"This time when I rang the police they came and took him away in a straightjacket in the police car with an armed officer."
Police asked the MidCentral mental health team to assess the man.
"At 1am he rang me. He had been assessed, there was nothing wrong, they said, and he was coming home.
"But I had to meet the police halfway between Dannevirke and Palmerston North.
"I know when somebody isn't quite right, they're only going to tell you what you want to hear. And no one gets right in four hours.
"You have got to look at this, or there are going to be more and more under the ground.
"I'm lucky my family member is still alive."
In an earlier incident, the Armed Offenders Squad had been called to the farm.
As he held back tears, Mr Rosacker said he appreciated there were financial pressures on the mental-health system, but begged the district health board members to look at the services they delivered.
"Why assess them and let them go?"
Kathryn Cook, chief executive of MidCentral Health, said mental health was a real priority, and that there had to be fundamental changes.
Health board chairwoman Dot McKinnon agreed.
"Mental health issues are going to be greater [for us] than those associated with our ageing population," she said.
Norsewood's Kathryn Mulinder sympathised with Mr Rosacker.
"People are seen, assessed and sent home from MidCentral and in a few days they're dead," she said.
"There's no follow-up and these aren't isolated incidents."
Tararua District Mayor Tracey Collis hugged Mr Rosacker and said he was "absolutely courageous in telling his story".
"It's been extremely powerful."
Mr Rosacker told the Dannevirke News, "it's the pain people [who commit suicide] leave behind. I've dismissed three staff for being on meth and then one took his own life three weeks later and I got the blame".
"I'm very concerned about those dairy farmers milking lots of cows, up at 2.30am and still going at 7pm. Some take stuff . . . "
Now, at a big cost to himself, Mr Rosacker carries out regular hair-follicle drug testing of his staff.
His family member is now receiving ongoing counselling.
