The first early Chinese immigrants to New Zealand are Cantonese from Guangdong Province, and they went here for the Central Otago goldrush of 1861. The former Chinese gold-mining settlement near the present town of Lawrence is being restored as an open-air museum, as has a similar former settlement at Arrowtown. Because of this influx of Cantonese during the 1860s, there is a strong Chinese presence in Dunedin, which has the country's only traditional Chinese Garden. Recent mayor from 2004 to 2010, Peter Chin, is of Chinese descent. During the late 19th century and early 20th century, the area between Rattray Street and Stafford Street at the southern end of the city's CBD had the highest concentration of Chinese businesses in the country, notably Choie (Charles) Sew Hoy's importing company. A traditional Chinese garden is now a feature of the central city.
