Auckland Council bungled the amount of money owed by veteran activist Penny Bright, who is facing court action and the seizure of her home over years of unpaid rates.
Papers presented by the council at the Auckland District Court show it was owed more money by Ms Bright than the amount over which it had earlier sought and gained court judgment.
Ratepayers have missed out on $3000 as a result of the error - one of two judgments obtained by the council was for $6500 rather than the $9438 it turned out she owed, the papers submitted by the council showed.
The judgment was one of two, with Ms Bright found to owe a total of $33,000 in unpaid rates and penalties which she was yesterday in court to challenge.
She last paid rates in 2007, refusing to do so since because she says council doesn't adequately explain where the money goes.
