"But with fortitude, guts, sweat, tears and perseverance they were able to prosper for their children, grandchildren and great-grandchildren," Mr Yelavich said.
"We now feel and believe that this visually stunning memorial will be an enduring edifice to admire and that everyone can be justly proud of."
Mr Yelavich went on to describe the pou's features, beginning at the top with the Biokovo mountain range followed by a typical stone house, the Adriatic Sea, trading and fishing boats, a steeple and bell tower, a monk playing a gusla, a tamburica player and dancers.
Lower down a young man stands on a jetty, waiting for the ship that will take him to New Zealand, a koru representing the joining of his place of birth and his new home.
There are crude shanties, gum diggers, camp oven bread and a spit-roasted lamb, orchards, grapes and wine-making, fishing and farming.
Many young Croatian men took Maori wives, Mr Yelavich added, and from those marriages came fine, strong, able children who had excelled in every sphere, from business, the professions and trades to the arts and sport.
