How Parliament makes a law

Three branches of government, where ordinary people get a say, and how Treaty settlements become law.

Power in New Zealand is shared so no single person or group holds all of it. This is called the separation of powers.

Three branches

  • The Legislature (Parliament) makes laws. MPs are elected under MMP.
  • The Executive (the Prime Minister, ministers and government departments) runs the country and carries out laws.
  • The Judiciary (the courts and judges) decides what laws mean and whether they have been followed.
  • A bill becomes a law

    A proposed law is called a bill. It is introduced, debated, and then usually sent to a select committee, a small group of MPs from different parties. The committee invites submissions from anyone, then reports back with changes. After more debates and votes, the Governor-General signs it and it becomes an Act. Every Treaty settlement, such as the Parihaka Reconciliation Act 2019, goes through these same steps.

    Where you fit

    Anyone, including students, can make a submission to a select committee or start a petition. Councils also consult on local decisions like parks, pools and roads. A good submission is short, says clearly what you want changed, and gives evidence and reasons. Select committees often hear from young people, and some have changed bills because of what students told them.

    No single written constitution

    New Zealand's constitution is spread across many laws, conventions and te Tiriti o Waitangi, not one document like the United States Constitution. That is one reason people still debate what te Tiriti means for how power is shared.
