A senior union watchdog official has admitted an investigation into the Australian Workers Union could have been politically damaging to federal Labor leader Bill Shorten.

But Chris Enright, the executive director of the Registered Organisations Commission, says his decision to immediately start looking into allegations of wrongdoing by Mr Shorten's former union, the AWU, was "business as usual".

He's the latest in a string of witnesses summoned to appear in the Federal Court over claims by the union that a ROC investigation into union donations in 2005 and 2006 was part of a politically motivated witch hunt against Mr Shorten.
