There's belief from some that the All Blacks' support for Hīkoi mō te Tiriti is a call for unity.
As halfback TJ Perenara led the pre-test haka yesterday - he referenced the movement opposing the Treaty Principles Bill.
Former Black Fern and Labour MP Louisa Wall says the tradition has evolved over time.
She says it's a team decision who leads - and Perenara wouldn't have been acting alone.
"He obviously talked to his teammates and coach about what the purpose and intent was behind the haka, so that's their choice, surely."
