The seven-time champion split with previous manager Penni Thow after three years on the books at her talent advisory firm Copper, and instead returned to working with long-time friend and ex-racer Marc Hynes.
Hamilton explained that his split with Thow's company was an amicable one, having come to the conclusion to go his own way after "a lot of deep thought" over the winter.
In reuniting with Hynes, who worked as a driver coach for Hamilton in his formative years in F3 and Formula Renault, he explained that he was in the process of putting his own team together, with diversity at "the heart" of its composition.
"It was a difficult winter, I would say, and a very unusual one," Hamilton said. "[There's been] a lot of deep, deep thought throughout December.
"Obviously, [there are] things going on with management, which is taking a lot of time to reshape. That's never an easy process, but it's all amicable.
"I'm now just working on rebuilding my own team, I have lots of things that I want to do and I know exactly what I want to do.
"It's about finding good people to add into your team, making sure that it's diverse. That's always at the heart of what I try to put in place."
