During the reign of a male
sovereign, appointees are called King's Counsel, and this applied from 1907 to 1952 during the reign of
Edward VII (1907–1910),
George V (1910–1936),
Edward VIII (1936), and
George VI (1936–1952). During
Elizabeth II's reign (February 1952 – September 2022), new appointees were called Queen's Counsel. King's Counsel who were living when Elizabeth II became the monarch became Queen's Counsel. Forty-three King's Counsel had been appointed before 1952. When King
Charles III ascended the throne on 9 September 2022 (New Zealand time), living Queen's Counsel automatically became King's Counsel. In 2008, the Lawyers and Conveyancers Act (Lawyers: Senior Counsel and Queen's Counsel) Regulations 2008 were promulgated which provided for the appointment of Senior Counsel instead of Queen's Counsel from 2008 onwards, although existing Queen's Counsel retained the former designation. There was only one round of lawyers appointed as Senior Counsel, in 2008. The rank of Senior Counsel was open to lawyers practising in firms as well as at the Bar. The regulations were revoked and replaced from 1 February 2013 by the Lawyers and Conveyancers Act (Lawyers: Queen’s Counsel) Regulations 2012, which provided for reinstatement of the rank of Queen's Counsel and restriction to those practising at the independent bar. Those who had been appointed Senior Counsel were offered redesignation as Queen's Counsel, and all elected to do so. Those who had been appointed as Senior Counsel while practising in firms were permitted to continue to practise in firms without losing the rank. There were no appointments between 2009 and 2011, and the only apponintments in 2012 were those of the Attorney-General, Chris Finlayson, and the Solicitor-General, Mike Heron. 26 lawyers were appointed to the rank in the 2013 appointment round, which was (and remains) the largest number. ==Overview of office holders==
