"Several roads have been closed in order to make way for hawkers in conjunction with the Chinese New Year celebration," he said. The roads had been closed since 1pm on Wednesday until 2am on Thursday.
Roads closed for the night market were Jalan Tun Fuad Stephens, Segama and along Le Meridien Hotel to the roundabout nearby Hyatt Regency Kinabalu.
Earlier, he urged all hawkers and visitors not to litter but throw their rubbish into the dustbins.
"It is to ensure cleanliness of our city in relation to Visit Malaysia Year," he said.
"I also hope that the public will be more extra careful when shopping to avoid pickpockets," he said.
