Readers tell the Herald that multiple Lime e-scooters are parked with their lights on this morning - signalling they've failed to lock.
Ordinarily, a rider locks a scooter at the end of a ride via Lime's app - ending their journey and ensuring no one gets a free-ride on their credit card.
"We are aware of some cases where customers are having difficulty locking their Lime scooters at the end of a trip and are currently looking into the cause," a Lime spokeswoman said.
"Customers are not being charged more than they should for their ride. However, if for some reason this does happen, we ask that riders contact customer support and we will refund any overcharges."
A Herald journalist arriving at NZME's Graham Street building was among those affected by the bug.
