The Department of Internal Affairs (DIA) is a New Zealand government agency established in 1840, making it one of the country's oldest public service institutions. It operates as a central hub for government services, managing functions that span digital identity, vital records, citizenship, passport issuance, gambling regulation, and the administration of anti-money laundering legislation. The department also oversees Archives New Zealand, the National Library of New Zealand, and the New Zealand Gazette.
DIA's technical work centres on digital identity, digital transformation, and online service delivery. A key product is RealMe, a verified digital identity service enabling New Zealanders to securely access government and private-sector services online. The department's technology teams support the infrastructure behind passport issuance, births, deaths and marriages registration, charities registration, and lottery and community grants programmes.
Beyond its operational mandates, DIA administers a broad range of regulatory and community-facing functions, including gambling regulation to protect vulnerable populations, and ceremonial services such as the congratulatory message programme for significant birthdays and wedding anniversaries. The department has signalled a commitment to innovation, cultural responsibility, and authentic engagement with Māori and Pasifika communities.
