The New Zealand EM/ET class (also known as Ganz-Mavag) electric multiple units were used on suburban services in Wellington, New Zealand from 1982 to 2016. They were owned initially by the New Zealand Railways Corporation and finally by the Greater Wellington Regional Council (GWRC) and operated by Tranz Metro, part of national railway operator KiwiRail.[3]
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 In 2012, the GWRC ordered a second batch of Matangi units to replace the Ganz-Mavag units, and the last units were withdrawn from revenue service on 27 May 2016 after 34 years in service.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.
