Auditors, however, did find some problems in the implementation of post-quake rebuilding plans, distribution of relief funds and management of reconstruction projects, said the NAO.
The NAO has transfered one violation case to the procuratorial organ in 2009. Two people responsible for the violation were arrested and another 11 people were in custody.
The NAO said it and its local offices have already released the auditing results to the public.
Liu Jiayi, chief auditor of the NAO said earlier that they would, in 2010, continue to keep a close eye on the whole process of post-quake rebuilding.
