He was chosen because of his trusted voice and television presenter Greg Boyed would turn out to be one of their most popular celebrities used in a mental health campaign.
Boyed was one of several well-known Kiwis who front Step Forward, an initiative to help bring an end to mental illness discrimination.
Mental Health Foundation spokeswoman Sophia Graham said a tweet from Boyed, who died in non-suspicious circumstances while holidaying in Switzerland on Monday, was hugely popular.
"His tweet about our Step Forward campaign was our most popular tweet. It seemed to mean a lot to people that he would be open and encourage people to step in and help friends and whanau when they were going through a difficult time.
"His presence in particular seemed to bring enormous comfort and support to people that he would speak out about such a difficult subject."
