Attorney-General (New Zealand)

The Attorney-General is a political and legal officer in New Zealand. The Attorney-General is simultaneously a ministerial position and the chief law officer of the Crown, and has responsibility for supervising New Zealand law and advising the government on legal matters. The Attorney-General serves both a political and apolitical function. The current Attorney-General is David Parker.
Responsibilities and powers.
The Attorney-General has two main areas of official responsibility. Firstly, the Attorney-General has ministerial jurisdiction over the Crown Law Office, the Parliamentary Counsel Office, and the Serious Fraud Office. Secondly, the Attorney-General is the principal law officer of the Crown, responsible for supervising the state's administration of the law and for providing legal advice to the government. This includes upholding the rule of law and advising on compliance with international obligations. In the latter role (but strictly not in the former), the Attorney-General is assisted by the Solicitor-General, a non-partisan official. This is to reduce the extent to which the Attorney-General's actions on behalf of the state (as opposed to the government) can be influenced by their political allegiance.
A more complete description of the Attorney-General's powers can be found in the ministerial briefings prepared by the Crown Law Office (most recently in 2017), of which the Attorney-General is the responsible Minister.
At present, there is no statutory basis which establishes the office of Attorney-General, although the position is referenced by a number of other legal documents, such as the Constitution Act 1986 which allows the Solicitor-General to exercise the functions of the Attorney-General. The functions of the Attorney-General are also described in the Cabinet Manual.
There is no constitutional duty on the government to follow the advice of the law officers. The Cabinet Manual outlines the process by which the legal advice provided by the Attorney-General (and others) may be disclosed.
The position of Attorney-General is distinct from that of Minister of Justice, although the two posts are sometimes held by the same person, for example, Martyn Finlay who held both positions from 1972 to 1975.
History.
Historically, the post could be held either by a politician or by a senior jurist, but today, it is invariably held by a member of Parliament. The Attorney-General attends Cabinet, but the post is not the same as the Minister of Justice. The post of Attorney-General has existed since the separation of New Zealand as a distinct Crown Colony from New South Wales.
By tradition, persons appointed to the position of Attorney-General have been lawyers. Only two former Attorneys-General have not been lawyers, most recently Dr. Michael Cullen who held the post in 2005 and again from 2006. In November 1906, when Albert Pitt died, there were no suitable members of the legal profession in Parliament. Hence Joseph Ward appointed 
John Findlay to the Legislative Council on 23 November 1906 and appointed him Attorney-General and Colonial Secretary on the same day.
The table below is an incomplete listing of New Zealand politicians who have sat in Cabinet as Attorney-General since 1856. It does not show non-political attorneys-general. There were two previous Attorneys-General before responsible government was introduced in New Zealand in 1856: Francis Fisher who held office for less than one year in 1841, and William Swainson who held office until 7 May 1856. Peter Wilkinson was the half-brother of his successor, Jim McLay.
