The court heard how the woman was a wellness co-ordinator at the school she worked at until May this year. She would talk to the victims about mental health problems and tell the victims not to worry about school attendance because she could "help".
Before a packed public gallery, hands clasped, she stared straight ahead as she listened to the charges.
She admitted seven charges of unlawful sexual connection with minors, and one of exposing a minor to indecent material over a year-long period.
The judge issued a first strike warning for the nature of offences and the woman was ordered to report to Blenheim community probation service by 4pm.
She was remanded on bail until sentencing on December 17.
It is understood the indecent material was photographs and videos.
The woman appeared in the Blenheim District Court in August and had been remanded on bail with interim name suppression.
Her bail conditions included a total ban on any contact with a person under 16 - apart from family members.
However, the woman was later spotted at several youth sports games in the Marlborough district, leading to an outcry from concerned locals.
She was there to watch a young relative, but her presence sparked outrage.
