Diploma in Fault Diagnosis in Gearboxes/Drives
Online postgraduate diploma of 800 hours in fault diagnosis of gearboxes and drives. 8 modules covering ISO 13373-1, ISO 13379-1 and ISO 15243:2017, with MATLAB Signal Processing Toolbox, Python with SciPy and SKF @ptitude Analyst, with an assigned technical tutor.
Diploma in Fault Diagnosis in Gearboxes/Drives — studying from New Zealand
Robotics and automation are increasingly important in New Zealand, especially in dairy processing, food manufacturing, forestry, horticulture and logistics. Research groups at the University of Auckland and the University of Canterbury lead in robotics and control engineering, and firms in these regions develop automated systems for primary industries. Engineers work on process control, industrial automation and robotic integration for manufacturers and technology providers.
Fees for New Zealand: NZ$2,550 (New Zealand dollar), with instalments and employer sponsorship available.

Questions from New Zealand
Which New Zealand bodies recognise robotics and control engineering?
Engineering New Zealand is the professional body, and the Chartered Professional Engineer pathway is the recognised route to professional status. Universities such as the University of Auckland and the University of Canterbury offer accredited engineering degrees. SEIUM's qualifications are private and not accredited by any national body, so their recognition rests with employers or the relevant body.
Do robotics and automation employers in New Zealand value this training?
New Zealand has demand for automation skills in dairy processing, food manufacturing, forestry, and advanced manufacturing. Employers generally value practical project experience and programming ability highly. A SEIUM qualification can strengthen a CV, but whether it counts is for each employer to decide.
Is the programme workable alongside a full-time job in New Zealand?
Yes. The programme is 100% online and taught in English, so you can study from anywhere in New Zealand without a student visa. Master's programmes total 1,900 hours, postgraduate diplomas 800 hours and specialist courses 300 hours. You have an assigned technical tutor, and fees are payable in instalments or sponsored by an employer where possible.

How you'll learn
Training is 100% online 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 job.
Each module combines theory, guided reading of the original standard and applied exercises. The working software is MATLAB Signal Processing Toolbox, Python with SciPy, Emerson AMS Machinery Manager, SKF @ptitude Analyst and the robot manufacturer's diagnostic software, in free, academic or evaluation versions. Testing is studied through real procedures: envelope and order analysis on variable-speed axes, current signature diagnosis of servomotors, and lubricant analysis and ferrography of gearboxes. Assessment is continuous by module, plus the final project.
Standards covered: ISO 13373-1, ISO 13379-1, ISO 15243:2017, ISO 10825-1, IEC 60034-27, ISO 4406:2021 and IEEE 43-2013.
