National MP Judith Collins says we are currently paying "huge tariffs" to get New Zealand beef and lamb into the US.
So even if Trans-Pacific Partnership Agreement deal isn't perfect, it's better to be "in the tent" than stuck outside, missing out.
"Every single deal that we've done on free trade, whether it's Labour or National, we have always got significantly more in the end than what was ever envisaged."
Negotiators are in Hawaii presently, trying to come to a deal before the lengthy US election campaign ramps up.
Labour has serious concerns about the TPPA, particularly what it means for drug-buying agency Pharmac and the secrecy surrounding the talks.
"We're in favour of free trade, and of course we've signed deals, so it's not that we're opposed to them," says Ms King. "I think the real problem with this is we keep being told little snippets of what might be in it, but nobody really knows."
