Members of the Defence Force will march in uniform in the Auckland Pride Parade next month.
The Defence Force's Overwatch group - a peer support network for gay, lesbian, bisexual and transgender members - has signed up for the parade.
Event organiser Jonathan Smith said: "I'm sure they're going to be the crowd favourite."
Smith said participation from the Overwatch group is a milestone for acceptance of sexual orientation.
"I can't say we're the first pride parade in the world to have a defence force marching, but we're definitely one of the very few where they're actually permitted to march in uniform."
