Mayor Bob Parker said yesterday that Mr Marryatt had not been paid the balance of the raise, which remained with the council.
Labour's local government spokeswoman Annette King said Mr Marryatt should drop any thought of now accepting the pay increase.
"There was widespread criticism of the pay hike when it was initially awarded, which makes it even more unbelievable that Mr Marryatt is now suggesting he might take it after all,'' Annette King, Labour's Local Government spokeswoman said today.
"To suggest that he is somehow `owed' a huge pay increase - more than twice the annual rate of married superannuation - when hundreds of ratepayers continue to struggle with post-earthquake financial pressures, is beyond stupid.''
It remains unclear when, and if, Mr Marryatt will repay the extra cash he has already received.
Mr Parker said the matter of the $26,000 was Mr Marryatt's business.
