A transgender Oamaru woman sentenced on Wednesday to nine months' imprisonment in a men's jail could apply to be moved to a women's prison.
A new system for transgender prisoners was introduced on February 10 in which prisoners who have changed the gender on their birth certificate are automatically put into a prison based on that gender.
Department of Corrections southern regional commissioner Ian Bourke said transgender prisoners whose sex on their birth certificate had not been changed could apply to be moved, but applications would be considered case by case.
"If they are unsuccessful with this application, transgender prisoners will be accommodated according to the sex recorded on their birth certificate," Mr Bourke said.
"No prisoner will be permitted to make an application for placement if they have sexually offended against a person of the same gender as the prisoners they wish to be co-located with."
