The number of Aucklanders using the city's rail network is at record levels, with 11 million trips in the past year.
The figure is the highest annual number of passengers ever to use the network.
Auckland Transport chairman Lester Levy said 5000 more passenger journeys were being made each business day compared to a year ago.
When the Britomart Transport Centre opened in 2003, 2.5 million trips were made on trains each year.
New electric trains are due to be introduced on the network in a few weeks and Levy said the jump in passenger numbers was pleasing given the disruptions due to electrification work.
"We are making strides with an ageing fleet of diesel trains which are now 60 years old," he said.
"Just imagine what we will do with new trains."
