The Coke Shake 30 Countdown was a radio show played in syndication across independently owned radio stations in New Zealand (and some ZM stations) during the early to mid 1990s.
Typically the countdown was pre-recorded during the week and played at various times on each individual station during the weekend.
Countdown data was taken from request and votes for local countdown shows during the week on each station as well as airplay and this information put together made up the hottest 30 songs for the week on New Zealand radio.
An extra to the show was a short segment by The Filth Man, this was the latest Hollywood gossip.
Stables Fat 40 Countdown which played on The Edge FM was syndicated to radio stations around New Zealand in regions where The Edge did not broadcast after The Power Jam Countdown ended.
