A boy in the case involving a former Marlborough teacher convicted on charges of sexual misconduct with students, believed he was in a relationship with the woman.
The woman, whose name is suppressed, admitted in the Blenheim District Court today to seven charges of sexual relations with minors and two charges of sending sexual material to minors.
It began with messages sent by text, that escalated into a relationship described in court as one of trust.
The pair met on several occasions over the next year, and the boy believed they were in a relationship.
The woman began sharing explicit photos of herself via private social media platforms, and another student was invited to join in.
A series of illicit meetings then began with two students.
The woman was today convicted and remanded on bail for sentence in December.
