Almost $217,000 of public money has been paid for taxis or buses in the past four years to shuttle stranded train passengers to their destination.
However, the figure spent each financial year is dropping and officials say it's evidence of an improving train network.
According to figures obtained by the Herald under the Official Information Act, the amount spent on alternative forms of transport dropped from $71,820 in the 2011/2012 financial year to $46,067 in the last financial year. The budgeted allowance for the 2015/16 financial year is $29,225.
AT Metro general manager Mark Lambert said Transdev had to provide a form of alternative transport when services were cancelled or delayed. Other modes of transport includes taxis and bus services.
"That's all about putting the customer first and particularly when you consider the Transdev contract goes back to around 2004 when we were still in the early days of redeveloping the rail network in Auckland."
