Kiwi Robert Martin MNZM became the first person with an intellectual disability to chair a United Nations session on Wednesday.

Mr Martin, currently serving a three-year term as an independent expert on the UN Committee on the Rights of Persons with Disabilities, says the occasion in Geneva was empowering - but he was initially uncertain.

"I was a bit apprehensive when the secretary of the committee asked me to chair. But I had great assistance from the secretariat and my own assistant, and they assisted me to know what was expected of me. And I've actually been studying what the other chairs do and say, and learning from their great example."

Mr Martin continued: "The other members of the committee were all supportive for me to have a go. To me, I think this is what the Convention [on the Rights of Persons with Disabilities] is about. People with disabilities, including people with intellectual disability, having a say and showing the world that yes, we can do this."

Mr Martin chaired three sessions over the course of the week, as the Committee on the Rights of Persons with Disabilities concluded a four-week block of sessions in Geneva.
