(CNN/Meredith) -- A group of firefighters in New Zealand performed a haka to honor the brave first responders who died in the line of duty on 9/11.
The powerful tribute took place outside the Sky Tower in Aukland on Wednesday. After the haka, more than 200 firefighters climbed the stairs of the 52-story tower in memory of their American counterparts.
Scott Brown, the U.S. ambassador to New Zealand, also tweeted a video of the haka, saying: "An appropriate and uniquely Kiwi way to remember the bravery and sacrifice of 9/11 first responders."
A haka is a traditional war dance originally used to intimidate opponents on the battlefield. It was also used when groups came together in peace. In current times, it is often performed to honor guests or during special occasions, like birthdays, weddings or funerals.
