Awarded for the first time in 2013, the scholarships make a contribution towards sports gear, coaching, travel or other resources to help athletes work towards their goals.
Mitchell said he intended to put his award towards a new pair of shoes and travel.
New Zealand Children's Athletic Association president Brian Cockeram said the awards were not only for great performances but also excellent attitudes.
The level of dedication and talent contestants exhibited last week impressed Colgate NZ general manager John Garside.
The 2016 Colgate Games ambassador and New Zealand champion 1500m runner, Julian Matthews, said it was grounding to see children competing at such an intense level.
Rio Olympics hopeful Matthews said it brought back fond memories of his own time at the games:"It's important to remember that natural talent will only take you so far and that it's your attitude that will take you to the top."
