Why GT
Four reasons GT Trailers are built differently.
Built Tough for NZ Roads
GT Trailers use welded steel and tread-plate construction with laminated marine plywood decking — built for real New Zealand towing and site conditions, not just showroom loads.
Hot-Dip Galvanised Finish
Every GT trailer is fully hot-dip galvanised, not just painted — giving genuine long-term corrosion resistance for New Zealand's coastal and rural conditions.
A Range for Every Job
From contractor trailers built for daily tradie use to heavy-duty digger trailers with hydraulic override braking, GT covers a wide range of site and load requirements.
Engineered for Safety
Hinged tailgates and perimeter tie hooks as standard, plus hydraulic override disc braking on our digger models — engineered around real load safety, not just cost.
