An official yesterday declined to guarantee the target of 141,000 new public rental homes by 2001 would be met. Deputy Secretary for Housing Andrew Wells said the Government had approved enough land for the Housing Authority to build the flats. Selina Chow Liang Shuk-yee of the Liberal Party asked: 'Can you 100 per cent guarantee that all 141,000 flats can be completed on time as the Government keeps saying you are confident of meeting the goal.' Mr Wells said the Government would closely monitor the progress of the housing projects, but said it was impossible to make a promise. The Government estimates the territory will need at least 390,000 flats between 2001 and 2006. Government Town Planner of the Planning Department Lau Sit-ming said it was studying whether more flats could be built at the Kai Tak airport site, North Lantau and Junk Bay.
