The flag of Niue was adopted in 1975. It consists of the Union Flag in the upper left corner with a star in the middle of the Union Flag and four stars forming a diamond around it. It is very unusual for a flag based on a British ensign design, in having not only a yellow background but also a defaced Union Flag in the canton.
The yellow is said to represent the "warmth and friendship between Niue and New Zealand". Some say this exposes the possibility that the designers of the flag did not know the symbolism of the Union Flag in the canton, and simply moved the stars on New Zealand's flag onto the St George's cross.
