A government-led task force will be asking residents forced to flee their Wang Fuk Court homes by last month's inferno for their views on rehousing arrangements, Chief Executive John Lee said.

He also said on Friday that the task force, led by Deputy Financial Secretary Michael Wong, had to be tread with care in reaching out to those affected, some 4,000 of whom had been relocated to temporary housing for the time being.

"It will be up to them to tell us what they want, even though there may be different wants and different needs. But at the same time, they are still undergoing a difficult period of big transition," Lee said.

"While I ask the task force to collect views, I think they have to do it in a very tactful manner. We don't want to upset the families while they are at this difficult time. So there may be a process for the task force to go through."

Lee also said he would "certainly" report on post-disaster efforts in his annual duty visit to Beijing, during which he's expected to brief President Xi Jinping and other mainland officials on the latest developments.

The president attaches great importance to the handling of the tragedy, the CE added, and has issued instructions calling for rescue efforts from local authorities.

The chief executive's duty visit to the capital is usually scheduled for December, and Lee said he "believes the arrangement this time around would be the same as previous years".
