The correct answer is D. Unlike Australia, New Zealand does not have a written constitution.
Explanation:
New Zealand does not have a formal, written constitution. It has a constitutional framework made up of various texts and documents, including certain acts of the Parliaments of the United Kingdom and New Zealand, the Treaty of Waitangi and constitutional conventions. Many constitutional provisions were consolidated in the 1986 Constitution Act. Some made proposals for the establishment of a formal constitution, but there was no serious attempt to adopt one.
