Sir John Mace

John Airth Mace was born in Ashburton, New Zealand, on 29 June 1932. He grew up in the South Island and received his secondary education at Ashburton High School and Nelson College. Those schools, and a New Zealand government cadetship to the Royal Military College, Duntroon, in Canberra beginning in 1950, set the path for a 41-year career in the New Zealand Army. He was commissioned into the Royal New Zealand Infantry Regiment on graduation from Duntroon in December 1953.

Mace's formal military education ran from Ashburton High School and Nelson College through RMC Duntroon (1950-1953). Later staff and joint courses matched his rising rank: Staff College, Camberley, in the United Kingdom (completed before his 1965 return to NZSAS command); the Australian Joint Services Staff College in Canberra in 1974; and the Royal College of Defence Studies in London in 1981. Those courses prepared him for service as Deputy Chief of Defence Staff, Chief of the General Staff, and Chief of Defence Staff.

Operational service defined Mace's early career. He served with the original New Zealand Special Air Service Squadron in the Malayan Emergency (1955-1957) and was Mentioned in Despatches. He commanded the NZSAS Squadron from 1960 to 1962 and again in 1965, a period later described by historian Ron Crosby and by veterans as essential to the unit's reformation. In 1966 he was a company commander with 1RNZIR in Borneo during Confrontation. In 1967 he led Victor Company, 1RNZIR, on its Vietnam deployment and received the MBE in 1968.

Staff and command posts then carried him to the top of the force: Director of Infantry and SAS (1969-1970); CO 1RNZIR in Singapore (1971-1973); OBE (1974); Commander New Zealand Force South East Asia (1979-1980); Deputy Chief of Defence Staff (1981-1984); Chief of the General Staff (12 December 1984 to 30 November 1987); and Chief of Defence Staff (1987-1991). He was appointed CB in 1986 and KBE in 1990, retiring in 1991 after four decades in uniform.

Mace married Margaret; at his death in 2026 they had been married for 65 years. He was the father of Angus and Sarah, father-in-law of Bill Loutit, and grandfather of Sam (London), John (Wellington), Ben (Perth), Jack (Kentucky), Poppy (Sydney) and Lily (Auckland), as named in the family death notice published in The New Zealand Herald. Soldiers who served under him described a private man, outwardly stern and demanding, who remained intensely loyal to the people under his command long after retirement. He lived his later years in New Zealand and died in Auckland.

Public interviews and obituaries present Mace less as a theorist than as a practitioner of soldier-centred command. At the funeral of fellow Original Lindsay "Lofty" Williams in 2008 he said Williams "firmly believed the strength of the Army lay within its soldiers," a conviction colleagues applied to Mace himself. Major (retired) John "Jack" Hayes remembered a commander who pushed for greater achievement while showing deep compassion when soldiers and families suffered. Into old age Mace continued to press for appropriate recognition of the NZSAS Originals, treating institutional memory as a duty rather than nostalgia.

Mace's lasting mark sits at two levels. As an Original and later squadron commander he helped rebuild the NZSAS after its first Malayan tour, setting standards that later officers, including Hayes and those who served in Vietnam under the troop-to-Australian-squadron model, inherited. As Chief of the General Staff and Chief of Defence Staff he led the New Zealand Army and then the whole Defence Force through the late Cold War years into 1991. After retirement he served as Honorary Colonel of 1RNZIR (from 2006), presented medals at Linton, spoke for fallen comrades, and stood with families when Te Auraki brought home those buried overseas. Air Marshal Tony Davies's farewell tribute framed that arc as professionalism and dedication across a lifetime.

Mentioned in Despatches for Malayan Emergency service (London Gazette, 23 May 1958); Member of the Order of the British Empire for distinguished service in Vietnam (1968); Officer of the Order of the British Empire (1974 New Year Honours); Companion of the Order of the Bath (1986 New Year Honours); Knight Commander of the Order of the British Empire (1990 Queen's Birthday Honours). Senior appointments included Chief of the General Staff (1984-1987) and Chief of Defence Staff (1987-1991). He later served as Honorary Colonel of 1RNZIR.

Mace appears in official biographies of New Zealand's Vietnam and SAS generations, including the Victor Company veterans' site and the New Zealand history record of Vietnam honours. Historian and lawyer Ron Crosby treated his NZSAS command years in NZSAS: The First Fifty Years. The New Zealand Herald's David Fisher obituary of 25 September 2026 was the principal public farewell, drawing on serving and retired soldiers. Documentary film about the NZSAS, notably the First Among Equals series, covers the unit Mace helped form and later commanded, though it is not a personal biography.

Sir John Mace died in Auckland on 22 September 2026, aged 94. The cause of death was not made public. The New Zealand Herald published David Fisher's obituary on 25 September 2026. The family death notice named Margaret, Angus, Sarah, Bill Loutit and six grandchildren, and announced a service at St Mary's-in-Holy-Trinity Cathedral, 446 Parnell Road, Parnell, on Wednesday 30 September 2026 at 1pm, with a full military funeral. Chief of Defence Force Air Marshal Tony Davies issued condolences on behalf of the Defence Force.
