One example was the Trans Pacific Partnership, which Taurua has previously spoken against and the Labour-led Government is about to sign.
Taurua said he had been asked to speak in the powhiri for Ardern but Pita Paraone, former chair of the Waitangi National Trust, said no invitation to speak had been issued.
"That's news to me. If he's going to use it as a platform - the same he has used in previous years to incite those of our younger people to protest in the way they have done in recent years then I'm not sure that's a good thing."
He said there was nothing wrong with raising specific political issues but the powhiri was not the place to do it.
"This part of the whole weekend is about welcoming people to Waitangi. It's not about presenting our visitors with what are really political issues."
He acknowledged the people of Te Tii were unhappy with the decision.
"But I don't think they should be surprised given the reaction from the people of the North over recent years. It was timely the decision was made."
Governor General Dame Patsy Reddy was welcomed to the upper marae yesterday without incident and said it was a "new dawn".
However, she was diplomatic about Te Tii saying the powhiri for her there the year before had been "wonderful".
After the powhiri Ardern will visit a local school for a picnic before attending the Navy's Beat Retreat. Tomorrow she will attend the dawn ceremony before hosting a barbecue for the public - her version of Key's more formal Waitangi breakfast for iwi leaders and local dignitaries.
