The New Zealand Shareholders' Association is not against increases in directors fees and executive salaries but wants them to be in line with company performance.
Chairman John Hawkins said the association generally supported fee increases and only occasionally opposed them.
"I don't think that anyone has an issue with sharing the rewards among the participants," he said.
"Where we do have a problem is when a company is performing poorly and the directors' fees and chief executive salaries are out of kilter with that."
Last year the association opposed three companies' plans to raise their fees.
It successfully opposed fee increases for resins company Nuplex, and when fishing company Sanford went about raising its fees, the association succeeded in having the planned increase cut by half.
In the third case, the association was unsuccessful in contesting a fee increase for SkyCity's board.
Opus, whose origins lie in the former Ministry of Works, has strong links with Malaysia.
The company, which has a market capitalisation $314.7 million, is 61 per cent owned by Malaysia's Opus Group Berhad, which is a unit of UEM Group Berhad, an engineering based conglomerate.
UEM is a wholly-owned unit of Khazanah Nasional Berhad, an investment arm of the Malaysian Government.
