The files, dating from 1954 to 2009, include drawings of flying saucers and alleged samples of alien writing.
The files include details of New Zealand's most famous UFO sighting when strange lights were filmed off the South Island town of Kaikoura in 1978.
An official report from the time said natural phenomenon could explain it.
