Whatever you’re hauling, there’s a Trade Tested trailer for sale to match your needs. Our range is designed for real Kiwi jobs, from backyard projects to light commercial work.
Single axle box trailers
A strong, all-round option for home and trade use. Available in 7x4 ft and 8x5 ft bed sizes, each heavy-duty trailer supports up to 500 kg, making them ideal for weekend clean-ups, garden projects, or moving tools and equipment.
Box trailers with cages
Our caged trailers offer great versatility for bulkier or awkward cargo. The removable cage and forward/rear doors make loading and unloading easy, whether you’re shifting fencing materials, branches, or farm supplies.
Flatbed trailers (optional configuration)
Perfect for items that don’t fit inside a box frame—like timber, equipment, or furniture—offering full bed access and easy strapping points for secure transport.
All our heavy-duty trailers are easy to tow, stable on the road, and engineered for simple connection to standard tow balls. Pair your setup with PVC cage covers, spare wheels, or jockey wheels for a complete, road-ready solution.

Towing & maintenance tips
Keep your heavy-duty trailer in top shape and enjoy safer, smoother towing with these tips.
Match your trailer to your vehicle’s towing capacity. Always check the weight rating in your car or ute manual.
Before each trip, inspect tyre pressure, lights, hitch, and safety chain.
Distribute weight evenly across the bed to prevent sway and keep heavier items centred.
After use, rinse away mud or salt to maintain corrosion protection.
Lubricate hinges and jockey wheels regularly, and touch up any worn areas with galvanising spray.
For all-weather reliability, add a PVC cover to shield your cargo from rain and road debris.

Frequently asked questions
How do I pick the right trailer size?
For everyday hauling, a 7x4 ft trailer suits most tasks. If you regularly move larger or heavier cargo, consider upgrading to an 8x5 ft trailer.
Can I tow a trailer with a standard car?
Yes, most cars and utes can tow our single-axle trailers. Always confirm your vehicle’s towing limit and ensure your tow bar, electrics, and safety chain are correctly fitted.
What’s the difference between single and tandem axle trailers?
A single-axle trailer is lighter and easier to manoeuvre, making it perfect for home and light trade use. A tandem-axle trailer, often used for construction or landscaping, handles heavier loads with greater stability.
How do I maintain my trailer for long-term use?
Keep your trailer clean, inspect it regularly, and lubricate moving parts. Avoid overloading and store it under cover when not in use to extend its lifespan.
Are these trailers suitable for New Zealand weather?
Yes. Each Trade Tested heavy-duty trailer features a galvanised steel frame that withstands NZ’s rain, UV exposure, and coastal air, providing fantastic protection and reliability long-term.
Do the trailers come with lights and meet road-legal requirements?
Yes, all Trade Tested trailers are designed to meet NZ road standards; you can easily register your trailer at the VTNZ next to our Auckland store. Lights and reflectors are included where required.
