42 members of the King's Counsel, some of New Zealand's most senior legal minds, are calling on the Government to abandon the Treaty Principles Bill.

The group has written a letter to the Prime Minister and attorney-general Judith Collins outlining their 'grave concerns' about the bill - claiming it 'seeks to rewrite the Treaty itself'.

One of the signatories is Karen Feint KC, and she says the bill will erase several key Treaty principles.

"You can't just rewrite the constitution of New Zealand without having a proper dialogue about it."
