The One Young World Summit is a call to action for tomorrow's leaders.
For the past three years, the non-profit organisation has brought together the best and brightest 18 to 30-year-olds to discuss critical global issues.
15 youth leaders from around the world have been selected from 13,000 delegates to speak at this year's event, which kicks off in Johannesburg tomorrow.
For the first time, Māori will be represented by Matthew Kenny of Tainui/Waikato.
