Auckland Transport is to start automatically refunding people who have topped up their Hop travel card balance online, but haven't tagged on using their card for 60 days, before the end of the year.
In an email to customers the public transport company said from December 20 the balance on dormant cards would be refunded to individual bank accounts.
The same applied to any pass that was not activated through an electronic gate or bus within a two-month window.
The move comes after public and political criticism over money frozen on Hop cards of about 16,000 users.
Customers found themselves unable to tag on buses and trains despite previously topping up their Hop card.
