A Wellington teacher who allegedly had sex with a student at a motel has denied the encounter took place but could not account for his knowledge of her room.
The woman, whose name is suppressed, has been charged with indecent assault, sexual violation and unlawful sexual connection when the boy was between 10 and 13 years old.
She took the stand in the High Court at Wellington today to deny the charges.
The teacher admitted to visiting the motel but she didn't know how the boy knew the details of her room.
She also denied exchanging text messages with him, including on the day of the boy's father's funeral, and hiding him in the back of a van under a tarpaulin from her mother.
"It would be inhumane to put a child under a tarpaulin like that," she told the court.
Although she knew the boy had "an infatuation" with her, and had told other children they had sexual encounters, she didn't raise the issue out of fear of his mental well-being.
On Tuesday, the boy told the court he wanted to be in the relationship with his teacher and he wanted to have children with her.
He said he considered her his girlfriend and they exchanged explicit messages including photos of their body parts.
Their relationship allegedly began in 2011 as just kissing but later progressed to sexual touching then oral sex and on a single occasion, sexual intercourse.
He was 12 at the time of the alleged sexual intercourse.
Police were called when another teacher at his school confiscated the boy's phone when she believed she saw inappropriate text messages on it.
The trial continues.
