Dignitary Protection Service

The Dignitary Protection Service (DPS), previously the Diplomatic Protection Service, is a branch of the New Zealand Police that provides personal security for both national and visiting diplomats and VIPs. National VIPs that receive constant protection are the prime minister and the governor-general, while ministers, members of Parliament, the judiciary and the leader of the Opposition receive protection as needed.
