Auckland Transport has backed down and made changes to a bug that freezes money on HOP cards for about 16,000 users.
Following public and political criticism, Mayor Phil Goff said AT has come up with a "fair outcome" to the HOP card rule that sees balances disappear if people top-up their HOP card online and do not tag on within 60 days.
When Goff raised concerns about the bug two weeks ago, AT dug in its heels and refused to fix the problem. A day later, Goff and senior councillors gave AT bosses a sharp reminder they are there to serve the people.
Goff says the outcome will see AT put an online warning up front telling people they need to tag on within 60 days.
AT had also agreed to put a system in place for people who do not tag on within 60 days to get an automatic refund back to their bank account and an email confirming the refund, he said.
