The family came in search of a better life and a brighter future for the children and, the dad says, they found it.
For the past 15 years, New Zealand has been this family's home and he says they never felt like outsiders and were always made to feel like part of the community.
"My boy and girl are adults now but they grew up here, went to school here, they are Kiwis," he says, still shaken by the incident.
"This is so disappointing, we are so upset," he adds.
"We park in that spot all the time, this had never happened before."
Khorakchi does not know who left the note and suspects it is fueled by jealousy. "Some people are jealous. We work seven days a week," he told the Herald.
The restaurant owner says the family work hard at the business, all week, despite a problem with his right leg making it difficult for him to walk with ease.
"I work hard, I don't expect government help, we are all New Zealand citizens and we never did anything wrong to the country, which is why this is really upsetting."
Khorakchi shared the note on Instagram and was met by support from fellow social media users.
"I've known you over 10 years you are more Kiwi than most," someone commented.
"We are all human beings," someone else said.
