NZ police will carry firearms on their persons in very specific circumstances, but it's not standard. There's also the "Armed Offenders Squad", maybe analogous to a SWAT team, who are armed. Don't know too much about them, you just hear them mentioned on the news when there's a gunman who has shot someone.
