Harry Hayles, 47, was shot in the chest by a masked gunman outside his home in Evelyn Gardens shortly after 8.30am on Tuesday 3 April.
His 18-year-old daughter was also seriously injured in the attack when she was shot in the hand and stomach.
A red van found burnt out nearby is understood to be linked to the shooting.
A 33-year-old man has been arrested and question in connection with the attack, but has since been released on bail pending further inquiries.
Detective Chief Inspector Alan Little, the officer leading the investigation, said police still needed assistance and information from the community to make progress.
"We will be asking people specifically about a Red Renault Kangoo van, which is believed to have been used by gunmen," said DCI Little.
"This van was seen in the area prior to the attack and was later recovered after the shooting, having been set alight at Rosapenna Court."
He said detectives will also be asking people if they noticed the van in the Evelyn Gardens area between 8am and 9am on the day of the shooting, or if they saw it being driven to Rosapenna Court and set on fire.
DCI Little added that anyone who saw the van being driven or parked in north Belfast before Tuesday 3 April should contact police.
