New Zealand's Mental Health Foundation says it has received an unprecedented number of calls from distressed members of the public following Robin Williams' death.
The actor and stand-up comic was found dead from an apparent suicide in his California home yesterday.
The story of his sudden death and the many tributes to him have made front pages and led news bulletins around the world.
"There can be a connection between a celebrity suicide and an increased rate of suicide," Mental Health Foundation chief executive Judi Clements said today.
She had never seen as many calls to the Foundation. Many of the callers were people who had been affected by suicide, and the reporting of Williams' death had brought back great grief or loss for them, she said.
The organisation behind the Oscars - the Academy of Motion Picture Arts and Sciences - sent out a tweet following Williams' death saying "Genie, you're free", which by this afternoon had been shared more than 300,000 times and potentially viewed by thousands more.
There have been concerns raised by mental health professionals worldwide over the tweet's suggestion that suicide was a form of liberation.
Nobody should ever encourage or even hint at the notion that suicide was an option, Ms Clements said.
People must realise that death was a tragic loss in any situation, whether the person was high or low profile. Family, friends and the wider community could be severely affected by a suicide, she said.
Ms Clements encouraged anyone feeling down to talk about their feelings. Encouraging others was great therapy for those who had been depressed and for those who currently were, she said.
"There is always hope, always recovery for people who've been in desperate places and have found their way through it."
"There is help out there to turn to. Friends; people who care."
