The competition was judged by current national poet laureate, Vince O'Sullivan.
Mr O'Sullivan said Emily's poem was written in a voice for a contemporary person.
"It was saying even if we forget where the battle was, the significance of the history hasn't diminished by our ignorance of that. Individually, the lines ran true and convincingly for me."
Organiser Buddy Mikaere said there were some great entries but he thought it was fantastic Emily won as "in a way, she is the target audience".
"To have someone write a poem that shows a mature grasp of the event is just fabulous."
The competition final was held at Elizabeth Street Cafe and Larder last night and the $1000 prize was sponsored by Eves Bayleys Realty.
