Police believe the war-medal thieves used night-vision equipment and walkie-talkies during the break-in at Waiouru Army Museum.
Officers raided addresses linked to the two key suspects last week, with a search warrant allowing the seizure of shoes to match against footprints found at the scene of the December 2 break-in.
The warrant, seen by the Herald, shows police were also looking for specialised burglary gear such as night-vision equipment as varied as "camcorders, torches, lights and marking devices or material".
The communication devices sought included walkie-talkies and cellphones but also any electronic equipment "capable of storing plans, photographs or notes".
The tools sought included a screwdriver "capable of removing round-headed wooden screws".
