This weekend Otaki 's skies are filled with works of art - kites that have taken their creators many hours to build and decorate. They include flying canvases by one of Australasia's most famous kite makers, Tony Rice. Tony's a regular visitor to the Otaki Kite Festival, and he's taking workshops to encourage more people to take up kite making - something he says is struggling to attract young people. Tony's a traditionalist in his choice of materials, and, as he tells Lynn Freeman, he's increasingly using his kites to spread the word about plastic pollution and the harm it's causing marine life.
