A Dunedin scientist convicted for assisting the suicide of his mother, who was dying from cancer, is flying home to South Africa on Sunday.
But before he goes he will speak out for euthanasia.
Sean Davison has been freed from five months' house arrest, and is taking part in a debate on euthanasia tonight at the University Of Otago.
Davison's mother was terminally ill with cancer when she died in 2006.
