World Rugby Officiating : The home of Rugby officiating on the web : Technical Zone Programme


It is the objective of the officials in the Technical Zone (TZ) to service both teams and to manage all aspects of replacements and substitutions in accordance with the TZ protocol ensuring compliance with the Laws of the Game.

This protocol is designed to ensure:

  • Correct information and action
  • Clarity and speed of communication

Technical Zone Officials (TZOs) need to have knowledge of the Laws of the Game, the TZ protocol itself and need to have interpersonal skills to manage the two teams during a match.
