New Zealand is a country in which the legislature chooses the national executive leaders. This is an example of a parliamentary system of government.
Explanation:
Parliamentarianism, also known as parliamentary system or parliamentary democracy, is a system of government in which the choice of government (executive power) emanates from parliament (legislative power) and is politically accountable to it. Modernly, parliamentary systems are mostly either parliamentary monarchies, or parliamentary republics. In parliamentary systems the head of state is normally different from the head of government.
