Police have dropped apprehended violence order proceedings against NSW Labor general secretary Jamie Clements, but pressure is mounting on Labor leadership to break ties with the political kingpin.

Mr Clements was accused of pushing party staffer Stefanie Jones against a wall and trying to kiss her last year.

The matter was due to be heard in open court today but was withdrawn, with Mr Clements agreeing to an undertaking he “not contact Ms Jones… makes any disparaging or derogatory comments about her… or approach her”.

Mr Clements denies anything inappropriate ever took place.

He released a statement today saying he was pleased with the outcome, but that the deal was not an admission of guilt on his part.

"I have cooperated fully through this process and am pleased it has reached a resolution which allows all involved to move forward," the statement read.

"I have always contested the version of events which has been publicly reported and the agreement reached today is without admission on my part.

"Having had discussions with my family and colleagues, I have decided this is the best way to move forward and focus on the challenges of 2016."

Mr Clements is a kingmaker within the Labor Party, directly responsible for the elevations of federal leader Bill Shorten and his NSW counterpart Luke Foley.

The job is critical during election campaigns and has previously been filled by heavy hitters including Graham Richardson and Senator Sam Dastayari.

Today Mr Shorten refused to comment, saying the matter was for the NSW Labor branch.

But, coming off the back of the Jamie Briggs scandal, it is understood NSW frontbench MPs have approached Mr Foley and urged him to pressure Mr Clements to resign.

Mr Clements is also being investigated by the Electoral Commission for allegedly illegally accessing the electoral role on behalf of union boss Derrick Belan.
