It was the ambassador's first time in the Far North and came at the invitation of the Kaitaia Dalmatian Cultural Club.
"I was very surprised to see so many people of Dalmatian descent here. They came more than 150 years ago to some very harsh conditions, but they were embraced by the Maori people because they shared the same values," Dr Kusen said.
"They were about hard work and family and helping each other out and they shared the harsh conditions with the people here. And that's why they were so easily accepted. I am surprised and very proud at the recognition given to the contribution of Croatian and Dalmatian people to the area."
He was impressed by his tour around Gumdiggers Park, which has original gumdigger huts and a store, equipment, including an early petrol-powered chainsaw, a small mill and many other items.
"It's amazing to see the conditions they lived and worked in. But I'm also proud to see the innovation they used here," Dr Kusen said.
He was amazed when he saw an old black and white photograph on the park's wall of a group of gumdiggers standing in front of a kauri log that was six to seven metres in diameter.
"Wow, how did they even get a saw big enough to cut that down. It's such a huge tree and bigger than anything you would see in Europe," Dr Kusen said.
