The KidsCan charity says an "epidemic" of poverty-related illnesses makes earthquake-damaged eastern suburbs of Christchurch its next priority for school-based health services.
Chief executive Julie Chapman said schools in the area that receive KidsCan food have reported increases in respiratory and skin infections because many families were forced to share housing after the February 2011 earthquake.
"We want to get in there now because of this epidemic of poverty-related diseases because of the poor housing conditions."
Mike Allen, principal of Aranui School in one of the worst-hit areas, says many parents can't afford treatment for their children.
"It's not the doctors' fees - children are free," he said. "It's the parents getting the children to the doctor and then paying for the treatment."
