Giving rights to overseas companies that can never be changed regardless of NZ's own needs is a big mistake.
We are constantly assured that the great advantages of extending free trade, particularly with the Americans, will more than offset any minor changes we might have to make as the price of such an agreement. The record of the Trans Pacific Partnership Agreement negotiations shows, however, that - exactly as was to be expected - the Americans see the supposed advantages of free trade entirely in terms of advancing the interests of major American corporations.
The inevitable result? Since co-operative arrangements for handling both exports and imports are regarded by "free trade" zealots as an infringement of the "free" market, what is peddled as a simple free trade deal could require major concessions in the way we organise our exports - through Fonterra or Zespri - and in the freedom we have to negotiate, by using our collective purchasing power through agencies like Pharmac, the best possible prices for imports such as pharmaceuticals.
The leaked record, focusing as it does on intellectual property issues like patents and copyright, pays little attention, however, to one of the main threats from the TPP - the requirement that overseas corporations should be able to sue a future New Zealand government in a specially constituted tribunal if their trading opportunities were to be reduced by future legislation.
Foreign businesses would, as a consequence, have much greater legal rights than any New Zealand enterprise would enjoy, and those legal rights could not be altered, even by a future government elected with a mandate to do so.
