But Codyre said people hadn’t become “meaner”, and the good could come from the “collectivism” of the online community, where complete strangers offered support, empathy and hope to people they have never meet.

“What we have to encourage is people being collectively responsible online; we need to help ourselves as communities of people to learn the rules of living in this new world, just as we had rules around how we lived in the old pre-technology world.

“We should think about how we maintain a set of understandings around what is and isn’t good behaviour in this new world.”

Codyre said multiple factors could be driving our high suicide rate in New Zealand, which had seen a big shift in divide between rich and poor.

“One of the biggest drivers of poor mental health and suicide risk are things like poverty, unemployment, crowded housing and despair.

“A lot of young Pacific people talk about the fact that they live in two worlds: they have their social circle; they also have the world of family obligation and expectation.

“These worlds can easily conflict; it becomes incredibly stressful and proves difficult to develop a strong sense of identity.

“We still have this culture in New Zealand that we have to be tough; that to admit we are struggling is a sign of weakness.

“The newly released suicide figures are deeply saddening; far too many people unfortunately still don’t ask for help when they desperately need it, and it literally kills them.

“The more people know there is help out there, via text or phone, the more we can change this.”

Over the past century, the rate of stress, depression and anxiety problems have grown decade by decade.

“Communicable diseases are still the leading cause of deaths in the developing world, yet in the developed world sometime in the next few years depression is going to become the leading cause of disability related to health issues – overtaking cardiovascular disease, which is currently the leading cause.”

While Pacific-born people had the lowest depression risk of any group, New Zealand-born Pacific people had the highest depression risk.

“Partly that’s about cultural change and the breakdown of traditional family structures; partly it’s about things like dietary changes.

“Diet in the Pacific and diet in New Zealand for those populations is clearly different.”

Evidence showed a clear connection between diet and depression.

“A poor quality of diet doubles the risk of depression; there is now evidence that shows a healthy diet – partly based on what genetically is a healthy diet for someone – has a treatment effect in cohorts of people that are depressed.”
