Green MP Kevin Hague today said Ms Wilkinson's failure to implement all the recommendations compromised her credibility.
"Evidence before the Royal Commission now shows that the current minister quashed suggested improvements to the health and safety of those in the underground mining industry,'' he said.
"The Government should implement the safety recommendations from the 2008 Department of Labour Discussion Paper now.
"If Ms Wilkinson is an impediment to improving mine safety, then surely she should step aside.''
Labour spokeswoman for labour issues Darien Fenton also called for Ms Wilkinson's resignation.
"The minister needs to admit that she made a mistake when she ignored recommendations to introduce improvements in small mine safety in October 2009, including a system of mine check inspectors,'' Ms Fenton said.
"Her answers to date give no confidence that she recognises the gravity of her decision.''
Ms Fenton said the current system was not working and the Government needed to act to prevent further tragedies like that at Pike River.
"The minister needs to prioritise the safety of miners and get her department into gear to follow through on her recommendations.''
