CBC Radio programming first aired in Fredericton on private affiliate CFNB 550.
CBC's own station launched on March 4, 1964 as CBZ at 970 on the AM band. Provincial Premier Louis Robichaud and Don Messer's troupe were on hand for the opening ceremonies which originated from the Lord Beaverbrook Hotel.
In 2004, CBZ moved to the FM band on 99.5 MHz. The call sign was changed to CBZF-FM as CBZ-FM was already used by the Radio 2 sister station.
CBZF-FM currently produces a local morning news and current-affairs program, Information Morning, which airs weekdays from 6:00 a.m to 8:37 a.m. on CBZF-FM. CBZF-FM also produces news & weather updates which are heard throughout the province weekdays between 9 a.m. and 6 p.m. Information Morning is also simulcasted via CBAT-DT to the entire province. The program is called New Brunswick First and airs Monday to Friday from 6 a.m. to 8 a.m. on CBAT-DT. CBAT-DT is the only CBC-owned and operated affiliate that produces this kind of simulcast. CBZF-FM also produces the provincial afternoon show Shift, which airs between 4 p.m. and 6 p.m. weekdays.
