Despite being of a  constitutional nature, some other states have similar properties. In particular, the Kingdom of Denmark consists of Denmark, Greenland, and the Faroe Islands; the Realm of New Zealand consists of New Zealand, the Cook Islands, Niue, Tokelau, and the Ross Dependency. These comparisons are not exact; for instance, aside from the Queen of New Zealand, there is no constitutional structure shared between New Zealand, the Cook Islands, and Niue.
