There is a call for calm over the so-called secrecy surrounding negotiations in the controversial trade agreement - the Trans Pacific Partnership.
Opponents have released a poll saying two out of three New Zealanders think the contents of the deal should be made public before anything is signed.
But NZIER deputy Chief Executive and former trade analyst at the Ministry of Foreign Affairs and Trade, John Ballingall, says New Zealanders have nothing to be concerned about.
"It's certainly not unusual that these negotiations are conducted in the way that they are, behind closed doors.
"We have to trust that our negotiators are going to negotiate a deal that's in our best interests."
More than 500 negotiators from 11 countries are in Auckland this week, for the 15th round of TPP talks.
