Martin said New Zealand Samaritans had had some discussions with the Department of Corrections about prison listening, but it was still in the early stages.
Since returning to Wellington, Martin has given a presentation to the Samaritans board of trustees and written a detailed report about the conference.
She will also present a paper to the New Zealand Samaritans' annual conference next month.
She enjoyed the trip and the conference.
"It was just absolutely wonderful to have this experience."
The New Zealand Samaritans is a confidential listening and support telephone service operating 24 hours a day for people who may be feeling depressed, lonely or even contemplating suicide.
