Which government department is responsible for enforcing the Privacy Act?

The Office of Privacy Commissioner is the correct answer because it is specifically established to ensure compliance with the Privacy Act. This department's role includes overseeing the protection of personal information, handling complaints regarding privacy breaches, and providing guidance on the implementation of privacy policies. The Office also raises public awareness about privacy rights and responsibilities, making it essential in enforcing the Privacy Act and ensuring individuals' privacy is respected and maintained in various sectors.

The other departments mentioned do not serve this primary function regarding privacy enforcement. For example, the Ministry of Justice primarily deals with aspects of the justice system, including law reform and criminal justice, while the Department of Internal Affairs typically handles administrative functions related to government services and citizenship. Consumer Affairs focuses on safeguarding consumer rights and fair trading practices, which, although important, does not cover the specific enforcement of privacy laws.
