CBC Radio programming first aired in Fredericton on private affiliate CFNB.
CBC's own station launched on March 4, 1964 as CBZ at 970 AM. Provincial Premier Louis Robichaud and Don Messer's troupe were on hand for the opening ceremonies which originated from the Lord Beaverbrook Hotel.
CBZF currently produces a local morning news and current-affairs program, Information Morning, which airs weekdays from 6:00 a.m. to 8:30 a.m. on CBZF. CBZF 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. CBAT is the only CBC-owned and operated affiliate that produces this kind of simulcast. CBZF also produces the provincial afternoon show Shift, which airs between 4 p.m. and 6 p.m. weekdays.
On September 1, 2017, the CBC applied to convert CBAX 600 to 95.5 MHz. The new callsign will be CBZF-FM-1. CBAX is currently the last low-power AM transmitter to rebroadcast CBZF-FM and also the last low-power CBC AM transmitter in the province. The CRTC approved the CBC's application to move CBAX to 95.5 FM on November 3, 2017.
