Taxis will be banned from using Auckland's Grafton Bridge during the day after repeatedly breaking the speed limit during a trial.
Before the trial, the only vehicles allowed to use the bridge between 7am and 7pm were buses and bicycles.
Auckland Transport launched the trial to give taxis 24-hour access to the bridge to improve links between the CBD and the hospitals and Newmarket.
The trial began in September and was due to run for a year.
However, Auckland Transport today announced the trial would finish at the end of the month after taxi drivers failed to adhere to strict conditions, including a 30km/h speed limit and a ban on overtaking cyclists on the bridge.
