"We don't maintain staff time records for the requests but we estimate that these requests have taken between four and 100 hours per request, with requests for correspondence being the ones that take the longest time," he said.
Mr Harkness said costing out the OIA requests took into account that the work was often done by or at least reviewed by a senior member of council staff. "As such, a rough estimate of cost would be in excess of $20,000," he said.
Mr Laws said he used the Official Information Act when he was "unable to get the truth" from official council papers or meetings. He said they had revealed "the secret suggestion of council staff that the council could borrow or rate to fund the $32 million Sarjeant Gallery project".
The council has ruled that no ratepayer funds will be used and the project will be funded from external sources.
Mr Laws also said his OIA requests had delivered "the smoking gun" as to the malfunctioning wastewater treatment plant's design.
"It contradicts the ... line that decisions taken by my council led to the failure."
He added that his "council sources" had advised him there was no cost to filling any of his OIA requests other than the cost of photocopying paper and that the staff processing the requests were already being paid.
EDITOR'S NOTE: Mr Laws described this as "a nonsense story about a non-existent monetary cost". We are happy to let the Chronicle readers make their own minds up.
