Trade Minister Tim Groser is trying to downplay the problems facing the Trans-Pacific Partnership talks after the latest leaking of a contentious chapter and a hiccup in President Barack Obama's plans to get a deal passed smoothly by Congress.
Three previous versions of the intellectual property chapter have been leaked in the past. The latest leak, by WikiLeaks and revealed in yesterday's Herald by Nicky Hager, was from the August round of negotiations.
It showed a gulf between the United States and many of the other 12 countries including New Zealand. Among the contested issues are medicines, copyright and parallel importing.
Mr Groser repeated assurances that Pharmac, New Zealand's state drug-buying agency, was "non-negotiable".
He said there were "wonderful upsides" to the deal and it would lift exports by about $5 billion a year.
