Businesses being left frustrated about transport changes in Auckland's city centre is being put down to poor communication. 

Auckland Transport has decided to remove all car parking on Karangahape Road and restrict the times on loading zones to allow room for a new bus service.  

Businesses say they've been given very little notice. 

Infrastructure New Zealand Chief Executive Nick Leggett told Kate Hawkesby that no shop owner should wake up and find their loading bays are all but gone. 

He says these things always become a problem because we don't engage properly in discussions right at the start 

AT has apologised to businesses for the communication around the change.  

It says there will be a grace period until December 11 for vehicles caught using the bus lanes at the wrong time.
