A former Customs lawyer claim that he was told to bury bad news matches similar stories which have sparked a wide-ranging inquiry by Chief Ombudsman Dame Beverley Wakem.
She said she was "appalled" by Curtis Gregorash's claim. "Having said that one of the reasons I am undertaking of selected agencies in respect of their OIA practices is that anecdotally a number of people have told me similar stories," she said.
She said a planned inquiry to be launched after the election could see the Ombudsman's office using its Commission of Inquiry powers to compel evidence to be given under oath were there signs information was being hidden.
"Ministerial offices will be figuring in our inquiry and that is all I will say."
She said the Ombudsman's relationship with the government service was based on trust. Without that, she said, "we're all in trouble".
