Proceeds raised through last year's challenge went to the Mental Health Foundation of New Zealand and this year Lifeline has been brought into the fold after calls to the national helpline trebled in the last year.
Hawke's Bay is one of many regions that has experienced rapid growth in call rates with numbers increasing by about a third in the space of one year; jumping from 5115 in 2016 to 6807 in 2017.
Matty, who is one of 2500 New Zealanders across 46 Snap Fitness gyms fundraising for Lifeline, said he hoped to do his part to break the silence on suicide.
"I'd really encourage people to challenge themselves and get outside their comfort zones when they are in dark places, and that includes finding someone to talk to.
"Really get outside of your comfort zone and challenge yourself to make new habits. You only find growth outside of your comfort zone so get out there."
Now into week two of his second 8 Week Challenge, for which entries are now closed, the 30-year-old early childhood educator said exercise helped him establish healthy routines.
"The sense of achievement from that was incredible. The challenge gave me a goal, it gave me pressure and it gave me focus.
"Rather than going into the gym kind of blase without a timeline to achieve everything the challenge gave me that and good habits as a result of that. Those were major benefits."
He said the moment Jono Pryor, co-host in the TV show Jono and Ben, paid a tearful tribute to a mate he lost to suicide during a live show in March last year highlighted the importance of speaking out about mental illness.
"It's the silent killer and one thing that resonated last year was Jono and Ben; they hit it home. We've got the worst statistics in the developed world.
"It's a hard thing to talk about and I guess I'm an example of that in trying to break the silence. I try to talk about my mental state all the time so people know it's okay to not feel happy some days and how to deal with that."
Lifeline and Snap Fitness aim to generate $250,000 in donations. Those wishing to show their support can donate by visiting www.8weekchallenge.co.nz.
