"Other countries are pulling out or working to remove investor state dispute clauses from their free trade agreements to avoid these types of lawsuits.
"But this Government continues to play murder ball with our economy in the blind hope that these clauses won't get used when we try to raise our minimum wage, protect our environment or provide quality, affordable healthcare.
"New Zealand First is all for trade with other countries, but we shouldn't be secretly selling our soul inside trade agreements."
Mr McClay, who is Associate Minister of Trade, and Foreign Affairs, said Mr Tabuteau's comparison of trade agreements to a life-threatening disease was silly. "Parliament will have a chance to debate and vote on TPP, as the public will be able to put in submissions to a bill, should the agreement be completed," Mr McClay said.
"The process will be the same as with other trade agreements negotiated by New Zealand governments.
"The Government has been clear that it will only sign up to TPP where it is in the best interests of New Zealand."
Mr McClay said trade agreements helped open up markets for exporters all over New Zealand, including the Bay of Plenty. "For instance, the recently concluded Korean agreement will reduce tariff rates on 99 per cent of wood products, including processed timber, to zero within a short timeframe. Helping our exporters means creating jobs for people in Rotorua and New Zealand.
"Mr Tabuteau should be very mindful of that if he intends to continue his criticism of free trade agreements."
