A former teacher has admitted seven charges of sexual connection with two 15 year-olds in Marlborough.
The woman also pleaded guilty to exposing a minor to sexual material, when she appeared in the Blenheim District Court on Tuesday.
A police summary of facts said she had sex with one of the boys a number of times, before later suggesting another teen under the age of 16 join them.
She then had sex with the two boys in the back of her vehicle.
The summary of facts says the offending began in 2017, when she started exchanging messages with a boy below the age of 16, reports Stuff.
She also sent "explicit videos" to her victims.
She has been remanded on bail for sentencing in December, and has interim name suppression.
The woman was arrested and charged in July amid the claims of sexual allegations.
