Premier Dominic Perrottet was asked on Monday about a complaint regarding Camden MP Peter Sidgreaves over branch stacking and the alleged bullying of an electorate office employee.
"So we received that complaint (and there's) two aspects of that," he told reporters on Monday."
"There is absolutely no place for bullying in any workplace environment and they (allegations) need to be dealt with appropriately, independently and in the best case scenario, confidentially," the premier said.
The issue was being dealt with by parliament's independent complaints officer who was appointed last year after the Broderick inquiry into bullying, harassment and sexual misconduct in NSW parliament offices, he said.
The latest development comes days after upper house Liberal MP Peter Poulos was dumped after it was revealed he'd shared explicit pictures of rival during a preselection battle.
The sudden vacancy in the Liberal Party's upper house ticket prompted Transport Minister David Elliott to throw his hat in the ring for the spot.
"I told the premier I would like to be considered," he told Sydney radio 2GB on Monday.
Mr Elliott, who is from the party's centre-right, announced his retirement last year after failing to secure sufficient support to keep his seat after a redistribution.
However with less than five weeks until voters go to the polls, the premier is under pressure to get more Liberal women into parliament.
When asked about Mr Elliott's chances, he failed to endorse him for the upper house spot.
"That's a matter for the organisation.
"They need to go through those processes and I expect them to do that as soon as possible," he said.
Treasurer and moderate powerbroker Matt Kean is pushing for a woman to fill the job.
"What I'd like to see is a female fill that vacancy," he told reporters.
"I think it's a great opportunity for a strong female candidate."
Potential candidates include the party's Women's Council President Jacqui Munro, as well as Melanie Gibbons who lost a preselection challenge in her seat of Holsworthy and upper house MP Shayne Mallard, who was dumped from the party's ticket.
The factional fracas comes just days after the government was caught up in another scandal when Damien Tudehope resigned as finance minister after declaring he owned shares in toll road owner Transurban, the company that operates most of Sydney's toll roads.
Meanwhile, the government announced on Monday it would offer incentives of up to $4000 to public school teachers, in a bid to encourage more to gain national Highly Accomplished and Lead Teacher accreditation.
Education Minister Sarah Mitchell said the accreditation would recognise highly effective, innovative and exemplary teaching and enable teachers to achieve salaries up to $120,000.
However, Labor's education spokeswoman Prue Car says it's "too little too late from a tired, 12-year-old government that is out of ideas and throwing money out the door five minutes before an election".
