Former NSW deputy premier John Barilaro will give evidence before a parliamentary inquiry investigating how he landed a taxpayer-funded trade job in New York.
Labor says the public accountability committee has scheduled a series of hearings after brokering a deal with the government to release three large tranches of documents relating to the appointment of the former NSW Nationals leader.
"This is a victory for the public's right to know and it's a defeat of the government's attempt to cover up these documents and the information they contain," Labor's Shadow Treasurer Daniel Mookhey said on Thursday.
Mr Barilaro, who was last month announced as the state's Senior Trade and Investment Commissioner to the Americas, will finally give his side of the story to the upper house inquiry on August 8.
The committee held off calling Mr Barilaro until the government made public all the documents it requested about the controversial appointment.
Mr Barilaro relinquished the role less than two weeks after his appointment was announced, as the political fallout heaped increasing pressure on the Perrottet government.
The inquiry's hearings will resume on Wednesday when Investment NSW CEO Amy Brown will make a second appearance.
Another hearing will take place on Friday with multiple witnesses called including Mr Barilaro's former chief-of-staff Siobhan Hamlin, Department of Regional NSW secretary Gary Barnes as well as staff from Investment NSW.
Ms Brown previously told the inquiry she withdrew the $500,000-a-year job offer from her colleague Jenny West after the relationship between Ms West and the government became "irreconcilable".
Mr Mookhey says there are new lines of inquiry to quiz Ms Brown over, and questions remain about whether Investment and Trade Minister Stuart Ayres misled the parliament.
"Mr Ayres has some very serious questions to be answering," Mr Mookhey said.
"How (was it) possible that he could say in parliament that no suitable candidate was found, when he was told that Jenny West was the successful candidate - after a full recruitment process?
"He's either misled the parliament or he's misled the public."
Mr Ayres, who is in Mumbai with Premier Dominic Perrottet, told reporters on Thursday he had "absolutely not" misled the parliament about the recruitment process.
He said he had simply relayed information given to him by Ms Brown, adding he maintained complete confidence in her.
The escalating scandal has dogged the pair's trade mission and led to a daily barrage of heated questions.
Mr Ayres said suggestions Ms West was pushed aside from the appointment to make way for Mr Barilaro were not accurate.
"I want to reject categorically that any decisions made at the end of the recruitment process were designed or orchestrated to create an opportunity for John Barilaro, alright," Mr Ayres said on Thursday.
"That is a preposterous suggestion."
He insisted Mr Barilaro applied as a private citizen, he did not take phone calls from his former colleague, and his role as a former deputy premier did not give him a leg up into the position.
Mr Perrottet continued to defend the appointment, saying he believed the former deputy premier was the strongest candidate.
"I think John Barilaro was somebody who had that experience in NSW, and ultimately, from my advice was selected on merit in an independent process."
Deputy Opposition Leader in the upper house John Graham said Labor was now focused on Mr Ayres' role in the appointment.
"There are real questions about whether or not this appointment was indeed at arm's length," Mr Graham said.
Plans to recall the NSW Legislative Council on Friday - more than three weeks ahead of schedule - were scrapped after the government agreed to release the additional documents by Monday.
