Bay City Radio was a radio station in Napier, New Zealand. The station was started by Radio New Zealand (which at the time was known as the National Broadcasting Service) on 1 October 1957 using the call-sign 2ZC and broadcasting on 1280 kHz AM. On air the station was branded as its callsign 2ZC with the slogan Twin-City Radio as the station served both Napier and Hastings. In 1977 Radio New Zealand started a second station called Apple Radio. When Apple Radio commenced as a stand-alone station from the previously shared Hastings studio, 2ZC was re-branded as Bay City Radio.
