Candy Yan, president of the Bay of Plenty Chinese Business and Commerce Association, said in the past six to 10 months she had noticed exceptional growth.
Ms Yan said in the first four of the past five years she knew or recognised 90 per cent of the local Chinese population, and spotted a new face maybe once a month. "But now it's every day," she said.
"In about the last six months we have a new commercial Chinese-speaking real estate agent, we have three residential agents speaking Chinese and four or five Chinese accountants and a Chinese-speaking lawyer."
In the Western Bay, the growth also came mostly from the Indian population, which increased by more than 1100 between 2001 and 2013 - an increase of nearly five times.
This has been reflected in the establishment of two Sikh gurudwara (temples) in the area. There are only 13 nationwide.
The report, Beyond the metropoles: The Asian presence in small city New Zealand, shows about 20 per cent of Indians in Tauranga and the Western Bay were studying and about 75 per cent were in the labour force.
Figures from Statistics New Zealand show 4693 migrants settled in the Bay in the year ending July, up 18.1 per cent on the previous year.
