ZM (radio station)

ZM (/ˈzɛdɛm/ ZED-em) is a New Zealand Contemporary hit radio radio network owned by New Zealand Media and Entertainment. It broadcasts to 31 markets throughout mainland New Zealand via terrestrial FM, and worldwide via the Internet. The network targets the 18–39 demographic specialises in a chart-music playlist of pop, rock, hip hop, country and dance music. It reaches approximately 480,300 listeners weekly, making it the fifth largest commercial radio station in New Zealand.

The ZM network was founded in the early 1970s as three separate commercial music stations owned by Radio New Zealand in Auckland, Wellington and Christchurch. The name is derived from the former callsigns of the stations: 1ZM, 2ZM and 3ZM. The stations were transferred to The Radio Network (now merged into New Zealand Media and Entertainment) in 1996, and ZM expanded across the country, initially as three separate networks before merging to form one nationwide network in 2000.

The network's head office and main studios are based in Auckland, where all of the programming is produced.
