Photos of young children holding assault rifles as part of a school visit by the Army have caused Education Minister Nikki Kaye to order new guidelines be drawn up on guns in schools.
Pictures of smiling children holding the unloaded weapons appeared in the Manawatu Standard last month.
The Army has started a new programme teaching children about weaponry and leadership, and started it at Whakarongo School near Palmerston North.
Students aged 9 to 13 were able to assemble and fire an assault rifle.
Kane O'Hara, 11, told the newspaper that he had never held a gun before and "it felt amazing and cool" while deputy principal Lisa Cuff said she did not think the visit would be controversial.
