Question: M. P. Shiel and Anna Quindlen, are of British nationality?
Context: New Zealand nationality law (Raraunga Aotearoa in Māori) determines who is and who is not a New Zealand citizen.  The status of New Zealand citizenship was created on 1 January 1949 by the "British Nationality and New Zealand Citizenship Act 1948".  Prior to this date, New Zealanders were only British subjects and New Zealand had the same nationality legislation as the United Kingdom and other Commonwealth countries (see also British nationality law). Matthew Phipps Shiell (21 July 1865 – 17 February 1947) – known as M. P. Shiel – was a prolific British writer of West Indian descent.  His legal surname remained "Shiell" though he adopted the shorter version as a "de facto" pen name. British passports are passports issued by the United Kingdom to those holding any form of British nationality.  There are different types of British nationality, and different types of British passports as a result.  A British passport enables the bearer to travel worldwide and serves as proof of citizenship.  It also facilitates access to consular assistance from British embassies around the world, or if also a citizen of the European Union, any embassy of another European Union member state.  Passports are issued using royal prerogative, which are exercised by Her Majesty's Government. The status of British Overseas Territories citizen (BOTC) relates to persons holding British nationality by virtue of a connection with a British Overseas Territory (BOT).  Nearly all BOTCs are also British citizens as a result of the changes made to British nationality law in 2002. British National (Overseas), commonly known as BN(O), is one of the major classes of British nationality under British nationality law.  Holders of this nationality are British nationals and Commonwealth citizens, but not British citizens.  The nationality itself does not grant right of abode anywhere in the world, including United Kingdom or Hong Kong, but most BN(O)s possess either right of abode or right to land in Hong Kong.  BN(O)s are subject to British immigration controls and do not have the automatic right to live or work in the United Kingdom. The British Nationality (Hong Kong) Selection Scheme, usually known in Hong Kong as simply the British Nationality Selection Scheme (BNSS), was a process whereby the Governor of Hong Kong, by Order of Queen Elizabeth II of the United Kingdom in the British Privy Council, invited certain classes of people, who were permanent residents of Hong Kong with the right of abode, under the Hong Kong Immigration Ordinance, "Chapter 115" "", and who were also considered British nationals under Parts II, III and IV and Part V, Section 38, of the British Nationality Act 1981, "Chapter 61", but were not British citizens (with the right of abode in the United Kingdom) under Part I, Sections 1 and 2, of the 1981 Act, to apply to be considered and then be selected to become registered as British citizens under the British Nationality (Hong Kong) Act 1990, "Chapter 34", by the British Home Secretary, under the advice and the recommendation of the Governor with the consent of the British Foreign Secretary. A British protected person (BPP) is a member of a class of certain persons under the British Nationality Act 1981 associated with former protected states, protectorates, mandated and trust territories under British control.  The inhabitants of these former states or territories were never automatically entitled because of their birthplace to become British subjects or citizens, but were given the status of British protected person instead.  (A few of those born in such areas might have other claims to British nationality; for example, one based on the status of their parents.) One True Thing is a 1998 American drama film directed by Carl Franklin.  It tells the story of a woman who is forced to put her life on hold in order to care for her mother who is dying of cancer.  It was adapted by Karen Croner from the novel by Anna Quindlen.  The novel and film are based on Anna Quindlen's real life and her struggle of dealing with the death of her mother, Prudence Pantano Quindlen in 1972, due to ovarian cancer. British Overseas citizenship is a form of British nationality under the British Nationality Act 1983.  BOCs are British nationals but do not have the right of abode in the United Kingdom.  This citizenship is normally for certain people who retained British nationality after independence (e.g. Kenya), but do not have enough ties with the United Kingdom. Anna Marie Quindlen (born July 8, 1952) is an American author, journalist, and opinion columnist.
