The extensive air, ground and water search for the western Sydney girl has ended after seven days of police combing areas around her family's Mt Druitt unit.
Police announced on Sunday that the physical search has concluded, but Strike Force Jarocin will continue to investigate Kiesha's disappearance.
Kiesha was last seen about 9.30pm (AEST) on July 31, when her mother, Kristi Abrahams, put her to bed.
She was reported missing the next morning after her mother discovered her bed empty and the front door ajar, although it showed no sign of forced entry.
It was previously thought she had not been seen by anyone outside her immediate family since July 7.
But police on Saturday said they were investigating reports from a female neighbour who said she saw Kiesha with a relative a week before she went missing.
Detectives on Friday refused to confirm if they had any suspects following claims by the child's stepfather, Robert Smith, on Friday that police had accused him of killing Kiesha, telling him to "lead us to her body".
Mr Smith, Kiesha's mother and the girl's biological father, Christopher Weippeart, were all interviewed by police on Wednesday.
Investigators are appealing for anyone who may have seen Kiesha on or after those days to contact Crime Stoppers on 1800 333 000.
