Porirua police have charged a 38-year-old man with the murder of Tawa woman Amanda Dawn Taufale.
Ms Taufale, 33, was found dead at her home in the northern Wellington suburb earlier on Thursday.
Detective Senior Sergeant Mike Oxnam says the investigation team is still working hard to understand the exact events leading up to Ms Taufale's death
He says at this stage, the police are not looking for anyone else in connection with her death.
Police are still appealing for anyone who has seen a late model blue Toyota Hatchback, registration GMB108, to come forward.
On Friday officers will canvass train commuters at Takapu Railway Station for any sightings of the car.
