The 31-year-old, who is visiting New Zealand before heading to Melbourne for the Australian GP, drew the attention of police after he published two videos of himself driving a Harley Davidson motorcycle on an Auckland motorway.
In one video, which he sent to his thousands of followers on photo and video sharing app Snapchat, Mr Hamilton shot a clip of himself heading down a motorway entrance prior to merging with other vehicles on the highway.
Another video shows Mr Hamilton as he is driving. It then pans over his shoulder to shoot the traffic behind him.
Police said today there was not enough evidence to show the racing driver star had actually been holding the cell phone at the time.
The 31-year-old may have had a hands-free device attached to the bike, which is legal, they said.
"Auckland City Police will be taking no further action in relation to recent media publicity about Lewis Hamilton and his motorcycle journey in Auckland," police said in a statement.
"The video footage available does not provide us with sufficient enough evidence that an offence has occurred. We would like to reiterate our earlier statements that police take the issue of mobile phone use while driving or riding very seriously, it is a significant distraction and a major risk to all road users."
Using a mobile while driving became illegal in November 2009 although continues to be an issue on New Zealand roads.
Mr Hamilton attracted the spotlight earlier this week after he tweeted a critical message of SkyCity Casino to his 3.2 million followers on Monday night.
"Don't ever go to sky city casino in Auckland, they treated me like dirt," he wrote. "Can't believe how rude they were. Worst casino experience ever."
The driver has since deleted his tweet.Using a mobile while driving became illegal in November 2009 although continues to be an issue on New Zealand roads.
