"I am sure over the years various Holocaust items have been locked away gathering dust, things that we would like to bring to people's attention in the new national Holocaust centre."
Masterton man John Schnellenberg came to New Zealand as a refugee in 1939 and has contributed to research gathered by the Holocaust Centre.
"The purpose behind this is that today's citizens, more than half of whom were not born when this happened, have got somewhere local to learn about what did go on."
Mr Schnellenberg lost grandparents, aunts, uncles, and cousins to the concentration camps of Nazi Germany. He and his parents were among the lucky few.
Mr Schnellenberg, who was aged three at the time, said his father was warned to leave Berlin and applied for Canadian visas for the family.
"But we saw a photo of the Botanical Gardens in Wellington in the local paper, and said scratch that, we said New Zealand."
The Holocaust Centre opens to the public on April 23.
