Sir Edmund Percival Hillary was a New Zealand mountaineer, explorer, and philanthropist. On 29 May 1953, Hillary and Sherpa mountaineer Tenzing Norgay became the first climbers confirmed to have reached the summit of Mount Everest. They were part of the ninth British expedition to Everest, led by John Hunt. From 1985 to 1988 he served as New Zealand's High Commissioner to India and Bangladesh and concurrently as Ambassador to Nepal.

The Order of New Zealand is the highest honour in the New Zealand royal honours system, created "to recognise outstanding service to the Crown and people of New Zealand in a civil or military capacity". It was instituted by royal warrant on 6 February 1987. The order is modelled on the British Order of Merit and the Order of the Companions of Honour.
