Seasons are changing when it comes to secondary school sports.  In just over a year’s time, basketball is set to become the most popular sport, with participation jumping 61% since 2000.  However, there’s now concerns that New Zealand is 500 courts short to support the growing popularity.   School Sport NZ CEO Mike Summerell told Mike Hosking that while schools have great facilities they can only cater for the smaller games, and national competitions are maxing the current facilities out.  He says they also have to share the courts with other sports, and while they want the games to be played indoors, space is hard to come by.  LISTEN ABOVE  See omnystudio.com/listener for privacy information.
