A group monitoring the use of tasers says new weapons being trialled by the police in Wellington need better safeguards.
The new X2 tasers can fire two shots without being reloaded and are paired with a high definition camera which can be mounted on the unit itself, or an officer's glasses.
Lawyer and Campaign Against Tasers spokesperson Marie Dyhrberg said the camera should automatically be turned on when the taser is readied to fire, with no way of turning it until the incident is over.
Ms Dyhrberg said filming may raise privacy issues, but it also means the taser use can be properly monitored.
If adopted after an evaluation lasting six months, the new model will replace the 900 tasers currently being used.
