When an election is called, a date for the “close of roll” is also announced, on which date processing of enrolments and changes of details to the roll is suspended. Enrolment or change of details can be done online or by completing a form and sending it using regular mail, which must arrive by the deadline. Currently, the electoral roll records just the name and address of the voter, although in previous years occupation was also recorded.
