Police officers in Palmerston North will be using their iPhones to record video statements from victims at the scene of some family violence incidents.
The four-month pilot programme is being welcomed by Justice Minister Amy Adams and Police Minister Michael Woodhouse.
"It will never be easy for a victim of family violence to face their abuser or to have to repeat their experience, so it's important we find ways to provide additional support to victims during this difficult process," Ms Adams said.
Mr Woodhouse said the video statements will be actively used to help investigate and prosecute family violence incidents.
"The benefits of good quality video statements include less likelihood of recanted statements, earlier guilty pleas and reduced court time," he said.
The pilot will be evaluated before any decisions are made about a wider rollout.
