The 30-year-old ticket was sent to the ministry not long after it was issued, but Riwai has no idea why it has gone so long without being paid.
"Once it's been lodged with the Ministry of Justice, we would have very little control over that," she said.
But council has now decided to bring in debt collectors to tackle the pile of fines, a move Riwai said would be beneficial to customers.
"They won't have to pay that $30 court lodgement fee . . . obviously we will return some of that revenue to council quicker."
The move is expected to come in the next few weeks.
Riwai said it was not unusual for ticket repayment to trickle in over a long period of time. The majority of the unpaid tickets are from the past five years.
Council does not add overdue fees to the tickets, but Riwai could not say what the ministry might add.
"The one thing I would like to say is that if you get an infringement, just pay it please."
