Mr Ballantyne (21) is giving a presentation in the auditorium at Waitaki Boys' High School on Monday night about the Global Poverty Project.
The former Waitaki Boys' pupil has spent the past three years studying for a bachelor of arts degree, majoring in politics and theology, at the University of Otago.
Last year, he managed the organising committee for the launch of the Global Poverty Project in Dunedin, where former Young Australian of the Year Hugh Evans showed about 1200 people how they could help by making simple changes to their lives.
Mr Ballantyne's free presentation was about raising awareness of the issue and giving people practical tools to help eradicate extreme poverty.
It was "definitely do-able", he said yesterday.
He promised the presentation, which is being organised by the Oamaru branch of Altrusa International, would be inspiring and informative.
He had been impressed with the amount of money Oamaru had raised through Project HHH - Hearts and Hands for Haiti - to aid earthquake-stricken Haiti.
