Mr Pearce said: "The base chapel is a beautiful, peaceful space, very much a shrine to the airforce.
"For Dave and I to celebrate our marriage there, amongst friends, family and fellow servicemen and women, was particularly poignant."
Defence Force principal chaplain Colonel Lance Lukin gave a reading and offered prayers at the service.
Celebrations continued well into the night, Overwatch said.
Celebrant Richard Tankersley, who officiated at the ceremony, described the couple's marriage on Facebook as "a really big step for two great guys and another small step in the ongoing realisation of equal rights for all New Zealanders".
The Herald last night contacted Mr Pearce, who referred comment to the Defence Force communications sector, which could not be reached.
