"Rollout of one cap to each constabulary member is expected to start in September and run through to March 2022," Assistant Commissioner Tusha Penny said this afternoon.
Staff feedback indicated the existing forage caps could be cumbersome and prone to being knocked off in dynamic situations, Penny added.
"These caps are a practical, comfortable alternative to the forage cap, which look completely in keeping with the operational uniform," Commissioner Andy Coster said.
"We have listened to our frontline staff who have been calling for an alternative for some time."
Some specialist cops, including the Commercial Vehicle Safety Team, already wear caps, as do police in Australia and some other Commonwealth jurisdictions.
The new cap will replace caps some specialist Kiwi police in maritime and canine units used.
