Nominations for the Selection Committee will not be published, a senior Beijing official has said.
Nominees' names will be available for their own inspection only.
It is believed there could be more than 10,000 nominations by the September 14 deadline.
The official said the Preparatory Committee had not been authorised to publish the names.
'Who knows whether the nominees will be happy to see their names publicised? Some might not,' he said.
'The nominees will be allowed to check the list to see whether their nominations have been received.' A spokesman for the committee secretariat in Hong Kong was not sure whether the decision was final.
'We only published the names of the organisations which asked for application forms. Individuals have their privacy,' she said.
But she added they had not been asked by nominees to keep their identities confidential.
In a reference list on the form, it says the Preparatory Committee can publicise the names of the nominees, their relevant sectors and organisations 'when necessary'.
Selection Committee sub-group member Lee Kai-ming said: 'I don't think it will make people embarrassed.
'By publishing all the names, it will let the nominees know who their competitors are.' Another Preparatory Committee member, Lau Siu-kai, said publicising the list would enhance transparency.
