Respected journalist Derek Round was killed after suffering a number of violent blows to the head.
The 77-year-old's body was found in his Wanganui flat last Thursday morning.
Police have been at the Campbell St address all weekend and a post mortem has revealed Mr Round was hit a number of times.
Detective Senior Sergeant Dave Kirby says members of the public have since come forward, having seen Mr Round's jaguar being driven later the same morning.
He says the car was seen in the Aramoho area, and police have spent today in that same location looking for some of Mr Round's missing clothes.
Police are collating sightings of the blue Jaguar owned by murdered journalist Derek Round, as they continue to investigate his death.
Police say they've examined his blue 1996 XJ6 and it's now important to build up a picture of where it was on Wednesday night.
Detective Senior Sergeant Kirby says locals are also helping with information.
"You could accurately say that most people in that area are quite shocked that something like this happened in their area or neighbourhood."
Police are also pouring cold water on reports of KGB and gang links.
They say the allegations are a red herring which have deeply upset Mr Round's family.
Detectives are concentrating on a search operation in rivers and reserves to find missing clothing.
They're still keen to find out what happened to a black leather vest, dark stonewashed jeans and a pair of fingerless gloves.
