Presumptive GOP nominee Nicole Malliotakis said she’ll institute a hiring freeze for all non-emergency municipal workers if elected mayor in November — and cut City Hall staffing by 10 percent.

The Staten Island Assembly Member ripped Mayor de Blasio for bloating city government to record-high levels, including with 264 special assistants at City Hall.

“It’s an astronomical number to say you’ve added 30-40,000 people to the payrolls. That’s an astronomical increase in bureaucracy that obviously was not needed under the previous mayor, and I don’t know why it’s needed under this mayor,” Malliotakis said during a press conference outside the gates of City Hall.

“The money could be better spent.”

The Citizens Budget Commission says the city payroll will hit 329,055 in fiscal year 2018 — an increase of more than 31,000 positions since de Blasio took office in January 2014.

A good portion of those jobs include teachers hired for the city’s expansion of full-day pre-kindergarten, one of Hizzoner’s signature initiatives.

But the CBC’s analysis included concerns about recent headcount increases at other agencies — including the Parks Department — and of civilian employees at the NYPD and Fire Department.

De Blasio called for a partial hiring freeze earlier this year, but the CBC said it’s “not an actual freeze and may or may not generate projected savings.”

“This is another pathetic attack from a candidate who is desperate to avoid talking about her votes against raising the minimum wage, her ties to the right-wing billionaires who brought us Donald Trump, or her support for turning the NYPD into Trump’s deportation force,” responded de Blasio campaign spokesman Dan Levitan.
