300-hour online course in varnishes for classic interiors. 6 modules covering Directive 2004/42/EC (volatile organic compounds in paints and varnishes), Royal Decree 227/2006 (VOC emissions from paints and varnishes) and advanced Excel. Assigned tutor and open enrolment.
Varnishes for Classic Interiors Course — studying from New Zealand
Vehicle restoration and classic engine work in New Zealand is supported by an active enthusiast community and a well-established network of specialist workshops, particularly around the main centres. Historic vehicle registration and compliance fall under the New Zealand Transport Agency Waka Kotahi, and the Vintage Car Club of New Zealand promotes preservation of historic vehicles. Restoration professionals often combine fabrication, engineering and heritage conservation skills.
Fees for New Zealand: NZ$1,470 (New Zealand dollar), with instalments and employer sponsorship available.

Questions from New Zealand
Is restoration engineering recognised by a professional body in New Zealand?
There is no specific statutory register for classic vehicle or heritage restoration engineers in New Zealand. Heritage matters can involve Heritage New Zealand Pouhere Taonga, and vehicle roadworthiness is governed by the NZ Transport Agency Waka Kotahi. SEIUM's qualifications are private and not accredited by any national body, so their value depends on the employer or client.
Where do classic restoration specialists work in New Zealand?
Work is found in independent restoration workshops, classic car dealers, museums, and specialist fabrication businesses, many clustered around the main centres. Clients and employers usually judge by workmanship and a portfolio of completed restorations. A private qualification may complement that evidence but is rarely a deciding factor on its own.
Can I study this while running or working in a workshop here?
Yes. The course is fully online and taught in English, so you can study from home in New Zealand without a student visa. Specialist courses total 300 hours, postgraduate diplomas 800 hours and master's programmes 1,900 hours. An assigned technical tutor supports you, and fees can be paid in instalments.

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: students progress at their own pace within the intake, which makes it possible to combine the course with work.
Each module combines theory, guided reading of the original standard and applied exercises. The working software is Advanced Excel, X-Rite Color iQC, Adobe Lightroom, Airtable, in free, academic or trial versions. Tests are studied using real testing procedures: cross-cut adhesion testing, gloss measurement with a gloss meter, and varnish application in a spray booth. Assessment is continuous by module, plus the final integrative project.
