Hundreds of people have taken to Facebook to post videos of themselves performing a haka to support Standing Rock.
The Native American community of Standing Rock in North Dakota is fighting the construction of a multi-billion dollar oil pipeline through their land.
There are concerns a leak in the pipeline would pollute the tribe's only water supply.
Maori across the country and across the world have been spured into action after a moving haka was performed at the frontline of the protest.
Gisbourne local Te Hamua Nikora created a haka and a Facebook page in support of the indigenous tribe fighting for their rights.
It now has almost 15,000 members.
Videos of Mr Nikora's haka and others have been posted all over social media.
Indigenous rights attorney and activist Sherri Mitchell shared a video of four children from Te Kura Kaupapa Maori O Te Ara Rima school in Hamilton.
The Wellington Primary school Kapa Haka competition also shared their haka online. The judges of the competition led the haka and encouraged the children to join in.
