A woman who made a false rape complaint has agreed to front up to the police investigators whose time she wasted, in an attempt to make amends.

The 27-year-old, who cannot be named, told a detective she was pulled into a car and raped while walking home from a bar in Blenheim in February.

But after a medical examination, extensive investigations and a DVD evidence statement, police found the woman was lying.

After she admitted a charge of making a false complaint to police, a judge referred the woman to restorative justice, where she will meet with the victims of her offending.

Police said they had wasted "significant hours" on the investigation, and other important cases had been set aside so they could investigate the alleged rape.

A police summary of facts said after the woman contacted police, she had a medical examination, as was procedure.

She told the doctor she had not had sex for about 10 days before the alleged attack, a police summary of facts said.

The next day she went to the Blenheim police station and after promising to tell the truth, gave an evidential statement recorded on DVD.

The woman said she left the bar about midnight, and was walking home along Weld St when a black Holden Commodore pulled up beside her.

She claimed a man opened the back door and grabbed her bag, pulling her into the back seat, and then raped her.

Another man drove the Commodore further on Weld St, and eventually pulled over near Hospital Rd, where the man in the back pushed her onto the footpath, the woman said. She walked home and went to bed, she said.

After the woman's complaint, six investigators were put on the case, who made extensive inquiries, canvassing the Weld St area, the summary said.

Police later found on the night the woman claimed to have been raped, she had actually had consensual sex with a man she knew.

The woman must have known the medical examination would lead investigators to that man, police said.

She admitted a charge of making a false rape complaint at the Blenheim District Court on Monday.

The woman's lawyer Laurie Murdoch sought name suppression for her client, arguing publication could affect her children and her employment.

She also asked for no conviction to be entered, as they were considering applying for a discharge without conviction.

Judge David Ruth granted interim name suppression, but said final name suppression would have to be "fully argued" at sentencing.

He also referred the woman to restorative justice, where she would try to make amends to her victims.

Police officers involved in the rape investigation were expected to provide victim impact statements.

Judge Ruth remanded the woman on bail to October 30 for sentencing.
