LATEST: A man being hunted for an alleged rape in Sockburn was wearing a high-visibility fluorescent vest.
The man was not known to the victim, a woman in her 20s.
Police are still looking for the suspect, a Polynesian in his 40s with two front teeth missing, in various parts of Christchurch.
The "intruder rape" happened at a Middlepark Rd address just before 10.50am today.
The victim received medical treatment at the scene, and is now being cared for by family members.
Up to 30 police have been working on the investigation this afternoon.
A scene examination is under way at the property and is expected to continue tomorrow.
Detective Senior Sergeant Darryl Sweeney said investigators were still working to confirm exactly what happened.
"Our priority at the moment is the ongoing care of the victim and her family".
He said the man might be wearing a hi-vis vest.
"We are appealing for anyone who may have seen a person answering this description, or any other unusual activity in the Middlepark Rd area between 10am and 11am, to contact police urgently," Sweeney said.
"We would also like to hear from anyone in the area who has noticed any suspicious activity or vehicles in the vicinity over recent days and weeks, including unfamiliar people knocking on doors or visiting properties.
"The attacker was not known to the victim."
A nearby resident told The Press that police knocked on his door shortly after the incident.
Police told him the man had shoulder-length hair and was wearing a fluorescent vest.
The resident said he often walked his children in the area and had never seen anyone fitting the description.
"It's very scary," he said.
"Hopefully they get him very quick."
Another neighbour, who did not want to be named, said she had just left her house for work at the time of the incident.
The woman said she did not see or hear anything suspicious, but it was a busy street and she would not have thought twice if she saw someone walking by.
However, she had always felt "paranoid" about something like this happening as she was often at home by herself, she said.
St Thomas of Canterbury College pupils Sidney Jenkins and Nick Bradley said police came to their school about 11am and teachers told everyone to stay in their classrooms until further notice.
The nearby school was let out of lockdown about an hour later and had returned to normal, they said.
Nick said he had lived in the area for about five years and it had always been a good neighbourhood.
"Nothing bad ever happens," the year 13 pupil said.
