He joins incumbents Paul Dumbrell, Will Brown and Nathan Morcom, with Eggleston Motorsport purchasing the Triple Eight-built Commodore that won Bathurst in 2016 from Tekno Autosports for the 28-year-old's use.
“I'm really excited to join Super2 with a team like EMS,” Storey said.
“We have a great relationship from the past two seasons in GT and along with my long-term sponsors, Autex, I am excited about the new challenge.
"It has been something I've worked towards for a few years now and to progress into Super2 after winning the Australian Endurance Championship last year is a great step for my career.
“I would like to especially thank Peter Hackett for giving me the opportunity in 2016 and 2017 to help prove I have the ability to take this next step in my career, along with all my supporters for staying with me.”
The team is running the maximum-permitted number of cars at four, and is also providing technical support to newcomer Brenton Grove, under the Grove Racing banner.
New Zealand-born Storey has starts in a variety of single-seater classes on his CV, including GP3, Formula Renault 3.5, British Formula 3 and Formula Renault 2.0.
In his maiden international foray, he was Daniel Ricciardo’s team-mate in the Formula BMW Asia Series in 2006.
Before switching to GT racing with Eggleston Motorsport in 2016, raced in the NZ V8 SuperTourers Series across three seasons.
“Dom is a valued part of our EMS family so it’s great to have him step up into a Super2 car this season after a hugely successful past two seasons aboard the Mercedes AMG GT3 he drove with Peter Hackett,” team owner Rachael Eggleston said.
“He showed that he can mix it with the best professional GT drivers in the world and was regularly quicker than factory drivers.
“He has some New Zealand V8 SuperTourer experience too so driving one of our cars won’t be completely foreign and with his extremely dedicated and professional approach, both in and out of the car, I am confident he will get up to speed quickly and be scoring some very solid results from the outset.”
