Friend Carl King confirmed Bennett's death to the Herald.
He said he was with Bennett and several other motorcyclists as part of an Anzac Day rally.
After the incident he and several others tried to revive Bennett, he said.
King posted a video on Facebook showing him and at least eight other motorcyclists travelling in convoy through Auckland.
Social media personality Sam's Life has taken to Facebook to acknowledge the death of his friend: "Rest easy Johnny Danger, lost for words."
Max Key also acknowledged Bennett's passing, sharing a number of photos of the pair together, as well as one with former Prime Minister Sir John Key.
"Some absolutely shattering news today,'' Max Key wrote.
"You taught me how important it is to not take yourself too seriously and to live life to the fullest! Was so epic causing mischief with you and I hope you swig hard up there. RIP my friend.''
Bennett can be seen picking up his helmet and fastening it before hopping on to his bike.
Last November, Bennett posted a photo of his new motorcycle licence; clearly excited to get it.
He told fans: "My new licence photo, finally got my full bike licence! I didn't know I was getting a new pic so I had no time to think up something, this will do for now. Time to get a Harley now.''
Bennett, of Whangaparaoa, has a huge following of fans on social media sites.
He has up to 204,000 followers on his Instagram page and a quarter of a million on Facebook - and numerous tributes have been posted on both sites already.
The amateur stuntman and comedian is hugely popular with Kiwis and also has an international following; with his videos attracting comments from fans from all around the world.
In 2015, he was found guilty of causing a criminal nuisance after video footage surfaced of him "surfing'' on a taxi as it went over the Auckland Harbour Bridge in 2013.
The taxi-surfing video - which went viral on social media and featured on international news sites - shows a man climbing out of the vehicle's passenger-side window and precariously clinging to the Reliable Cabs sign on the roof.
Bennett's beer brand "Dangers Beer" was pulled from the shelves of a major New Zealand supermarket chain, following a backlash online.
