"It's a chance they take."
Glen Eden mum and Plunket car-seat trainer Rochelle Cave and her daughter Isla attempted three journeys on behalf of the Herald on Sunday this week.
Taxis United and Cheap Cabs said they did not have them and Auckland Co-op Taxis provided them for airport fares only.
Of three companies which said they could provide a proper seat for an extra fee, only one - Affordable Choice Cabs - actually could do so.
A Budget Taxis driver had an appropriate seat for Isla, but the vehicle did not have the anchor bolts installed to secure the seat safely.
Budget Taxis complaints officer Francis Raman said they trained their drivers in installing the seats, but agreed the driver had obviously not been trained. More training was planned.
Green Cabs showed up with no car seat, a mistake the company's general manager Karen Malfait blamed on the driver not reading the request properly. All drivers would be reminded to do so.
Waitemata Plunket car-seat manager Simone Budel said taxi drivers should ensure all passengers were safely restrained.
"The cost of a car seat shouldn't stop them. We would prefer taxi drivers kept their passengers safe, no matter what their age."
