A transport export says any regulation around drink driving on e-scooters would be extremely complex. 

A study by Auckland City Hospital on e-scooter injuries has prompted another call for a zero alcohol limit for people riding them.

The study, published in today's New Zealand Medical Journal, reveals 180 patients were admitted to the hospital's emergency department in the first five months of e-scooter use in Auckland.

Senior Transport Engineer for Transport Consultancy firm Viastrada Glen Koorey told Simon and Phil the regulation around low powered vehicles is broad, and changes around intoxication would have widespread ramifications for other transport modes.
