A Canterbury University student who led earthquake recovery efforts in Christchurch is heading to help in Nepal following Tuesday's quake.
Sam Johnson, leader of the Student Volunteer army in 2011, said he was returning to the devastated country to help rebuild school classrooms in remote Himalayan villages.
"The concern from the village locals is that if we don't get schools operating again soon, students may stop their education.
The village people desperately want to get their children back into school but at the moment buildings are just not safe to enter."
He had already been to Nepal following the April earthquakes.
