The number of security incidents at Work and Income offices in the Bay of Plenty requiring police intervention has more than tripled in the past three years with three critical incidents among them.
Information obtained through under the Official information Act by the Bay of Plenty Times from the Ministry of Social Development showed since 2012 there had been three critical incidents, 39 serious incidents, 509 moderate incidents and 78 minor incidents.
Of the 629 reported incidents in the Bay of Plenty sites 12 required police intervention in 2012, 15 in 2013 and 41 in 2014.
A critical incident was the most severe and included death, serious injury requiring hospitalisation, bomb threats and arson.
The Ministry introduced a zero-tolerance policy to threatening behaviour in September after Work and Income staff members Peggy Noble and Leigh Cleveland were killed in a mid-morning shooting at their Ashburton office. A third person, Lindy Curtis, was injured.
