The judge imposed suppression orders that include the defendant's name, the victim's identity, and police summary of facts.
She said the interim suppression orders are necessary to protect, not only the victim, but fair trial rights, but stressed that they will likely be reviewed at the next court appearance.
Detective Inspector Darryl Sweeney said yesterday that police moved swiftly to track down the man they believe is behind the crimes.
"My deepest sympathies go out to the family of this young woman and police will be ensuring that they are supported following their tragic loss," Sweeney said.
"Our police team of highly-experienced and dedicated investigators have worked tirelessly to ensure justice for the victim and her family, and will continue to do so."
Police say they will not release the woman's identity until all family members have been informed of her death.
An autopsy is expected to be carried out today.
A team of experts continue to piece together information, with detectives and forensic specialists examining two scenes in Christchurch – one at Exeter St and one at Breezes Rd.
"Residents in those areas can expect to see a continued police presence over the next few days," Sweeney said.
Two motor vehicles have also been seized for examination.
No one else is being sought in relation to the woman's death, Sweeney said.
However, he said police would like to hear from anyone who was in the wider Exeter St area overnight Friday to Saturday that "may have heard or seen anything, or anyone, suspicious".
People are asked to contact Canterbury Police on 03 363 7400 if they may have information or anonymously via Crimestoppers on 0800 555 111.
