Maori women have led a protest on the eve of the country's national day, as New Zealand's would-be constitutional revisionist David Seymour delivered an incendiary address at the Waitangi Treaty Grounds.

New Zealand, which on Thursday marks 185 years since its official foundation, is reviewing the place of the Treaty of Waitangi in law, at Mr Seymour's urging.
