The country was broken into five fire regions: Region 1 (Northland/Auckland), Region 2 (Waikato/Bay of Plenty/Gisborne), Region 3 (Lower North Island), Region 4 (South Island north of the Waitaki River), and Region 5 (South Island south of the Waitaki River). Each region was in the charge of a Fire Region Commander. All FRCs report directly to the National Commander, and were promoted from the ranks of operational staff. A FRC could take control of a major incident, and was ultimately responsible for any incident at which they are present even if they were not the Officer-in-Charge.
