Electoral rolls were compiled during general and provincial election years. They listed the names of individuals from each electoral district who were qualified to vote. Everyone eligible to vote was required to register on the electoral roll by law, even if they did not intend to exercise that right. The rolls can act as valuable census substitutes, particularly in countries like New Zealand where census records are not always available.
The 774,758 records in the New Zealand Electoral Roll collection allow you to pinpoint the location of your ancestor in 1925, and lists their address and occupation.
