Officers in all New Zealand prisons are to have access to pepper spray, Corrections Minister Anne Tolley has announced.
The decision follows a 12-month trial in 2011 which the Government said found pepper spray to be an effective tactical option and deterrent, reducing the risk of injury to both staff and prisoners in some potentially violent situations.
Officers will not routinely carry pepper spray on their belts, due to the risk of prisoners assaulting staff and stealing the spray, which could then be used against officers and other prisoners.
"The number of serious assaults on prison staff has fallen dramatically, down 75 per cent over the last fifteen years," Mrs Tolley said.
"However, we are continually looking at ways to improve safety for frontline staff, who have to deal with dangerous and violent individuals."
