Auckland Law Revue's been at it again, with its latest parody video tackling race relations.

They have altered the Justin Bieber hit 'Sorry' to mock the lack of a Government apology over the way the Treaty of Waitangi was handled.

Like its takes on Robin Thicke, Lorde and Iggy Azalea, it's proving popular, with tens of thousands of views in just a couple of days.

Spokesman John Kingi said more important than the hits and views it's getting, are the conversations it's sparking.

"New Zealanders - sometimes we don't like to talk about these sorts of issues. But we need to, so that's our hope, that people will engage with it."

"We're hoping that moving forward we can have a much brighter future for all New Zealanders, Maori and non-Maori, and if part of that would be to get a formal government apology, that would be fantastic and we would welcome that."
