The machines in the central city are ageing and fewer of them have been able to read credit cards.
Delays in getting machines fixed were due to supply-chain problems, Dunedin City Council infrastructure and development general manager Simon Drew told a recent infrastructure services committee meeting.
Sourcing items such as batteries was increasingly difficult, a council spokesman said.
Inclement weather also affected both machine performance and the council’s ability to service electronic equipment.
"We have now received a batch of batteries, so the number of non-operational parking meters has reduced significantly," the spokesman said yesterday.
The council is to consider options for meter replacement by the end of this year.
Some meters have been accepting only coins and payment can also be made through the PayMyPark app.
The council said last month customers who appealed infringement notices due to the credit card option not being available were advised of the two other payment options, "but we also consider each explanation on its merits".
