A Facebook page dedicated to finding missing North Shore resident Denver Chance has made an appeal for dash-cam footage on State Highway 1.
Chance was reported missing on Sunday, February 24, after he was last seen around 3.30pm at the property where he rented a room in Mairangi Bay.
Earlier today, police said they had concerns about his safety and released a picture of his car heading south on the Southern Motorway near Drury.
Meanwhile, an appeal was lodged on the "Help find Denver" Facebook page for dash cam footage from anyone driving on SH1 after 3.30pm.
"We urge anyone travelling on SH1, Sunday 24th Feb, south or north bound (any time between 3.30pm and midnight)," the post reads.
