A former Ministry of Defence official, Sir John became the NAO's Comptroller and Auditor General in 1988.
Last March, he was appointed to advise ministers on issues relating to whether their private interests created a conflict with their ministerial duties under the ministerial code of conduct.
He was also given the authority, if necessary, to conduct inquiries to establish the facts behind any allegation of a breach of the code.
An NAO spokesman said: "The travel undertaken by Sir John is always on official National Audit Office business and is part of our international work to raise global standards of accountability."
He said Sir John had never extended the trips for personal purposes. He added that the NAO's work brought in £4 million a year for the Treasury.
