In a meeting this week, it was decided that the knockouts competition will be held at the Arorangi courts on Saturday. The games will start at 11am. The open games were held last night.
Netball Cook Islands general secretary Ngere Puia-Fraser said the knockout competition required a winner, adding there was a procedure for extra time to determine the outcome of the match, if it ended in a draw.
“There shall be a two-minute interval at the end of full time. Extra time shall consist of two halves of seven minutes each, with an interval of one minute at half time,” Puia-Fraser said.
“Teams shall change ends at half time. The centre pass is taken by the team entitled to the next centre pass. During both of these intervals, substitutions and/or team changes may be made.
“In the event of a tie remaining at the end of extra time, a visual signal shall be used to indicate that play shall continue until one team has a two-goal advantage.”
For age group teams, 2 x 5 minute halves of extra time will be played while the senior teams will play 2 x 7 minute halves.
Players are also required to remain in the same team during the knockout competition. The flexibility rule no longer applies, Puia-Fraser added.
“Only players who played in the round can play in the knockout.”
Other rules include “if a player is on the team list for the 17 and under grade (example) and this team losers/knocked out … players who took the court are deemed to have played. Players who did not take the court may continue to play but only in a higher grade.”
