Wellington's Mayor is considering taking the city's bus lanes back to the drawing board. 

People driving in bus lanes are Wellington City Council's biggest money grabber, raking in around $6 million in fines. 

A new bus lane on Cambridge Terrace caught tens of thousands of people exceeding the 50 metre maximum, worth a penalty fee of $150. 

Andrew Little told Mike Hosking he doesn't want bus lane cameras to be seen as a source of revenue for the council. 

He says there's a genuine question on whether they need to be designated bus lanes for 12 hours a day seven days a week.
