She took him to the Mt Vernon car park, and when the boy asked about his classes, she told him not to worry and said she would fix his attendance record.

The woman became emotional, and got into the back seat with him. She flirted with him, sat on his lap and kissed him, before giving him oral sex, the summary said.

She asked the boy if he'd had sex before, and he avoided the question, saying he had sport, she took him back into town and dropped him off near the school.

She told him not to tell anyone, the summary said.

During another lunchtime, she drove the boy to the A&P Park car park and they had sex in the back seat.

They met again for sexual activities in the car on several occasions, often on a Friday after school while the woman waited to pick up her child.

He believed they were in a relationship. She would say she loved him, and tell him that he was amazing, the summary said.

The woman would often say she wanted to kill herself, which made the boy feel like he could not break up with her, the summary said.

The relationship lasted a year.

She would take explicit photographs of herself while she was in the bath or in bed, and send them to the boy through SnapChat, or video call the boy through FaceTime.

Near the end of last year, the boy invited another boy to a group chat online with the woman.

The three of them spoke about sexual matters and the next day, she picked the boys up and drove them to the Horton Park car park, where they all got into the back seat and had oral sex.

Then they spoke about "work and school stuff", the summary said, and she dropped them off at the gym.

On another occasion, the second boy visited the woman in her classroom, and they started "play fighting", and then kissing each other.

She said they needed to go elsewhere, and told him to meet her down the street. 

She picked him up in her car and drove him to the A&P Park car park, where they had oral sex in the back seat.

They continued to meet for oral sex on several occasions, the summary said.

During the Christmas holidays last year, she picked the first boy up and drove to Richmond View School car park, where they had sex in the back seat.

He eventually told the woman he wanted to end their relationship, but the woman kept messaging him, telling him that she loved him.

She also sent an indecent video of herself and nude photographs.

When spoken to by police, the woman declined to comment.

The woman, a former teacher in Marlborough, admitted seven charges of sexual relations with minors and two charges of sending sexual material to minors at the Blenheim District Court on Tuesday.

The woman showed little emotion in the dock, frowning slightly as the summary was read aloud by police.

Her lawyer Jonathan Eaton, QC, asked for name suppression to be continued, to protect the identity of the complainants. Police did not oppose the application.

Judge David Ruth referred the case to restorative justice, where the woman could meet the boys and try to make amends, if the boys were willing.

He ordered a pre-sentencing report "so all sentencing options would be open", and continued name suppression, but said it would have to be fully argued at sentencing.

The woman was convicted and issued a first strike warning, which meant harsher penalties for repeat offenders of serious violent and sexual crimes.

She was remanded on bail to sentencing on December 17.

If sentenced to jail, she would be added to the Child Sex Offender register under the Child Protection Act.

Otherwise it would be up to the sentencing judge whether her name was added to the list.
