Our press release:
Press Release- John Brett Technology Ltd.
Are you sure your vehicle is safe? Are you sure it is legal for road use?
Any modified or scratch-built vehicle is required by law to have Low Volume Vehicle Certification to ensure that safety and environmental standards are met.
Warrant and COF agents are required to see an LVV Plate covering any modifications, before the WOF or COF can be issued. Insurers will decline insurance or claims for illegally modified vehicles. The NZ Police are happy to “Pink Sticker” any illegally modified vehicle, ordering it off the road.
John Brett Technology Ltd. is a “Low Volume Vehicle Certifying Organization”, under delegated authority from the Land Transport Agency.
John will
- Provide advice and information on vehicle modification.
- assist with the design, construction and modification of vehicles,
- carry out the required inspections, and
- Issue an official “Low Volume Vehicle Certification plate” which shows that the vehicle now meets the standards required.
John Brett Technology works with
- new vehicle franchises,
- used vehicle Importers,
- seatbelt specialists,
- mini-bus and wheelchair van constructors,
- disability adaption specialists,
- classic car enthusiasts,
- Professional and amateur vehicle modifiers of all types.
Example – a performance car enthusiast may want to fit a bigger engine, modified suspension, different wheels and tyres, big exhaust, etc. John has to ensure that the finished vehicle drives handles and brakes to the required standard, and meets the exhaust emission and noise standards.
Example -mini-buses and wheelchair taxis: A 50 K.P.H. collision is equivalent to a 3 story drop to the ground. The seats, seatbelts, and wheelchair restraints all have to protect the occupants from injury. John will help design the installation and supervise the construction.
Example- a classic car enthusiast will now be required to fit seatbelts to any vehicle later than 1955. John can engineer a seatbelt system to provide safety, with minimal affect on the original appearance of the vehicle.
The friendly, helpful and knowledgeable staff of John Brett Technology Ltd. is ready to answer your call.

Hi Bob
From the NZTA website http://www.nzta.govt.nz/vehicle/classes-standards/class.html Your trailer is Class TB, light trailer. Surprisingly there is NO Certification requirements for this class- the only requirements are for the WOF inspection.
I have seen some appallingly dangerous trailers built and put onto the road, without any form of Engineering Inspection other than the WOF. From what you say of your qualifications and experience, you should be able to do an excellent job, and there is no special inspection required.
