Four Tauranga taxis have been ordered off the road after they were found to be unsafe during a surprise sting.
The New Zealand Transport Agency teamed up with the police's Commercial Vehicle Investigation Unit in April to check taxis in the Bay of Plenty and Waikato.
They examined drivers' compliance with taxi rules, work times and logbooks, driver and transport licensing, as well as vehicle safety standards.
Taxis targeted in Tauranga, Rotorua and Hamilton had to undergo a mechanical examination and compliance inspection.
A total of 67 vehicles were checked, with the worst 10 vehicles ordered off the road due to mechanical defects - including four in Tauranga.
