Rishworth said the national speech competition, initiated by the New Zealand Baha'i community in support of Race Relations Day, was in its 19th year.
She said the winner of the Northland regional heat - held at the Whangārei Baha'i Centre on Thursday, April 11 - would advance to the semifinals in Auckland.
During the weekend of the finals there is also a hui on race relations where workshops are held around the topic.
"It really can be a life-changing experience and a really positive thing for the students."
Rishworth said nine Northland students from six different schools - Huanui College, Whangārei Boys' High School, Whangārei Girls' High School, Christian Renewal School, Kerikeri High School, and Bay of Islands College - had entered and registrations were still open.
She said the competition targeted youth as champions in promoting racial harmony and tolerance towards all people regardless of their creed or ethnicity, and challenged them to think of crucial issues facing not just young people, but society in general.
She expected the Christchurch mosque attacks to be a part of students' speeches this year.
"I think that this year I would imagine that what's happened here in New Zealand would feature quite prominently in the speeches and the students perceptions, their feelings, their experiences around that may well come to the fore."
The judging panel for the Northland heat includes a representative of the New Zealand Police, Paula Wilson, of Te Puna o Te Ao Marama Trust, and Jessie Manney, of Multicultural Whangārei.
Members of the public are welcome to attend the regional competition heats. Admission is free.
