"It was a big thing and it was like why is this happening and there was no support for families after.
"They had AA for alcoholics, support for gamblers, grief support groups for stillborns and SUDI and other things like that."
HopeWalks, started by Auckland pastor Joseph Fa'afiu in 2015 as a way of breaking the stigma around suicide, are held around New Zealand and Australia.
Suicide statistics from June 2015 to June 2016 showed there were 21 suicides in Northland .
The Whangarei walk will be held on September 10, World Suicide Prevention Day, from 7pm to 8pm.
People are encouraged to wear yellow and black and bring torches or LED candles to shine at 8pm.
"We need to stop the stigma and the silence so that people will reach out. To show there's no shame to talk," Ms Ritchie-Warren said. "So many people have been affected by it and to know suicide rates are higher than the road toll is eye-opening."
The walk will start at the Canopy Bridge but the route is yet to be decided. So far 200 people have indicated they will be attending the walk.
