Practical Solutions, Built Smarter

At Ten4, good design isn’t about making things complicated—it’s about making them work better.

Our in-house design and engineering team specialises in creating practical, creative solutions tailored to your real-world needs.

Whether you’re starting from a sketch on a napkin or upgrading an existing fleet, we design smarter, build tougher, and make sure every detail serves a purpose.

Creative Solutions for Tricky Problems

Got a challenging project? That’s where we shine. We’re known for designing custom transport and fabrication solutions that others can’t—or won’t—take on. From unique gear racks to specialty bins, from tricky load-outs to integrated tool storage, if it needs thinking outside the box (and building like it matters), you’re in the right place.

Custom Designs That Fit Your Needs

No two jobs are the same, and neither are our designs. We work closely with you to understand your operation, then create custom solutions that are:

  • Fit-for-purpose

  • Built to spec

  • Compliant with NZTA and industry standards

  • Ready for the real work you do

From chassis layouts to hydraulic systems, load capacities to tie-down designs, everything is engineered to perform—not just to look good.

Engineering That Gets It Right, First Time

Our team handles all aspects of the engineering process:

  • Structural design and load calculations

  • Hydraulic, electrical, and mechanical integration

  • Material selection to match strength, weight, and wear needs

  • NZTA certification preparation and approvals

We design with buildability and longevity in mind, meaning less downtime, fewer modifications, and trucks that just get on with the job.
