There was seven participating teams in the 2018 Under-19 Provincial Championship. They played each other twice during the
pool stage, once at home and once away. Teams receive four points for a win and two points for a draw. Bonus points were awarded to teams that scored four or more tries in a game, as well as to teams that lost a match by seven points or less. Teams were ranked by log points, then points difference (points scored less points conceded). The top four teams in the pool stage qualified for the
semifinals, which were followed by a
final. ==Teams==
