A man who had dozens of bonsai stolen from his Mt Albert back garden said his biggest fear was that his precious trees would be destroyed or not cared for.
The man's son Nick Yu said his father had tended the trees for four or five hours a day for decades and considered them his babies.
"He was heartbroken at the theft but he is a resilient man and he said well, it shows someone really likes my trees," Yu said.
"What my father really wants is for the trees to be looked after and loved. His biggest fear is that someone will panic and destroy them."
Yu, who works as a dentist in Melbourne, said when he was a child in Taiwan his father would take the family for walks pointing out different trees and rock formations.
"My father believes bonsai need to be enjoyed by everyone and he used to have them out the front so the neighbours and passersby could see them,'' Yu said.
"People always commented and my father really loved that others could enjoy them."
After they were stolen the man reluctantly moved his collection to the back garden and installed a lockable gate.
During lockdown the man spent more time tending the bonsai and his wife had time to take photos of the collection.
"Up until then there were no photos of them," Yu said.
"My mother was admiring the collection and decided to take some photos during lockdown so if he doesn't get them back at least he has something of them."
Police were investigating and said the bonsai theft could be compared to stealing fine art.
"This should be compared to the loss of irreplaceable art and involves a man's life-long commitment to their care," Acting Detective Sergeant Thomas Malcolm said.
