A doctors group opposed to the Trans Pacific Partnership Agreement is relieved it is on the brink of being shelved.
Changes needed in the United States to fast-track the signing of the multi-party trade deal have not come about.
New Zealand's Trade Minister, Tim Groser, said another coming vote in the House of Representatives could see the deal delayed for two years.
George Laking, from the group Doctors for Healthy Trade said, just as in New Zealand, there had been opposition to the deal in America.
"People in general have got valid concerns about this deal and the way that it's being negotiated in secrecy.
"I think with this most recent delay in the legislation, I think perhaps the TPP project has reached something of its high-water mark."
He said the negotiations had seen tensions between trade, profit and health.
