Police have completed rolling out iPhones and iPads to frontline staff in the Wellington district.
More than 6000 police officers will receive iPhones and 3900 of them iPads in a phased national rollout over the next two months.
Last month more than 400 "champions" across all police districts received their devices.
"We have carefully planned for the increase in scaling, based on the forecast number of mobile device users, and have increased our infrastructure to deal with this," says inspector Simon Feltham, mobility workstream lead. "We are closely monitoring this activity as the rollout progresses."
The cost of the rollout is $4.3 million. Over the next decade, police will spend $159 million in operating expenditure to fund the initiative.
Productivity benefits of $305 million are projected. Vodafone is providing the mobile connections.
