Hamilton's deal runs out at the end of the 2023 season, with the seven-time champion locked in talks with Mercedes but progress over agreeing fresh terms is slow.
It's not the first time that a Hamilton contract renewal with Mercedes has dragged on throughout a season, with a one-year deal for 2021 only being penned in February of that year, just before pre-season testing.
There have been suggestions that the delay is due to Hamilton demanding more money than Mercedes are willing to offer, but Wolff dismissed the idea.

Hamilton's contract talks
"We want to do it super, every detail, and sometimes you can have a situation where everything is carved out," Wolff told media including RacingNews365.
"But this is not a money discussion at all. It is about the future, it is what is it that we want to do right and optimise.
"We're not talking anything anymore about duration, money all of that. It is just other topics."
As negotiations continue there was a potential flashpoint between Hamilton and Wolff during the Austrian Grand Prix, where the Briton was complaining about the car and various track limit violations, with Wolff intervening to tell Hamilton to "drive the car."
But Wolff has dismissed this as any sign of frustration or tension between the two.
"You should hear us talking on the phone and meeting each other, that is nothing!," he said.
"I think we've had a bad spell of a weekend, all of us in the team, and that just makes us stronger."
"We had a lot of discussion about track limits and whether they were enforced or not.
"I felt that I wanted to just make sure that we were getting the best out of a package that didn't perform and just give it the best shot that we had."
