'alternative music choice to the top 40-based formats offered by the private stations and was originally hosted by Barry Jenkin from Auckland. With his departure in 1983, the alternative format remained, but the music played was more top-40-based with the large percentage of NZ music. In 1987 with 1ZM dropping the ZM brand name The ZM All Nighter became known as "The All Nighter" on all stations. In 1989 The All Nighter was discontinued and stations that previously took this show now ran local shows or an automated show with no announcer. Auckland 1ZM becomes Classic Hits In 1982, 1ZM Auckland lost its bid for an FM license and with the Broadcasting Tribunal allowing two new private radio stations (Magic 91FM and 89 Stereo FM) into the Auckland market, 1ZM was required to re format and adopt a 'Limited Sponsorship' model in place of its full commercial licence. This was an attempt to assist the new operators in establishing a revenue base. For 1ZM this meant that although the station could still run paid-for advertisements, those messages could not have music underneath, mention price or be longer than 25 words. Within 2–3 years, both 1ZM's financial and audience market share dropped significantly as advertisers and young listeners were attracted by the higher quality sound of the FM stations, despite the absence of long commercial breaks on 1ZM. 1ZM at the time promoted itself as "Total Music ZM" to emphasise the limited commercial format. By 1987 1ZM Auckland was still a limited commercial station. A decision was made to change the format of 1ZM from a Contemporary Hit Radio format to a Classic Hits format. The Auckland station was rebranded as Classic Hits Twelve 51 which subsequently marked the birth of the Classic Hits brand which would be rolled out across New Zealand years later. In 1989 Auckland's Classic Hits Twelve 51 was finally given a licence to broadcast on FM and broadcast commercials. The station launched on 97.4FM as Classic Hits 97FM. The 1251 kHz frequency licence was transferred to Christian broadcaster Radio Rhema. In 1993 the format of Classic Hits 97FM was rolled out across New Zealand with local stations operated by Radio New Zealand taking on the same format and branding, ultimately all these stations became the Classic Hits network in 2001, and later The Hits network in 2014.
