The new Medal Repository at the National Army Museum in Waiouru has opened Thursday with 10,000 war medals, all donated by the families of servicemen.
A number of medals were stolen from there in 2007.
The repository was opened by Defence Minister Dr Jonathan Coleman who said there have been other changes at the museum.
He said a database will now allow visitors with family connections to find the donated medal and information about their relative.
Today's opening is a tribute to one of the country's most decorated heroes, Reginald Judson, who was awarded the Victoria Cross, the Distinguished Conduct Medal and the Military Medal between July and August 1918.
