Postgraduate Diploma in Digital Filtering, Artefact Detection and Signal Quality — studying from New Zealand
Health engineering in New Zealand covers medical devices, biomechanics, rehabilitation technology and occupational safety, with significant activity in Auckland, Wellington and Christchurch. The Medsafe regulator within the Ministry of Health oversees medical device approval, and the Accident Compensation Corporation plays a central role in workplace injury prevention and safety. Biomechanics research is supported by university groups and by the country's strong sports science community.
Fees for New Zealand: NZ$2,960 (New Zealand dollar), with instalments and employer sponsorship available.

Questions from New Zealand
Will this qualification be recognised by Engineering New Zealand in New Zealand?
Engineering New Zealand is the professional body for engineers here and runs the Chartered Professional Engineer (CPEng) pathway. SEIUM's qualifications are private qualifications, not official state degrees, and are not accredited by any national body. Recognition for any purpose is decided by the employer or the relevant body, so check with them before relying on it for registration.
Would a biomechanics or wearables background help me find work in New Zealand?
Interest in wearables and workplace safety exists across New Zealand's health technology, rehabilitation, sport science and occupational health sectors. Whether an employer values a SEIUM qualifications depends on the employer's own assessment of your skills and experience. A portfolio of applied projects is often what carries the most weight in hiring decisions.
Can I study this while working full time in New Zealand?
Yes. The programme is fully online and taught in English, so you can study from anywhere, including from home, and you do not need a student visa for that. Master's programmes total 1,900 hours, postgraduate diplomas 800 hours and specialist courses 300 hours, with an assigned technical tutor. Fees can be paid in instalments, and employer sponsorship is possible.

How you'll learn
100% online training on the SEIUM campus, with downloadable material, recorded classes and an assigned technical tutor. No fixed timetables: students progress at their own pace within the intake, which makes it possible to combine study with work.
Each module combines theory, guided reading of the original standard and applied exercises. The working software is MATLAB (Signal Processing Toolbox), Python (SciPy, MNE), PhysioNet WFDB, EEGLAB, in free, academic or trial versions. Tests are studied using real processing procedures on PhysioNet databases, recording signals with controlled artefacts, and validating algorithms against reference annotations. Assessment is continuous per module plus the final integrative project.
Build it end to end
Your final project follows the real engineering workflow, step by step, reviewed by your tutor.
Describe the characteristics of the main biomedical signals.
Design FIR and IIR digital filters for physiological signals.
Apply adaptive filtering to remove interference.
Detect motion and electrode artefacts.
Calculate signal quality indices.
Where this takes you
