The four runners-up were Lorisha Lila Kahn (Clendon Park School), Caitlin Mackay (Fairhaven School), Phoebe Wylie (Opaki School) and Amanda MacArthur (St Patrick's School).
Colour Your Classroom judge Mark Norling, from Sharpie, was impressed by the creativity and thought that had gone into all the entries he read.
"The ideas expressed by these students went far beyond what I'd anticipated.
"It bodes well for our future that we're seeing such innovative thinking from some of the country's youngest students."
Colour Your Classroom launched in 2014, and is supported by stationery and office supplier OfficeMax, who this year presented each of the five winning students with a Sharpie and Paper Mate special edition colouring kit, valued at $44.99.
