The pair were formally announced at a function in Auckland last night.
The event also marked one month to the Olympic Games, which will run from July 23 to August 8 in Tokyo.
It will be the first opportunity for male and female athletes to jointly carry their national flags at a Games opening ceremony, following a change in Olympic rules.
Bond said he would be extremely proud to carry the flag alongside Hirini.
“If you look back on the people who have been our flag-bearers over the years, it’s a pretty amazing bunch of athletes, so to be bestowed this opportunity is really special to me,” he said.
Peter Snell was team flag-bearer the last time New Zealand competed at an Olympic Games in Tokyo, in 1964.
