New Zealand Connections, which helps to match Hong Kong students with New Zealand high schools, began 23 years ago with a Hong Kong mother's decision to send her twin sons to study at King's High School, in Dunedin.
The boys impressed their teachers with their attitude to school work, and this prompted the school to ask their mother, Linda Chen, to become a parents' representative in Hong Kong.
Ms Cheng has visited more than 100 Hong Kong schools to raise awareness of New Zealand as a place to study. She speaks to families that once thought mainly of the United States, Britain and Canada as study destinations for their children.
The company's manager, Olivia Wong Po-yie, says New Zealand has gained a reputation as an excellent place to study.
'Hong Kong students have been able to get visas for a long time, but in 1998 the New Zealand government became very active in promoting education when it decided to open the market for students from the mainland,' she says.
Ms Wong says most of the students her company helps to send to New Zealand schools are of Form Four level, about 15 to 16 years old, although some Hong Kong parents send children as young as 10 or 11 to boarding schools, such as St Peter's School in Cambridge, North Island.
