Hello there, This is the flag of New Zealand and I want you to know what it symbolizes.
The union Jack represents New Zealand's British commonwealth heritage. The Blue background symbolizes the sea and sky. The four stars symbolizing the constellation the southern cross, represent the stars Alpha,Beta,Gamma and Delte. The southern cross is a prominent constellation in the southern hemisphere, and represents New Zealand's geographical position to the rest of the world.
