ingenuity, and relentless hard work. 

It's this competitive ethos of solving the unsolvable, finding a way, and just getting on with it, that helps us make things possible for our customers. 

Making things possible means choosing the better problem to solve, out thinking it, and then by sweating every single detail until it's done, made and, delivered. 

Tidd Ross Todd Ltd (TRT) is a privately-owned, family business, specialising in the design, manufacture, sales and delivery of products and services within New Zealand and Australia’s road transport and construction industries.
