Opposition to the Trans-Pacific Partnership seems set spill over to Waitangi Day celebrations in the north, with Te Tai Tokerau MP Kelvin Davis saying a showdown between Ngapuhi would not be a surprise.
He said the Government had failed to explain the deal and Maori felt "kept in the dark."
Ngapuhi elder Kingi Taurua said this week the Government was not welcome at Waitangi's Te Tii Marae because the Trans Pacific Partnership was a breach of the Treaty of Waitangi because Maori had been "left out."
The TPP was concluded in October and effectively gives New Zealand a free trade agreement with the largest and third largest economies in the world, the United State and Japan. It is due to be signed by 12 countries in Auckland on February 4, just a day before Prime Minister John Key and other politicians are due to arrive at Te Tii Marae in Waitangi.
"Why come to Waitangi and talk about the founding document when you don't honour?" Mr Taurua told the Northern Advocate.
