2ZG was a radio station in Gisborne originally owned by the Radio New Zealand commercial operation. The station was first started as 2XG in 1948 broadcasting on 1010AM. In the 1960s the call sign and brand name were changed to 2ZG and the station moved to 1060AM. In 1978 after New Zealand changed its AM frequency spacing from 10 kHz to 9 kHz 2ZG moved to 945AM.
2ZG was known as The Coaster during the 1980s and in the 1990s as Gisbornes 2ZG. In 1996 Radio New Zealand sold their commercial operation and as a result 2ZG was now owned by The Radio Network. In 1998 2ZG became part of the Community Radio Network with all content outside breakfast now being fed from Taupo. In 1999 2ZG began broadcasting on 90.9FM and as a result the station was renamed to ZGFM. In early 2001 the original 945AM frequency was reassigned to Newstalk ZB and at the end of 2001 all Community Radio Network stations became part of the Classic Hits network, as a result ZGFM became known as Classic Hits 90.9 ZGFM with all programming outside of breakfast now fed from the Classic Hits studio in Auckland.
Today the station is known as Classic Hits 90.9 and the local breakfast show is hosted by Darryl Mallett.
