The KDC applies two types of rates penalties. A 10 per cent "instalment" penalty is applied if landowners fail to make quarterly rates payments on time. "Further" 10 per cent penalties are placed on overdue rates accounts every six months.
Mr Robertson said "further" penalties were cancelled if landowners brought their rates accounts up to date by June 30 this year.
"The High Court was clear the validated rates were payable. We expect people waiting for the court decision to accept they have to pay their rates."
A total $4 million owed in KDC rates arrears on June 30 included up to $2 million on Maori land and other arrears not associated with the rates strike.
Told of Mr Robertson's response, Mr Rogan said the commissioners had turned down a goodwill gesture by ratepayers opposed to the unjust imposition of penalties on rates that were acknowledged to be illegal for years until retrospectively validated by Parliament.
"If the commissioners remitted all the penalties many ratepayers would pay their historical rates and the tension between the ratepayers and the council would be markedly eased," he said.
The Mangawhai association is preparing submissions for a case it is bringing to the Court of Appeal to decide whether councils can set and assess rates to recover illegal debts.
Mr Rogan said a date had not yet been set for the hearing but the association was hoping it would be before the end of the year.
