The fire service has told volunteers in next year's charity calendar not to reveal full names after a prisoner asked a former firefighter model for a date.
The woman, who would not be named, was contacted by the prisoner in Auckland Prison at Paremoremo.
Auckland Airport firefighter and calendar production manager Tony Scott said the incident led him to warn firefighter models not to give their full names during media interviews about the calendar.
The Auckland volunteer firefighter received the prisoner's letter after she was interviewed by a community newspaper about her appearance in this year's calendar, which raised money for child cancer.
"He said he'd love to visit her when he got out and he wanted to date her."
