Police officers suffered more than 1650 injuries in the past year at a cost of over $2 million.
New Zealand First obtained the information under the Official Information Act and says every front-line police officer should be issued with a Taser.
Police officers suffered from 1,656 injuries while on duty in 2013/14 at a cost of $2.1 million.
Costs of injuries include income compensation, medical treatment and other costs associated with rehabilitation and return to work.
"There's an element in society who view the Police as sport and when it comes to pursuits, know they can get away with it," said Ron Mark, NZ First's spokesman on police.
