"The message that we share isn't just for the forestry industry," Mr Edmonds said.
"It's become industry-wide. We're representing ourselves as parents and then representing our families and friends who have held us up. We're also representing industry leaders of this country, their workers and because of my role with the ACC steering committee I'm representing every man and their families in New Zealand and every soldier who has been lost in the industry before and after our son.
"It's not just about our son any more. It's about standing in the gap for the weak, the strong and the people who are looking for a little bit of courage - people who want to be inspired."
John Deere, Waratah and Bell Equipment have sponsored the trip.
After months of the talks being delivered by Mr Edmonds, Mrs Edmonds also now takes to the floor to share her experience. "Emotionally it's quite draining. We're reliving it each time we share the presentation. A lot of people have asked me as a mum, how do I do it?
'When you have been to the abyss of pain you don't want any other mum to experience that. It's something we will live with for the rest of our lives.
"If I can contribute to young men making the right decision and that helps save one life, then I've achieved something."
Major Nelson, the foreman in charge on the day of Mr Ruri-Epapara's death, admitted a charge under the Health and Safety in Employment Act 1992 that he, as an employee, failed to take all practicable steps to prevent an action of his at work, namely felling a tree, from causing harm to Mr Ruri-Epapara. He was fined $35,000 and ordered to pay reparation of $15,000.
He has lodged an appeal against his sentence, which is due to be heard next year.
