Protesters vowing to cause gridlock on highways tomorrow say they aren't fearful it'll alienate people.

Te Pāti Māori are asking supporters to take to the streets in a nationwide day of action.

It says the Government's policy programmes are an assault on tangata whenua and Te Tiriti o Waitangi.

Te Runanga o Ngai Te Rangi Iwi Trust's Paora Stanley says regardless what Maori do, people will be annoyed at them.

"There's a lot of hate going around as it is. People were going against Three Waters not because of what it stood for, but because it was pro-Māori in their view."
