"Given these uncertain times, we appreciate that our shareholders might prefer to approve changes to the fee pool on a more regular basis and in smaller increments than was initially proposed," said Aitken.
Hunt said he hoped other listed firms would act like Nuplex.
"[For] far too long we have seen massive increases in director and executive pay which has had no relationship to the actual performance of the company," he said.
Hunt said the Shareholders' Association had raised concerns with SkyCity over its planned directors' fee increase, but the firm appeared to be forging ahead with the vote.
"This is a substantial increase when everyone else is suffering and we think it's outrageous," he said. "I would have thought SkyCity would have at least been prepared to make a compromise."
Hunt said the association was going from company to company looking at the kind of fee increases firms were seeking for their boards.
"We're not knocking everybody - we're just knocking those that are wanting large increases without relativity to performance."
Hunt said the fact Nuplex had backed down showed shareholders had the power to force change in companies.
The chief executives of New Zealand's biggest listed firms and state-owned enterprises received an average pay rise of 14 per cent in the 2010 financial year, the Business Herald's executive pay survey, conducted earlier this year, showed.
For all New Zealanders, the average wage increase was just 1.7 per cent in the year to the December 2010 quarter, Statistics New Zealand figures show.
