The mouth, esophagus, stomach, and intestines are part of the gastrointestinal tract. Gastrointestinal is an adjective meaning of or pertaining to the stomach and intestines. A tract is a collection of related anatomic structures or a series of connected body organs.

Tolls were originally 2/6 (2 shillings and six pence: approximately $5.46 in 2014) per car but were reduced to 2/- (2 shillings: approximately $4.27 in 2014) after 15 months of operation. The toll remained at 2 shillings until New Zealand changed to decimal currency in July 1967, when that amount became 20 cents in the conversion. Tolls were increased in 1980 from 20 to 25 cents (approximately $1.17 in 2014) by Prime Minister Robert Muldoon, and this contributed to the National Party's loss of the 1980 by-election in the East Coast Bays electorate. Tolling was later made north-bound only before being discontinued on 30 March 1984, and the booths were removed. This was in line with political commitments that tolls would be charged only until construction costs were paid off.
