[6] The borough form of government used by North Haledon is a "weak mayor / strong council" government in which council members act as the legislative body with the mayor presiding at meetings and voting only in the event of a tie.

[40] In 2013, Mayor Randy George was criticized by residents for his use of two borough-owned generators in the persistent electric outages during the days following the devastation of Hurricane Sandy to provide power to the refrigerators in his ice cream store, while Police Chief Robert Bracco had used another municipal-owned generator to provide power at his home.

[48][49][50] Prior to the 2010 Census, North Haledon had been part of the 8th Congressional District, a change made by the New Jersey Redistricting Commission that took effect in January 2013, based on the results of the November 2012 general elections.

[51] For the 119th United States Congress, New Jersey's 9th congressional district is represented by Nellie Pou (D, North Haledon)[52] New Jersey is represented in the United States Senate by Democrats Cory Booker (Newark, term ends 2027) and Andy Kim (Moorestown, term ends 2031).

The 221st district's seat in the State Senate was vacated upon Nellie Pou's swearing into the U.S. House of Representatives.

[55] As of 2025[update], Passaic County's Commissioners are: Bruce James (D, Clifton, 2026),[56] Deputy Director Cassandra "Sandi" Lazzara (D, Little Falls, 2027),[57] Director John W.

[94][95] For ninth through twelfth grades, public school students attend Manchester Regional High School, which serves students from Haledon, North Haledon, and Prospect Park.

The district participates in the Interdistrict Public School Choice Program, which allows non-resident students to attend the district's schools without cost to their parents, with tuition paid by the state.

[98] North Haledon residents had successfully voted in 2003 to leave the district, choosing to send their high school aged students to Midland Park High School in nearby Bergen County, New Jersey.

In August 2004, the New Jersey Supreme Court decided against North Haledon, citing that the town's exit from the district would shift the ethnic and racial balance of the high school.
