Police investigating the disappearance of a Whanganui woman continue to focus on a house in Feilding, a green van and her phone and internet use.
Marice McGregor, 45, was last seen collecting pine cones at Lismore Forest, north of Whanganui, on 19 April.
The Mitsubish van seen near Ms McGregor has been found and forensically examined. Detectives have been at a house in Feilding linked to that vehicle again on Wednesday.
Police are still appealing for any sightings of the van on State Highway 4 on 19 and 20 April.
They are also trying to build a picture of the missing woman's communications by phone, email and on websites.
Police will not say whether any friendships Ms McGregor may have developed on social networking sites are important to the case.
Detective Senior Sergeant Gwynne Pennell, told Morning Report police are looking at who could have been driving the vehicle.
Ms Pennell said Ms McGregor communicated a lot with people using the internet and her cellphone.
