The Prime Minister's revealed he'll be spending this year's Waitangi Day in the South Island

Chris Luxon's not visiting the Treaty Grounds this week -- instead sending a Ministerial delegation including Erica Stanford, Tama Potaka, Paul Goldsmith and Mark Mitchell.

Luxon's office has this morning revealed he'll celebrate the public holiday with Ngai Tahu, at Banks Peninsula's Onuku Marae.

Luxon's previously said not all Prime Ministers commemorate the day at the Waitangi grounds - and he plans to go to different marae across the country over the course of his tenure in office.
