The Cowans soon realised that already-established victim-centric groups were about creating solutions rather than remembering the actual victims. So that's what they set about doing.
"There's no day like that on our national calendar at the moment ... we want to roll this across New Zealand and we're hoping it will become a national event," Mr Cowan said.
"We're surprised it hasn't happened before."
"We draw parallels with Anzac Day. Not everyone's sons, daughters or grandfathers have been off to war, but everyone still gathers on the 25th of April to remember what they gave for this country."
The first White Heart Day was held in Napier only, but this year events will also happen in Auckland and Wellington.
Guest speakers at the hour-long "reflection" include Tracey Marceau, whose 18-year-old daughter Christie was murdered in their North Shore home last November, Zack Makoare, whose son Kelly committed suicide, and Tyler McKelvey whose cousin Steven Stone was murdered.
The events are open to anyone who has lost a loved one in tragic circumstances, or who wants to remember victims in general.
