## Oldest living prime ministers of New Zealand

Not all prime ministers live to become the oldest of their time. Of the 33 deceased prime ministers, 16 eventually became the oldest of their time, while 17 did not (including all 5 prime ministers who died in office, and 12 others). Jim Bolger has held this distinction since Bill Rowling's death on 31 October 1995 a record 28 years, 342 days so far. He surpassed the previous record held by Robert Stout on 24 November 2018. Robert Stout became the oldest living prime minister when John Hall died in 1907 and remained so until his death in 1930, for 23 years and 24 days.
John Hall became the oldest living prime minister after the death of George Waterhouse, but he survived Waterhouse by only 323 days. On one occasion the oldest living prime minister lost this distinction not by his death, but due to the appointment of a prime minister who was older. Sidney Holland ceased to be the oldest living prime minister when Walter Nash was appointed.
John Hall was the oldest to acquire this distinction at the age of 81 years, and 231 days. Francis Bell, who was 84 years, and 348 days old when he died, was the oldest prime minister to die without ever acquiring this distinction. Mike Moore, who died on 2 February 2020 at 71 years, and 5 days old is the most recent prime minister to die without ever acquiring this distinction.
