He settled in Nelson, New Zealand in 1842, and became the first recorded Chinese migrant to that country.

Large groups of Chinese from southernGuangdongprovince followed in the 1860s, prompted by a gold rush in the Otago region.

Some Chinese tycoons were nurturing when it came to Chinese migrants. For instance, Choie Sew Hoy in Dunedin, a principal city in Otago, first offered immigration information and sold instruments to gold miners, and gradually established a business empire.

His family, now in its sixth generation in New Zealand, still plays an important role today.
