"Mummy did bleed everywhere ... and mummy scream," she told police.
A court earlier heard how Gottermeyer had been suffering from a significant depressive illness.
Justice John Fogarty jailed Gottermeyer for life last November, but adjourned the case for a psychiatrist's report under section 104 of the Criminal Procedures (Mentally Impaired Persons) Act to be prepared, to establish his mental state of mind at the time of the killing.
The judge asked for the report to include notes on why Gottermeyer was still on medication, why he was an outpatient at Hillmorton when the murder occurred, and any other clinical observations which would assist the court in judging the extent of "his history of depression and associated episodes".
The Canterbury District Health Board (CDHB), which has responsibility for Hillmorton, carried out an investigation into the tragic case.
"Our internal reviews have not found any faults in the care provided to this patient nor have there been any recommendations to the Health Quality and Safety Commission," said Dr Sue Nightingale, the CDHB specialist mental health services chief of psychiatry.
The woman and her daughter have been granted final name suppression.
About 50 family members and friends of the victim filled the court last year to see Gottermeyer sentenced and tell him how the crime had affected the family.
The woman's distraught father asked the killer why he had taken his "little princess".
"Life will never be the same," he said. "I feel angry and betrayed."
Other family members say the young girl, who was three at the time of the attack, suffers night terrors and relives the ordeal.
The woman's brother told Gottermeyer the impact had been "sad and sickening".
The court heard how Gottermeyer left home at 7am on July 11 last year with a large kitchen knife and drove to the woman's house.
He was let inside where a heated argument developed in the kitchen.
Gottermeyer knocked her to the ground, and stabbed her repeatedly in the head, hands, chest, and back, before slashing her throat.
When he was arrested, he said the girl had not seen the attack. He said he closed the kitchen door and left water, biscuits, and a mandarin for the girl before driving home.
After showering and washing his clothes, he dumped the murder weapon which was never recovered.
The woman's body was found when her partner came home later that morning to check why she had not arrived at work.
He found the daughter crying and upset.
The woman was found lying face down in the kitchen, and police were called.
The killer was found driving on Marshlands Rd at 12.25pm.
Gottermeyer admitted the attack, and told officers: "I'm not a very nice person."
