The long-term CIO of the Northern Territory Health Department Stephen Moo has resigned, with the NT News reporting that a referral has been made to the NT Police Special References Unit from the Department of Health.

Mr Moo has not been charged. An email sent by the NT's Department of Corporate and Information Services said he had resigned with effect from last Monday, September 18, and his position will be filled temporarily by NT Health finance head Ian Pollock while a recruitment process takes place.
