Police investigating the murder of Upper Hutt woman Lois Tolley say they have spoken to a number of people and made arrests on "unrelated matters".
Detective Senior Sergeant Glenn Barnett said the scene examination had been completed where Tolley was murdered at her home.
"In the course of our investigation, we have made three arrests on unrelated matters, and those individuals are now before the courts."
"The investigation team has also been examining CCTV footage captured in the area of Ms Tolley's Ward Street address."
He said there may be more CCTV from properties in the area, or from vehicles and he asked people who may have footage to get in touch.
