It will be another two years before Auckland Council has a single direct debit system for rates, making life difficult for some ratepayers in the meantime.
A council spokesman says the move to a single rating system is a "nine-legged beast" with the system still running off the eight former councils' computer system with an Auckland Council overlay.
Ratepayers are still on different direct debit systems used by their former councils.
Two ratepayers have contacted the Herald outlining problems with paying their rates by direct debit.
One North Shore ratepayer was upset at having an extra instalment taken out in the last financial year after being told the council was spreading payments over 12, not 11 months. She eventually got a refund.
