The New Zealand FP/FT "Matangi" class[4][5] (/ˈmɑːtʌŋi/) is a class of electric multiple units used on the suburban rail network of New Zealand's capital city, Wellington. The class, consisting of an FP power car and an FT trailer car, operates services on all electrified lines of the network which comprise the Kapiti, Hutt Valley, Melling and Johnsonville lines. The units are owned by Greater Wellington Rail Ltd,[3] a subsidiary of the Greater Wellington Regional Council (GWRC), and have been operated by Transdev Wellington under contract to the GWRC since 2016. They were previously operated by Tranz Metro, a former division of KiwiRail.

The FP/FT units were built in South Korea by a consortium of Hyundai Rotem and Mitsui, with the first unit arriving in New Zealand in July 2010 and entering full-time service in March 2011. The first batch of 48 units, the 4000 series units, allowed an increase in the capacity of the Wellington network, and allowed the retirement of the ageing DM/D class "English Electric" multiple units that were introduced between 1949 and 1954. The 4000 series also relegated the EM/ET "Ganz-Mavag" class multiple units (introduced 1982-83) to peak services only. A second batch of 35 units, the 5000 series, were introduced in 2015–16 to replace the remaining EM/ET units.
