Footage posted online has shown a Lime rider zooming around a Christchurch suburb with fireworks attached to the back of his scooter.
The video, posted to Facebook page Limes in Weird Places, shows him travelling on the e-scooter past laughing onlookers, with a cascade firework spewing sparks into the air behind them.
An administrator of the page said the video was taken in Christchurch.
It appears the rider is wearing a helmet and pants to shield him from the sparks, a choice that was noted by people on Facebook.
"This would be the first guy I've seen actually sticking to Lime rules and wearing a helmet," one person said.

Another pointed out the stunt was almost certainly a recipe for disaster.
"Fireworks mixed with Lime scooters - it's like the ultimate ACC claim."
Peter Gallagher from Fire and Emergency New Zealand (FENZ) wasn't impressed by the video.
"It's disappointing to see some people still using fireworks irresponsibly and putting themselves and our communities at risk of serious injury and even death," he told Newshub.
"Fireworks can be fun, but they can also be dangerous and pose a high fire risk, so it's vital that safety advice is followed."
He says fire crews responded to 47 incidents nationwide between 6pm on Guy Fawkes night and 6am the following morning, bringing the total number of fireworks incidents in the first six days of November to 109.
FENZ recommends lighting fireworks in wide-open areas away from flammable items, pointing fireworks at the sky rather than other people and keeping a bucket of water, hose or fire extinguisher handy.
They also say pyrotechnics fans should refer to their local bylaws around fireworks, as in many places they can only be lit on private property.
Lime announced on Tuesday it would be launching a new initiative focused on safety for riders and pedestrians alike.
"At Lime, we believe it's our responsibility to partner with cities, riders and residents to make sure everyone gets from point A to point B safely," CEO Toby Sun said.
The company has released instructional videos on scooter safety, bike safety and proper parking, and a safety fact sheet for riders. The fact sheet does not make reference to fire or fireworks.
