Diploma in Heavy-Duty Braking Energy Recovery — studying from New Zealand
Off-road and special vehicle engineering is a major strength in New Zealand, reflecting the importance of agriculture, forestry, mining and construction. Manufacturers and fabricators in the Waikato and Canterbury produce tractors, harvesters, dairy equipment and specialised machinery, many of which are exported worldwide. Engineers in this field work on design, testing and safety compliance for equipment used on farms, in plantations and on remote worksites.
Fees for New Zealand: NZ$2,550 (New Zealand dollar), with instalments and employer sponsorship available.

Questions from New Zealand
Which New Zealand bodies relate to off-road and specialist vehicle engineering?
Engineering New Zealand is the main professional body, and vehicle compliance is handled by the NZ Transport Agency Waka Kotahi. Heavy machinery and certain specialist vehicles can also fall under WorkSafe New Zealand rules. SEIUM's qualifications are private and not accredited by any national body, so employers and regulators decide their value.
Who hires off-road and special vehicle engineers in New Zealand?
Employers include forestry and agricultural equipment firms, mining and civil construction contractors, fabrication shops, and emergency or utility vehicle fleets. Practical design, safety and maintenance skills are central to hiring. A SEIUM qualification may help, but its weight depends on the employer.
How does the study load work for someone with a job here?
The programme is fully online, so you can study around work from anywhere in New Zealand without a student visa. Specialist courses take 300 hours, postgraduate diplomas 800 hours and master's programmes 1,900 hours. You get an assigned technical tutor, and fees can be paid in instalments or sponsored by an employer.

How you'll learn
Training is 100% online on SEIUM's campus, with downloadable material, recorded classes and an assigned technical tutor. There are no fixed timetables: you progress at your own pace within each intake, so the programme fits around your job.
Each module combines theory, guided reading of the original standard and applied exercises. The working software is MATLAB/Simulink, Simcenter Amesim, GT-SUITE and AVL CRUISE M, in free, academic or evaluation versions. Exercises are based on real procedures for measuring recovered energy on quarry descents, simulating regenerative brake blending and bench thermal tests of brakes. Assessment is continuous by module, plus the final capstone project.
Standards covered: UNECE Regulation R13, ISO 3450, ISO 6469-3, ISO 19014, UNECE Regulation R100, Machinery Directive 2006/42/EC.
Build it end to end
Your final project follows the real engineering workflow, step by step, reviewed by your tutor.
