"God Save the King" or "God Save the Queen" (depending on the reigning monarch) is the national and/or royal anthem of the United Kingdom, most of the Commonwealth realms, their territories, and the British Crown Dependencies. The author of the tune is unknown and it may originate in plainchant, but an attribution to the composer John Bull is sometimes made.

"God Save the King" is the de facto national anthem of the United Kingdom and one of two national anthems used by New Zealand since 1977, as well as for several of the UK's territories that have their own additional local anthem. It is also the royal anthemplayed specifically in the presence of the monarchof the aforementioned countries, in addition to Australia (since 1984), Canada (since 1980), Belize (since 1981), Antigua and Barbuda (since 1981), The Bahamas (since 1973), and most other Commonwealth realms.

In countries not part of the British Empire, the tune of "God Save the King" has provided the basis for various patriotic songs, though still generally connected with royal ceremony. The melody continues to be used for the national anthem of Liechtenstein, "Oben am jungen Rhein", and the royal anthem of Norway, "Kongesangen". The melody is used for the American patriotic song "My Country, 'Tis of Thee" (also known as "America"). The melody was also used for the national anthem "Heil dir im Siegerkranz" of the German Empire from 1871 to 1918 and as "The Prayer of Russians", the imperial anthem of Russia from 1816 to 1833. In Switzerland, it is known as "Rufst du, mein Vaterland".

Beyond its first verse, which is consistent, "God Save the King" has many historic and extant versions. Since its first publication, different verses have been added and taken away and, even today, different publications include various selections of verses in various orders. In general, only one verse is sung. Sometimes two verses are sung and, on certain occasions, three.The entire composition is the musical salute for the monarch and royal consort, while other members of the royal family who are entitled to royal salute (such as the Prince of Wales, along with his spouse) receive just the first six bars. The first six bars also form all or part of the viceregal salute in some Commonwealth realms other than the UK (e.g., in Canada, governors general and lieutenant governors at official events are saluted with the first six bars of "God Save the King" followed by the first four and last four bars of "O Canada"), as well as the salute given to governors of British overseas territories.

The Minister of Internal Affairs is a ministerial portfolio in the government of New Zealand with responsibility over the Department of Internal Affairs. The position of Minister of Internal Affairs has existed since the Department of Internal Affairs replaced the Colonial Secretary's office from 19 November 1907. The responsibilities of the office have been progressively reduced as other ministerial roles have been spun-off from the Department of Internal Affairs. Today his or her remit includes internal security and administering applications for citizenship.
