Administrative districts
Following the separation (on 18 December 2003) of this regency's then northern districts to create a separate North Kolaka Regency (Kabupaten Kolaka Utara), the Kolaka Regency was until 2013 divided into twenty districts (kecamatan). On 14 December 2012, the Indonesian Parliament approved the establishment of a new East Kolaka Regency (Kabupaten Kolaka Timur), and on 11 January 2013, under Law No. 8 of 2013, the nine eastern kecamatan were removed to form the new East Kolaka Regency, leaving the eleven western kecamatan in Kolaka Regency. A twelfth district (Iwoimendaa) has subsequently been added by splitting off the western villages of Wolo District.
The twelve districts are tabulated below with their areas and their populations at the 2010 Census and the 2020 Census, together with the official estimates as at mid 2025. The table also includes the location of the district headquarters, the number of administrative villages or subdisctricts in each district (totaling 100 rural desa and 35 urban kelurahan), and their post codes.
