Sydneysiders could soon duck into an inner-city wine bar for a glass of red after midnight or tuck into a late-night restaurant meal in the CBD under changes to the city's late-night planning rules.

City of Sydney councillors unanimously endorsed an overhaul of the plan that determines where and when night-time activity can take place throughout the inner city at a meeting on Monday night.

Lord Mayor Clover Moore flagged the potential reforms in November in response to feedback from residents, businesses and visitors who wanted to revive Sydney’s nightlife and economy.

Under the changes, shops, eateries and other unlicensed businesses in central Sydney - from Hyde Park to Darling Harbour, and south to Central station - will be allowed to trade 24 hours a day.
