Auckland Mayor Phil Goff has lambasted irresponsible e-scooter riders, as a new safety campaign is launched.
The "Scoot Safe" education programme aims to educate riders, after the introduction of 1000 scooters in Auckland and Christchurch.
Goff says a 10-kilometre an hour speed limit may need to be imposed.
"It's pretty hard to legislate against idiocy and stupidity, but I've seen a bit of that as well."
Nearly 150 e-scooter injury claims have been lodged with ACC.
