Mr Harris' second-largest charge was $91,317, spent on confidential legal advice.
With that advice from outside professionals, the council had been able to identify some "very significant savings" within the organisation so it could cut its total spending.
"I've been in the job for 12 months and have been totally focused on driving efficiencies in the organisation and we have a plan now to take $15 million per annum out of the spend of the organisation," he said yesterday.
"So my focus has been on the big efficiencies drive and as part of that, I've had to take advice from a number of professionals, both legal and financial, in order to assist me to drive that level of change."
He believed his office's spending was "very reasonable" for an operation of its size.
Mr Harris, who makes $360,000 a year, also spent $11,353 on meeting expenses and hosting costs.
The budget list said those costs related to room bookings, audiovisual equipment and catering.
The chief executive's office also spent $5538 on travel - including flights, accommodation and taxis - and $1488 on printing and stationery. Pens, flowers and a Koru Club membership were among Ms Hardaker's $92,000 of expenses.
