Young fighters raised awareness of suicide at the Warriors in Paradise 2 event in Waitangi on 7 November.
Organiser Nik Jessop said his family experienced suicide and that it leaves a wake of grief behind.
“It still hurts. It really cuts deep.
“Everyone lashes out at each other. They get angry then start looking internally at what they could have done.
“You’re left with all these issues unanswered and there’s nothing you can do about it because it’s finite.”
