New Zealand has a very stable political environment. Elections are held every 3 years. Most of the 120 members of parliament represent a particular geographical area (their electorate) and have a lot of personal contact with people in that area. Some MPs represent only a particular party, to ensure that their party has the same weightage in parliament as it received at voting time. There is no "Upper House" in parliament.

Parliament buildings, especially the "Beehive" a round building that contains offices of the party in power, are a Wellington landmark. Members of the public may walk in the grounds and tour the buildings. There is a public viewing gallery and the debates are also broadcasted on the radio.

New Zealand does not have a written constitution, but functions on traditions inherited from Britain. Power is distributed between the legislature (parliament), the judiciary (courts) and the executive (government departments, local bodies and the ruling party) so that no branch of government monopolises. A Governor-General represents the Queen. The Treaty of Waitangi, an agreement signed by representatives of Maori tribes and the British Crown in 1840, is regarded by many people as a founding document for modern New Zealand society.

New Zealand police have an impeccable reputation. They do not carry guns. The police are also responsible for traffic control and giving drivers alcohol test. You have the right to a professional interpreter if you have to go to court or are questioned by the police.
