Detectives are still looking for four men in relation to the weekend killing of a woman in Upper Hutt.
The body of 30-year-old Lois Tolley was discovered at her Ward St flat about midnight on Friday.
Police are looking for a knife and a gun they believe were used to kill her, and for four men in their 20s who were seen leaving the property wearing dark hooded clothing.
Detective Senior Sergeant Glenn Barnett said a large team of investigators was working hard to resolve the case and a large number of people had been spoken to.
But he said there were still people with information who were yet to come forward.
