"God Defend New Zealand" is one of two national anthems of New Zealand, the other being "God Save the King". Legally the two have equal status, but "God Defend New Zealand" is more commonly used. Originally written as a poem, it was set to music as part of a competition in 1876. Over the years its popularity increased, and it was eventually named the second national anthem in 1977. It has English and Māori lyrics, with slightly different meanings. Since the late 1990s, the usual practice when performed in public is to perform the first verse of the national anthem twice, first in Māori and then in English.

New Zealand is one of only two countries in the world—the other being Denmark—with two official national anthems of equal status. The traditional anthem "God Save the King" is generally used only on royal and viceregal occasions. "God Defend New Zealand" is more commonly used on occasions when the national identity of New Zealand is the focus, such as sports events, where it is sung with English and Māori verses. On a few occasions both anthems may be used.
