"We had difficulty approving the whole lot at this stage because it's not backed up by performance."
Hunt said the company argued its total return to shareholders (TRS) was better than many, but he said that ignored the fact that since 2007 the TRS has fallen.
SkyCity's operating performance had been flat since 2008, Hunt said.
The association would have representatives at the annual meeting. "What we're hoping is that they back down and then we could say something nice about them."
Many of the association's members were unhappy "and what we've come up with is what we feel is a fair compromise".
"We're saying, hey, let's reward performance, don't let's be wrong about that, but at the moment we don't see its justification having large increases based on just because other people are doing it," he said.
"We've got to stop that practice."
A spokesman for SkyCity said: "The resolution hasn't changed and the company still believes it is a well considered position that we are happy to put to shareholders on Friday."
