Following talks between the pair, as well as discussions with the team, in the wake of a controversial Monaco GP, Hamilton says that the focus has shifted firmly to the future.
"We spoke after the race and like friends, we have ups and downs," said Hamilton, who trails Rosberg by four points in the drivers' championship.
"We have known each other for a long time and it is done and dusted.
"We look forward to working together to help the team win the constructors' championship."
Mercedes held a team dinner in Montreal on Wednesday night at which both drivers attended, and Hamilton says the atmosphere within the Brackley-based outfit remains positive despite the recent troubles.
"Collectively with the team, me and Nico spoke and we individually spoke to the team, nothing has really changed," he said.
"The team has done a great job in supporting us in the way it is run with Paddy [Lowe] and Toto [Wolff]. Their support for both of us is great.
"We are full steam ahead. We had dinner together with the team yesterday and things are better.
"We are going from strength to strength. People have ups and downs so it is no different from years we have been racing together.
"We move on. There is a long way to go and we are looking forward to that battle."
