The flag of New Zealand, commonly known as the New Zealand Ensign, features a blue field with the Union Jack in the canton and four red stars with white borders on the right. These stars represent the Southern Cross constellation, a prominent feature in the southern hemisphere's night sky and a symbol of New Zealand's location in the South Pacific Ocean.
While this flag is not specifically designed for sports teams, it is often used to represent New Zealand in international sporting events, including the Olympics and various world championships. Many New Zealand sports teams use this flag alongside their team logos or emblems to showcase their national identity and pride during competitions.
