Ropitini, who returned to Napier about four years ago and soon set a goal of finding a stronger presence for Māori - both people and culture - in the globally-renowned Art Deco image of the city, concedes he hadn't thought about the significance of the Sunken Garden. The garden, meanwhile, was excavated more than 50 years ago and officially opened in 1967.
He wasn't the only one, for even city promotional material described it as a "hidden treasure," but as highlighted by the newfound gardener-cum-cultural adviser it had a "very Māori" appeal, and was common place for spiritual, therapeutic and healing visits.
"I've seen it," said Pronesti. "A lot of people come and sit here, just thinking."
"Just listening to Antonio changed the whole way I looked at the Sunken Garden," said Ropitini. "It wasn't till Antonio woke my Māori brain... I no longer saw a European garden, but a garden with a lot of Māori potential."
For Pronesti, there's a personal touch, enhancing the connection, coming to Napier initially to follow a girl and falling in love with Napier as well, to the extent of an affinity fused with the mix of what he says are some similarities between Māori culture and his own heritage in Italy.
"Whenever I go back to Melbourne and come back, I come through the airport I feel like I'm coming home," he said. "So this is home."
Ropitini, roping in help from such people as creative presentations guru Te Rangi Huata, is now working on the Art Deco Festival's Toi Deco Māori, creating a village offering cultural events and showcasing traditional Māori arts and story-telling, with walks in the vicinity.
Pronesti foresees widespread popular appeal, not only during the festival but also particularly as cruise liners start returning to Napier. "They would flock to it," he said.
"It is, said Ropitini, "an ongoing work in progress."
