The Crown Law Office (Crown Law; Māori: Te Tari Ture o te Karauna) is the public service department charged with advising the New Zealand Government on legal affairs, representing the government in appellate cases, and overseeing the prosecution of criminal offences before the courts.

The offices of the attorney-general and solicitor-general are the principal legal advisers to the New Zealand Government, and act as the Crown's representatives in court.

During this period the roles and responsibilities of the attorney-general and the solicitor-general were the subject of some debate and clarification by the Supreme Court.

[3] The Crown Law Office was formed to provide legal and administrative support to the solicitor-general.

The main purpose of the Crown Law Office is to assist the attorney-general and the solicitor-general in carrying out their legal responsibilities and obligations.
