What Is a Light Trailer?

A light trailer is simply a trailer used to transport goods, equipment, machinery or recreational load and its use is usually personal, commercial and industrial. Light trailers in New Zealand have specific requirements in terms of design, construction and compliance with regard to their intended use and loaded weight.
Professional light trailer engineering New Zealand services may be required when designing a new trailer, modifying an existing trailer or seeking certification for registration and compliance purposes. Engineering assessments are used to test that trailers are fit to use and comply with safety standards.

Common Light Trailer Types:

  • Box trailers
  • Car trailers
  • Plant and equipment trailers
  • Tradesperson trailers
  • Tiny home trailers
  • Custom-built trailers

Key Weight Definitions

  • Tare Weight: This is the weight of the empty trailer.
  • ATM (Aggregate Trailer Mass): The maximum permissible loaded weight of the trailer.
  • Payload Capacity: The maximum weight that the trailer can carry.
Whether you're building a new trailer, upgrading components or seeking a trailer engineering certificate New Zealand, engineering support can assist with design verification, compliance documentation and certification requirements.
