Act candidates were invited however could not attend due to a clash in meetings
The debate will be hosted by Huhana Lyndon, general manager of Te Matarau Education Trust, and each candidate will be asked a question and given one minute to answer.
Peter Lucas, from Te Hiku Media, said the debate focused on inviting those from the major parties that are likely to be part of the next government.
"We had to think about how many people we had on the stage and it was really a practicality that we invited those candidates, and that's not a reflection on the other candidates standing, but we had to make the decision for practical reasons." Mr Lucas said.
Lyndon said the debate is the chance for the public to see candidates from the Tai Tokerau, Whangarei and Northland electorates go head-to-head on matters of importance for our region.
The debate will be screened live online at tehiku.nz, and on radio stations Tautoko FM, Ngati Hine FM and Te Hiku FM, with support from NZ On Air.
