Originally an FM repeater for Wellington's 2ZB (89.8FM) in the early 1990s, the station was then relaunched as 'Goodtime Oldies B90FM' which also broadcast to the Kapiti Coast on 89.4. The station ran a 60s and 70s music format which originated from the Wellington studio and took no network programming. Around 1996, B90FM became 'Classic Hits 90FM' and an adjustment was made to the station's frequency, shifting from 89.8 to 90.0FM. Unlike the rest of the Classic Hits network, 90FM ran with a "60s, 70s and 80s" format, whereas all other Classic Hits stations (with the exception of Auckland and Christchurch) were playing "70s, 80s and 90s". Programming continued to originate from Wellington until 1998 when local shows succumbed to network programming. The Kapiti Coast repeater was eventually dropped and replaced with Newstalk ZB. On 27 October 2010, the station shifted frequencies to 90.1FM, to comply with Government broadcasting regulations.
