This law is about oaths, affirmations, and declarations. You will learn what these terms mean and how they are used. The law combines and updates previous rules made by the Parliament of New Zealand. When you make an oath, you promise to tell the truth. You usually do this in a court or other official place. An affirmation is similar, but you do not use the name of a god or higher power. A declaration is a statement that something is true, and you sign it to confirm. The law explains how oaths, affirmations, and declarations are used. It also says who can make them and how they are made.
