Supercars champion Kostecki has been absent from the grid so far this season, but announced on Monday that he will return to action with Erebus in Taupo.
This comes after months of allegations of bullying within the team, something that Adderton, a long-time sponsor through Boost Mobile, had publicly called out while also criticising both the team and championship for their handling of the situation.
Following the announcement of Kostecki’s championship return, Adderton revealed that Erebus had demanded the Australian remove brands from his helmet that had supported him over the winter.
