The Electoral Roll Control Centre, shown here in 1981 with manager Graeme Wilson (facing the camera), was set up by the Post Office after it took responsibility for maintaining the electoral roll. Under Post Office management a system of confirming each entry every three years was introduced. The board to the left was used to record the number of registered electors in each electorate and to note ongoing work with local registrars of electors. The Post Office was also an early user of computers: the terminal on the left was hooked up to a mainframe computer located offsite, and inputting of data took place all over the country.
