Cameron could not be contacted last night, but Steve Thompson, who was Delta chairman during the last financial year, said while he understood the sentiment, the payout was part of a contract that had to be honoured.
The annual report came in a council agenda, released yesterday, for a meeting on Tuesday.
The report showed the company performance was steady, but included payouts and staff wages bound to anger critics of the company.
Cull released a statement at the same time as he was contacted by the Otago Daily Times.
He said when he was made aware of the payout he made his concerns clear to DCHL chairman Graham Crombie.
"I understand that executive salaries need to be market-based and that legally neither I nor the council can interfere in the operations or employment arrangements of the companies.
"However, I have sought and received assurance from Mr Crombie that he has worked with the companies to ensure that the employment terms and conditions for company executives show restraint while also being fair to employees."
Thompson said last night he was unable to discuss the composition of Cameron's payout.
"I can't do that.
"Every individual contract is confidential between the employer and employee.
"Payments that have been made are payments we have been contractually obliged to make, and so we made them."
Thompson said he could also not say whether there was a performance bonus in the payout, nor whether or not there would be any more termination payments to Cameron when he left his role as chief executive of Aurora at the end of the year.
On the expansion of the number of staff earning more than $100,000, he said the numbers reflected market reality in the energy industry.
"At the moment there's very high demand for skilled people."
Delta was doing a lot of work on the network, which had increased as pressure had gone on Aurora to replace its infrastructure.
"That is just the market price of getting people who are appropriately skilled and expert to do the work on the network that we need.
"Many of those were highly trained specialists, engineers and experienced line workers."
There was also an overtime element.
"Our staff work hard."
Thompson said he agreed with Crombie's response the company needed to ensure restraint while also being fair to employees.
The company wanted to do that, but needed to meet the market.
"I won't make any apologies for the market.
"We have a lot of work to do, and we have to meet the market.
"But we certainly acknowledge the sentiment expressed by the DCC, and DCHL."
