Lawyers were also called in to give advice on the damning V8 audit and terminating the contract for the event early.
The ongoing stoush between the Frankton Business Association and large retailer Forlongs over closing Commerce St for the Frankton markets on Saturday meetings has also required significant input from council law firm Tompkins Wake.

Waipa District Council spent $113,705 on advice over the Maungatautari ecological island project, south of Cambridge, as the ongoing stoush between landowners and councils over access continues.
Waikato Regional Council paid $492,202 to lawyers for advice on the water allocation plan variation aimed at managing the allocation and use of freshwater over all of the Waikato region. Numerous parties appealed against the plan to the Environment Court.

Waikato District Council spent $74,982 on legal advice over its refusal of a land resource consent to allow Raglan business Playground Events to operate events from its Te Uku property, and $44,215 on the large Contact Energy wind farm between Port Waikato and Raglan.
Waikato District mayor Allan Sanson blamed the majority of legal costs over legislation thrust on to them by central government.
"Everything we deal with these days has a large element of legality around it and it's a real problem. It's getting so difficult now you have to engage lawyers all the time."
Legal commentator Ron Pol said local councils could save large sums of money by relying on good in-house counsel rather than continuing to use large external law firms.
