The number of teenagers participating in organised sport is decreasing, a move which reflects an overall drop-off in participation once teenagers left high school.

Gyms have replaced traditional sports like Rugby and Cricket to be the most popular form of exercise amongst teenagers.

"Sport New Zealand needs to broaden its view of participation, if it included people who went to gyms the number would be a lot higher."
