Diploma in Weber/SU/Solex Carburettors: Rebuilding and Tuning — studying from New Zealand
Regulation, safety and reliability engineering is well established in New Zealand, underpinned by a strong regulatory framework for health and safety, transport, building and electrical equipment. WorkSafe New Zealand administers workplace health and safety law, while Standards New Zealand develops and publishes national standards. Professionals in this area support compliance, certification and risk assessment for manufacturers, infrastructure operators and public agencies.
Fees for New Zealand: NZ$2,160 (New Zealand dollar), with instalments and employer sponsorship available.

Questions from New Zealand
Which New Zealand bodies set the rules for safety and compliance engineering?
WorkSafe New Zealand regulates workplace health and safety, and the NZ Transport Agency Waka Kotahi handles vehicle and transport compliance. Engineering New Zealand is the professional body, including the Chartered Professional Engineer pathway. SEIUM's qualifications are private and not accredited by any national body, so their recognition is decided by employers or the relevant body.
Do New Zealand employers hire RAMS and safety engineers?
Yes. Reliability, availability, maintainability and safety roles exist across infrastructure, energy, transport, and manufacturing. Employers typically look for demonstrated competence against recognised standards and professional registration where relevant. A private qualification can support an application, but employers decide how much it counts.
Can I study this alongside work, and do I need a visa?
Yes to both parts. The programme is 100% online and taught in English, so no student visa is needed to study from New Zealand. You get an assigned technical tutor and complete a final project. Fees are payable in instalments, and employer sponsorship is possible. Programme lengths range from 300 to 1,900 hours.

How you'll learn
100% online training on the SEIUM 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 work.
Each module combines theory, guided reading of the original standard and applied exercises. The working software is Innovate LogWorks, Autodata, Dynojet Power Core, Excel tuning sheets and Haynes Pro, in free, academic or evaluation versions. Testing is studied through real procedures for stripping and cleaning carburettors, lambda tuning on a rolling road and synchronising multiple chokes. Assessment is continuous by module, plus the final project.
Standards covered: EN 228, Directive 2009/30/EC and the FIVA Technical Code, together with historic vehicle and roadworthiness inspection regulations.
Build it end to end
Your final project follows the real engineering workflow, step by step, reviewed by your tutor.
