But goods handled by river trade terminal and mid-stream dropped 4.7 percent to 641,000 TEUs in January, the data showed.
Analysts said port operators at Kwai Chung lowered prices late last year to attract business, so some customers turned from river trade and mid-steam to the more effective facilities at Kwai Chung.
Hong Kong port operators would not disclose the price levels.
In recent years, Hong Kong has continued to lose market share to the neighbouring Chinese city of Shenzhen, where exporters can ship their goods at prices of about one-third less than they are charged in Hong Kong.
Hong Kong could lose its title as world's busiest container port to Singapore this year. Hong Kong moved 22 million 20-foot equivalent units of goods last year, up 7.7 percent, but Singapore handled 21.3 million TEUs, up 16 percent.
