People can ride free on this driverless electric shuttle around the Christchurch Botanic Gardens this weekend.

A "smart" shuttle with no driver will give visitors a free ride around the Christchurch Botanic Gardens this weekend.

The Ohmio Lift shuttle is owned by Christchurch Airport and was developed with Ohmio Automotion Limited, which the Christchurch City Council gave a $50,000 grant.

"This Kiwi-made vehicle is autonomous, electric, 3-D printed and can carry up to 15 people," airport chief executive Malcolm Johns said.

The shuttle has been tested on private roads around the airport.

Between 9.30am and 6.30pm on Saturday and Sunday, people can have free rides on the shuttle from the old Tea Kiosk, next to the children's paddling pools and playground.​
