"Then there are all the compromises we have to make. On the cost of our medicines, our books and music, for example, will increase over time.
"This Prime Minister and Trade Minister, who have operated under a cloak of secrecy, must not sign this trade deal," Mr Tabuteau said.
Waiariki MP and Maori Party co-leader Te Ururoa Flavell said once he and his party had digested the contents of the deal he would be in a better position to comment.
"There's still a lot of water to go under the bridge. But, where there's issues of sovereignty rights or treaty rights being questioned then you can take it from me that we will not be supporting it," he said.
However, Mr McClay said there were many good reasons the deal should be signed.
"Trade is critical to growth and prosperity in New Zealand - particularly in Rotorua - and free trade agreements level the playing field internationally for New Zealand businesses, large and small.
"There has been a lot of misinformation generated by opponents of free trade. My message to them is that this is a good agreement for the people of Rotorua and New Zealand. Signing this agreement will have an immediate economic benefit."
