Online master's programme of 1,900 hours in resonant and high-frequency converter engineering: 12 modules covering resonant circuit theory, LLC and CLLC converters, GaN and SiC devices, high-frequency magnetics, control, PCB parasitics, EMC and wireless power transfer, with an assigned technical tutor.
Master’s in Resonant and High-Frequency Converters Engineering — studying from New Zealand
Electronics and telecommunications are significant New Zealand industries, with Chorus operating the national fibre network and Spark, One NZ and 2degrees providing mobile services. Embedded systems and electronics design are strong in Auckland, Christchurch and Wellington, serving agricultural technology, medical devices and industrial automation. Engineers in this field work for telecommunications providers, electronics manufacturers and research groups, and the Radio Spectrum Management team within the Ministry of Business, Innovation and Employment oversees spectrum use.
Fees for New Zealand: NZ$17,700 (New Zealand dollar), with instalments and employer sponsorship available.

Questions from New Zealand
How do New Zealand bodies recognise electronics and telecom engineers?
Engineering New Zealand is the body for engineering registration, including Chartered Professional Engineer status. Telecommunications is overseen by the Commerce Commission and the Ministry of Business, Innovation and Employment, and radio spectrum is managed by MBIE. SEIUM's qualifications are private and not accredited by a national body, so employers decide their weight.
Which New Zealand employers hire embedded systems and telecom engineers?
Employers include telecommunications operators, electronics manufacturers, device makers, defence and aerospace suppliers, and research institutions. Hiring often prioritises practical embedded work, firmware projects and certifications relevant to the role. A private online qualification may help your application, but it does not guarantee an offer.
Is this manageable online from New Zealand, and what study load should I expect?
The programmes are online and in English, so no student visa is needed to study from New Zealand. Each has an assigned technical tutor and a final project. Specialist courses are 300 hours, postgraduate diplomas 800 and master's programmes 1,900. Fees can be paid in instalments, and employer sponsorship is possible, so check funding options first.
