Police says they have had a great public response after releasing a picture of a knife that was used to kill a Wellington mother.
Rongmei Fan, known as Mei, was savagely attacked in her Miramar home on November 8, hours after dropping off her children at school.
Her body was discovered by a friend two days later.
Wellington police yesterday released a picture of the 32cm knife with a wooden handle with the word `CARVER' stamped into the base which was used to kill the 37-year-old.
Detective Senior Sergeant John van den Heuvel said while the image of the knife might be upsetting for some, knowing where it came from was key to finding the person responsible for killing Ms Fan.
