The rationale behind Ag Mental Health Week was simple, Hynes said.
"Let's get talking about mental health and normalise the conversation."
The week-long online and social media campaign aimed to highlight the importance of mental health for those who work in agriculture.
Any Kiwi farmers who wanted to take part could get involved through their social media platforms, by posting a message about how they take care of themselves and adding the hashtag #AgMentalHealthWeek, Hynes said.
A couple of well-known New Zealand dairy farmers had helped the initiative kick off already, Hynes said.
Waikato's Sam Owen had taken part in a panel discussion, and Bruce Eade from West Otago had launched the initiate in New Zealand, Hynes said.
"Sam's is a really top bloke. He's gone through the mill and he's been at rock bottom, but all credit to him, he's really got himself into a good place."
"Bruce Eade is actually the first video that we launched late on Friday night to welcome New Zealand into World Mental Health Day."
Hynes hoped the initiative would get people sharing their experiences and reduce the stigma around mental health issues.
"If we can normalise the conversation, it gives someone that's at a crisis point the confidence to feel that it's OK to talk about how dark a place they are in, and not be afraid of reaching out and asking for help."
"If we stand together as a global farming community, we can do a lot more to break down the stigma."
Also in today's interview: Hynes talked about how Covid-19 and an impending winter was affecting farmers in the UK and Ireland.
