THE Government is set to revamp the Housing Authority following months of bickering between the body and grassroots groups over policies. Amid increasing calls for more grassroots representatives to be appointed to the statutory body when half of its 22 members reach the end of their two-year term on Wednesday, only four of them have had their reappointments confirmed by the Governor, Mr Chris Patten. Mr Nicholas Brooke, Ms Leung Wai-tung, the Reverend Sean Patrick Burke and tenants' representative Mr Hau Shui-pui received verbal notification from the authority on behalf of the Government last Friday. Of the remainder, surveyor Mr Leung Chun-ying is the only member who has been approached by the authority for a reappointment. Mr Leung, a Hongkong affairs adviser and a former secretary-general of the now defunct Basic Law Consultative Committee, said he needed time to consider. Having just set up his own surveying firm, he had reservations about the appointment, saying he needed to strike a balance between the time devoted to public service and his own business. ''I would hope to do well in my capacity, but when the atmosphere becomes too political it will no longer be a mere professional job and it will not be my game,'' he said. ''I will not be surprised if more members decide not to accept reappointment. If people demand to elect their own representatives on to the authority, I am willing to offer them my place,'' he said. Regional Councillor Mr Carlos Cheung Hon-kau, who was appointed in 1985 and is the second most senior serving authority member, and lawyer Mr Norman Leung Nai-ping announced that they would retire on completion of their service. Mr Norman Leung said he was quitting because the housing issue had become too political. ''The demonstrations and personal attacks were politically motivated, and the manners of protesters were bad,'' he said. The future for Wong Tai Sin District Board chairman Mr Chan Kam-man, Regional Councillor Mr Pao Ping-wing, tenants' representative Ms Ho On-nei and Housing Society executive director Mr Victor So Hing-wo remained in doubt. They were not in contact with the authority last Friday because they were in meetings or engaged in other business. Commenting on the lack of notice, Mr Pao said: ''The Government has its reasons for the delay, and will not be surprised to hear the termination of my service.'' Mr So was more optimistic, saying a delay did not necessarily mean he was to be dropped and he felt confident that his appointment would be renewed. Meanwhile, a World Bank property consultant said the composition of the Housing Authority should be more balanced. Mr Peter Fong Kwok-wing said if there were tenant representatives on the authority, those waiting in the queue to be resettled should also be given a say in formulating housing policies. But he said professionals in the construction field should be retained as they provided expertise and advice for the authority.
