electoral redistribution prior to the . The character of the electorate changed significantly and it became urban again. In the 1967 electoral redistribution, the North Dunedin electorate moved south, losing the Port Chalmers Borough once more to the re-established Oamaru electorate but gaining area from Dunedin Central. In the 1972 electoral redistribution, Port Chalmers came back to the Dunedin North electorate. There were only minor boundary changes in the 1977 electoral redistribution, but a significant urban shift to the south occurred through the 1983 electoral redistribution, when the Dunedin Central electorate was subsumed by Dunedin North and Dunedin West. There were further boundary changes through the 1987 electoral redistribution. The 2013 redistribution saw the electorate expand to include Palmerston, Macraes Flat, Moeraki, Hampden and Herbert-Waianakarua. In its final shape from 2014 to 2020, the Dunedin North electorate covered the northern half of the city of Dunedin. It was bordered by Waitaki in the north, Dunedin South in west, south, and south-east, and the Pacific Ocean in the north-east. The electorate covered what is the equivalent of the Waikouaiti Coast-Chalmers ward of the Dunedin City Council outside the actual urban area of Dunedin. This included the population centre of Waikouaiti, Karitane, Waitati, Seacliff, Warrington, Port Chalmers, Sawyers Bay, Roseneath, and Aramoana. In urban Dunedin it covered most of northern, central and western Dunedin. This included the city centre and the suburbs of City Rise, Pine Hill, Dunedin North, North East Valley, Opoho, Ravensbourne, Mornington, Roslyn, Maori Hill, Leith Valley, Kaikorai Valley, Brockville, Halfway Bush, and Wakari.

The electorate has the highest proportion of persons aged 15 to 19 in the country, with 14.1%. It also has the highest proportion of people on a student allowance (8.8%), employed in the education and training industry (11.7%), and employed in the health care and social assistance industry (12.3%). The Dunedin North electorate has a low rate of enrolment compared to New Zealand as a whole. As of 31 May 2012, 78.4% of the estimate eligible population was enrolled to vote, compared to 92.8% nationally. The figure was brought down by the low number of people aged 18 to 24 enrolled — less than half (47.5%) of the estimated eligible population was enrolled, compared to 75.2% nationally.
