Call sign Format

With the exception of Counties Manukau and Bay of Plenty police districts, who operate a different system, unit call signs follow this format:

  • Two characters: indicating the home station, beat area or district in which the unit primarily operates.
  • A character indicating the unit type.
  • Up to three characters which uniquely identify the unit.

In the Counties Manukau and Bay of Plenty police districts, unit call signs are five characters in length and follow this format:

  • Two characters that identify the geographical area of responsibility.
  • A letter and digit that identify the unit type.
  • Unique identifier of the unit: Digit = supervisory/NCO level and above; Letter = others.


  • TNI3 Takapuna I-Car (general duties), late shift.
  • SVM1 Auckland Motorways motorcycle unit, section 1.
  • CMT8C Counties Manukau serious crash unit officer.
