WATCH: New Zealand Firefighters Perform Emotional Haka to Honour 9/11 Victims

The haka is a traditional Maori war dance used to honour a person or express collective emotion

On Sunday afternoon, New Zealand firefighters held a 9/11 memorial.

During the memorial, they performed an emotional and very powerful Haka, which is a traditional Maori war dance used to honour a person or express collective emotion.

More than 160 of them climbed the stairs of Auckland’s Sky Tower to honour their fallen American comrades who died in the World Trade Centre 15 years ago.
