It had the support of more than 200 bereaved families and asked politicians to "have the courage to put aside politics and do what is right for every Kiwi".
Today a number of those families are telling politicians exactly how they would like them to do that.
They want a national suicide reduction target, an inquiry into New Zealand's mental health crisis, the restoration of $2.3b in health funding, an increase in primary health and GP funding, safe mental health staffing and healthy home regulations.
Initially, neither National nor Act responded to the request to attend today's discussion.
Two bereaved family members said they would instead wear chicken suits with a blue and yellow tie to sit in their place.
But representatives for both National and Act turned up, joining representatives from the Green Party, Labour, NZ First and The Opportunities Party.
The Internet Party, Maori Party and United Future have sent messages of support for today's event.
The Internet Party leader also offered to speak by Skype from Russia.
