Brian Tamaki's iwi is criticising his involvement in a freedom group which it claims is putting people's lives at risk and encouraging Maori communities to undermine the science.
Te Rūnanganui o Ngāti Hikairo has raised concern about the recent outdoor gatherings and marches it says are run by Tāmaki and Destiny Church and involved a large number of unmasked supporters who went with their babies and tāmariki.
On Tuesday, Wellington CBD came to a standstill as thousands of protesters descended on Parliament to challenge the Covid restrictions.
There have also been a number of rallies, organised by the Freedoms and Rights Coalition, held around the country including in Auckland and Hamilton over the past few months.
But the Rūnanganui is calling on Tāmaki to take a "whānau first" approach and tell his supporters to do everything they can to stem the pandemic.
