A new step forward in policing has taken to Canterbury skies.
The Eagle helicopter is being trialled for five weeks during which time it'll target fleeing drivers, become a swifter response to call outs and be available for deployment around the South Island.
Police Minister Stuart Nash says it's 21st century policing.
"As our roads become more congested, as our bad guys become badder, as they use more powerful tools, we need to keep pace."
It's the first time one's been based in the South Island.
Police Commissioner Mike Bush told Chris Lynch the rising number of fatal police pursuits was one of the driving factors behind the trial.
"Your not going to get away; regardless of whether its minutes, hours or days, you will be held to account."
He says the success of the trial will be judged by a number of criteria.
"That's how much crime we actually prevent, how many incidents they respond to, how many people we support in the apprehension, but mostly how effective it is for our staff on the ground and the communities we're here to serve."
