SANE advertising

This effective 'road' sign comes from a campaign being run by SANE Australia. There's a brief video ad on the site from a campaign focusing on mental health. One of the main messages SANE is promoting is that often close family members see the signs even before the person who's having mental health problems. This leads to them needing to encourage the person to get help. The campaign is similar to the one shown in NZ in regard to depression.
It's an importantpoint to note that:

The 2005-2006 data shows that the rate of suicide is higher for Mâori (17.9 per 100,000) than non-Mâori (12.0 per 100,000). This disparity has increased over the past nine years.
While fewer Mâori people died by suicide in 2005 than in 2004, the three year moving average rates - a more robust measure of what’s happening over time – show the Mâori suicide rate has increased by 5.2 percent from 2002-2004 to 2003-2005.

Addressing the needs of Mâori is particularly important because Mâori also have poorer outcomes in other areas relating to suicide. For example, depression is a major risk factor for suicide. Te Rau Hinengaro: The New Zealand Mental Health Survey shows that Mâori report higher rates of depression than all other ethnic groups, and, with the exception of Pacific peoples, are less likely to access services for a mental health problem.
