Chief Executive John Lee on Tuesday said the authorities will continue to hold test events at the new Kai Tak Sports Park.

Speaking ahead of the weekly Executive Council meeting, Lee said officials will learn from the experience of the first test run at the park last Sunday.

He said a second test event will be held at the Youth Sports Ground in mid-November, with a trial planned in the main 50,000-seat stadium in January.

"The challenge of course is the dispersal of crowds after an event which will comprise of 50,000 spectators. That is a challenge we must take up boldly," he said.

"That is also why I have been demanding different levels of drills, so as to test different elements of operational procedures, different areas of risks, and also to learn about the experiences of those who may eventually become the final spectators of the 50,000 audience."

Lee added that the government will draw up various contingency plans, including on how to deal with unstable weather and emergencies.

The park is due to officially open in the first quarter of next year.
