Most of the 744 medals stolen by a Wairouru Museum employee have been reclaimed by the museum.
Former National Army Museum registrar Keith Davies was found with the valuable medal haul in his North Queensland home late last year following a ONE News investigation.
Museum board member Colonel David Moloney said they had received a great response from unknowing collectors from around the world who had purchased the stolen medals.
"We've still got 57 groups outstanding, which is a total of 130 medals, and we're gradually getting there," said Moloney.
"The people are owning up all around the place, all around the world, and telling us they have them and are returning them."
Davies, 57, is serving a three year jail term after pleading guilty to stealing the antiques haul in October last year.
He stole the medals, believed to be valued at more than $233,155, between 1995 and 2002.
A World War II German soldier's pack and a helmet plate, a military statuette and 100 military histories valued at $25,700 are among the items taken.
Davies is believed to have left the museum with the medals concealed, walking out without anyone knowing or stopping him.
Davies served as a territorial soldier in Canterbury and Wellington between 1977 and 2003, and as part of a peace monitoring group in Bougainville in 2000.
