A review following shock allegations that outreach workers from North Richmond Community Health were dealing heroin has identified shortcomings in the centre's governance but stopped short of recommending drug users not be employed.

Outreach workers Matthew Honey, 49, and a 36-year-old woman from Brunswick West were arrested in October during a drug raid near the centre, which is the home of the controversial safe injecting room.

Mr Honey from North Richmond, who was on a course of methadone, was charged with trafficking heroin and will return to court next February. The other outreach worker was released and police said at the time she was expected to be charged on summons.

The state government launched an immediate independent review following the “extremely serious allegations” to find out whether the centre failed to prevent alleged criminal activity by its staff.
