Camp Hamac in Sicayab, Dipolog City was named after the late LT. DIOGRACIAS G. HAMAC, a patriotic and courageous Filipino who fought during World War II to drive away from the Japanese invaders from Dipolog.

On October 1, 1945, the Zamboanga Provincial Military Police Command was established in Sicayab, Dipolog City by virtue of General Order No. 4.  Its provincial headquarters stood in this camp.

COL. LEODEGARIO C ORENDAIN was the first provincial commander who served from 01 October 1945 to 26 January 1946. He was succeeded by twenty provincial commanders who also served from 27 January 1946 to 30 September 1976.

On August 8, 1975, the Provincial Command was renamed Zamboanga del Norte PC/INP Command pursuant to PD 765.

The enactment of Republic Act 6975 merged the Philippine Constabulary and the Integrated National Police into one police organization – national in scope and civilian in character in compliance with the transitory provision of the 1987 Philippine Constitution. Thus, on January 1, 1991, the PC and INP eventually became the Philippine National Police.

The ZN-PC/INP Command was renamed Zamboanga del Norte Police Provincial Command. Seven provincial commanders were designated to head the command.

During the PNP reorganization in 1991, the title of the head of the Command was changed from Provincial Commander to Provincial Director because the Zamboanga del Norte Provincial Police Command was renamed Zamboanga del Norte Police Provincial Office.
