Anyone paying their rates after Monday can expect a 10 per cent penalty.
The regional council allowed a grace period between October 20 and 31 to allow anyone who might not have been expecting the bill a chance to adjust and pay.
On October 19, the regional council had $43m in rates outstanding.
At the time, Pellew attributed this to the fact it was the first year for direct rates collection.
After Monday, in addition to the 10 per cent penalty fee, any outstanding rates payments will cause three reminder or warning notices to be sent to the customer.
If payment had still not been made by June 30 next year, the regional council would initiate collection action.
