CORRECTED - (OFFICIAL)-ECB covered bond plan sufficient for now - Nowotny

(Corrects references to allocation of spending after Austrian central bank says ECB bond buying will be based mainly on capital key, but not entirely)

VIENNA, July 6 (Reuters) - The European Central Bank's 60 billion euro program to buy covered bonds is sufficient for now, Governing Council member Ewald Nowotny said on Monday.

Nowotny added that the bank would review the state of credit market later in the year before deciding whether or not more stimulus was needed.

The Austrian central bank said later that the covered bond buying would be based mainly on the percentage of Eurosystem capital each country holds -- known as the capital key -- although not entirely.

Asked if the bank was planning to buy up other assets, Nowotny said: "No, for the time being we have the covered bond programme, and I think that is a significant additional non-conventional measure."

"I think that the programme has to run its course and then analyse," he told reporters.
