Bernie Monk, whose son Michael was one of the 29 miners who died, said today the company had been happy to take millions of dollars out of the West Coast when things were good, but it just walked away when it suited them.
"If companies like Oil and Gas want to do this, well, God help New Zealand," Mr Monk told Radio New Zealand.
"They've done only what they had to do but this was a moral right to put money into Pike River. They didn't mind investing in them at the time and taking what profits came from it but if something goes like this they just run a mile and I just can't believe it."
He said legislation needed to change so companies could not get out of paying reparation.
"These multimillion-dollar companies are accountable for the deaths. If some of these blokes making calls had people underground I don't think they'd be doing the same thing."
NZOG chief executive Andrew Knight told Radio New Zealand the company had already done enough.
"If you look at what we've done, New Zealand Oil and Gas stepped up and put $25 million into Pike River post the explosion and that's gone in in a variety of ways.
"We believe we've done the right thing and I think that's what our shareholders are telling us."
Mr Knight added that the matter had been considered from a moral perspective.
"The reason the discussion was being had at our shareholder meeting was on that basis," he said.
"We had a shareholder who felt it was important that the meeting considered the dilemma and put it in the context of what we've already done so I think it wasn't just a legal discussion, it was moral."
At the NZOG annual meeting yesterday, a second motion, put by an individual shareholder, was also lost.
It read: "Shareholders express their dissatisfaction with the way in which the directors managed the company's investment in Pike River Coal Ltd and the company's response after the explosion in November 2010."
