Belief the All Blacks' support for toitu 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.

Wall says he obviously talked to his team about the intent, which is their choice.
