Lewis Hamilton under police investigation

British Formula 1 champion Lewis Hamilton is being investigated by New Zealand police after he used a cell phone while driving a motorbike in Auckland to video his antics.

The 31-year-old used video sharing app Snapchat to capture himself driving a Harley Davidson motorcycle on an Auckland motorway.

Police have been provided with copies of the footage and will be reviewing whether further action should be taken.

Police told Newshub they take a strong stance on any activity which places undue risk on the lives of any person on the road, and using a cell phone while driving is a significant distraction, especially on a motorbike.

The three-time champion made a surprise visit to the country on Monday, before heading to Melbourne for the Australian Grand Prix this week.

He has already drawn media attention after tweeting about receiving terrible service at the SkyCity Casino.

"Don't ever go to sky city casino in Auckland, they treated me like dirt. Can't believe how rude they were. Worst casino experience ever," it read.

The tweet has since been deleted.

A SkyCity spokesperson responded: "SkyCity is very sorry to hear Lewis Hamilton didn't enjoy himself at our casino last night -- we pride ourselves on providing an excellent level of service to all our customers. We are following up with Mr Hamilton to get further details of his experience."
