Social Workers compulsory registration

Parliament's Social Services select committee, is set to start hearings into whether there should be mandatory registration of social workers this week. Nearly 6000 social workers are voluntarily registered with the Social Workers Registration Board, but as many as 18,000 people identified themselves as social workers in the last census. Kathryn Ryan talks to Massey University's Kieran O'Donoghue, who says an overhaul of the system is long overdue.
