Marjory Stoneman Douglas students visit Christchurch

Twenty eight students from Marjory Stoneman Douglas High School in Parkland, Florida are arriving Christchurch this morning to spend a week with the Student Volunteer Army. The Parkland survivors are spending a week in New Zealand to share experiences with the Christchurch students and to learn how to sustain organisations once the public attention has waned. The president of the Student Volunteer Army, Josh Blackmore, talks to Philippa Tolley.
