Christmas traditions in New Zealand—like those in Australia—incorporate traditional Christian, British and North American Christmas traditions, including biblical and winter iconography, as well as modern and local customs. As New Zealand is in the Southern Hemisphere, the holiday falls during the summer months, so it is often celebrated outdoors with barbeques, picnics, and trips to the beach. New Zealand Christmas dishes include summer fruits and vegetables, a variety of locally-produced meats and seafood, and pavlova dessert. Pōhutukawa are displayed as well as the traditional Northern European tree. Christian church celebrations are held on Christmas Eve and Christmas Day, with carols and hymns sung in both English and Māori.

Christmas traditions in Australia, like Christmas in New Zealand, have many similarities to British, Irish, American and Canadian traditions, including traditional Christmas symbols featuring winter iconography. This means a red fur-coated Father Christmas or Santa Claus riding a sleigh, songs such as "Jingle Bells", and various Christmas scenes on Christmas cards and decorations. However, the timing of Christmas occurring during the Southern Hemisphere's summer season has resulted in the development of some local traditions as a result of the warmer weather.
