Mr Dunne has said the suicide rate was unacceptably high, particularly among Maori, and today he said the initiatives in the national suicide prevention plan would be developed in a way that was responsive to Maori.
The plan already encompassed many of the ideas and challenges which had been raised at today's forum, he said.
Mr Dunne said a call for more youth participation, from mental health advocate Mike King, had to be a guiding principle moving forward.
"Our young people have the best opportunity and value for the future, and that is where our investment has to go because the biggest tragedy of all is the wanton loss of young life," Mr Dunne said.
Mr King told the forum that suicide prevention started with education.
"And our kids need to be involved in the debate - they have been excluded - and I am hoping after today that a greater role will be played in our education system, to get our children involved in this debate.
"Our appalling suicide statistics do not change until our children lead the way."
Among the new initiatives in the national suicide plan are support for small communities which lose major industries, more support for families of suicide victims, a social media trial on suicide prevention and tackling cyber-bullying, and funding to develop better knowledge of contributing factors and patterns of suicidal behaviour in New Zealand.
