Staff at a Wairoa school used to be so worried for the kids they were teaching that they would bring food from their homes for them.
Research for KidsCan by Colmar Brunton on food insecurity in schools has highlighted the challenges children living in poverty are facing every day.
Researchers found a lack of food is "just one aspect of the myriad of functional challenges" that some children face.
It also found that "teachers are getting hit from all angles" with the job consuming their time, effort and money as they take care of child welfare before they can teach.
Te Kura Kaupapa Maori o Ngati Kahungunu o Te Wairoa office administrator Phillecity Ngarangione said before the school lunch programme began last year and they started receiving food from KidsCan, the staff took it upon themselves to keep classrooms stocked with food for students in need.
