The Melbourne-based driver said he's looking forward to the forthcoming season with Brad Jones Racing.
“I'm thrilled to be joining BJR as co-driver to Nick,” said Randle.
“It's a very exciting time. I have to say a huge thanks to Brad and Kim for the chance to be a part of their organisation. They're a team with so much history in not only Supercars but in Australian motorsport.
“I feel that the experience of competing in my first Supercars enduro campaign, as well as making my wildcard debut at Tailem Bend last year, will put me in good stead for the upcoming season of endurance.
“I'm very focused on getting behind the wheel of the BJR #8 Holden Commodore and delighted to be teaming up with Nick. I've known Nick for many years and are sure we are equally as hungry to get the results the team deserves.
