Radio New Zealand is compiling a playlist of around 2000 tracks but has rejected concerns it will be dropping its usual quirky and eclectic music in programmes like Nine to Noon and Kim Hill's Saturday Morning show.
Playlists are commonly associated with commercial radio.
The change follows a slump in National radio ratings that the broadcaster attributed to the speed of change in the past year.
The rating slump led to the chief executive Paul Thompson saying RNZ would look to slow change this year.
National Radio is mainly talk and the playlist move mostly affects the overnight programme which has an elderly following.
