Centrelink public servants who ask too many questions about their agency's controversial "robo-debt" recovery effort are being "managed" out of debt recovery units, according to independent MP Andrew Wilkie.

The Tasmanian independent also alleges public servants are being played against each other by managers, competing for the highest daily quota of debt notices.

But Centrelink is unhappy with Mr Wilkie's letter to Ombudsman Colin Neave, with the agency saying on Monday the the allegations are inaccurate or misleading.

Centrelink says there are no quotas and that Mr Wilkie's accusations about the management of mental health issues among clients were overblown.
