The majority support Mrs Bennett, but some have voiced concern about the nature of her death being made public - which they believe "glamourises suicide" and could spark copycat deaths.
Mrs Bennett wanted her letter to start a global conversation about the right to die. Her grieving husband yesterday thanked those participating in that conversation, but did not want to respond to individual opinions.
"I'm very glad that Gillian's example and message are being spread in New Zealand," he said.
"I have been public about my support for Gillian and my belief that it is good to have the conversation reopened."
Assisted suicide is illegal in New Zealand. Under Section 179 of the Crimes Act 1961, anyone convicted of inciting, counselling or procuring another person to commit suicide or who physically helps them in any way to take their own life faces a maximum of 14 years in prison.
