The 44 two-car units of an EM motor car and an ET trailer car were introduced between 1982 and 1983 on the 1500 V DC electrified Kapiti, Hutt Valley and Melling lines. After the introduction of the Matangi FP/FT class EMUs in 2011–12, they were largely relegated to peak services only. In 2012, the GWRC ordered a second batch of Matangi units to replace the Ganz-Mavag units, and the last units were withdrawn from revenue service on 27 May 2016 after 34 years in service.
The name "Ganz-Mavag" comes from the units' manufacturer, Ganz-MÁVAG of Hungary. It was widely used by the GWRC and in the media to distinguish them from other electric multiple units used on the Wellington suburban lines; they were also referred to as Hungarian units.
