Until 1965, the New Jersey State Senate was composed of 21 senators with each county electing one senator. After the U.S. Supreme Court decision in Reynolds v. Sims required legislative districts to be approximately equal in population (a principle known as "one man, one vote"), New Jersey entered a decade-long period of reapportioning.^[2] In 1965, the Senate was increased to 29 members, with larger counties given multiple seats and some smaller counties sharing one or two senators.

For the 1967 election, the map was organized by the 1966 New Jersey constitutional convention. Assembly districts were drawn by the New Jersey Apportionment Commission. Eleven new seats were added to the Senate, with county lines generally followed to create 11 single county districts and two multi-county, single senator districts. As a result of a New Jersey Supreme Court decision, several existing districts were split up into districts smaller than a single county. This was contrary to the apportionment scheme in the New Jersey Constitution.

• Mercer, Middlesex, Union, Hudson, Bergen, and Passaic counties gained one seat each.
• Essex County gained two seats.
• Atlantic, Cape May, Camden, Cumberland, Gloucester, and Salem counties gained one combined seat for a total of six.
• Burlington, Monmouth, and Ocean counties gained one combined seat for a total of four.
• Hunterdon, Morris, Somerset, Sussex, and Warren counties gained one combined seat for a total of five.
