The union representing nurses is asking the Government to allow some public input into the Trans Pacific Partnership Agreement.
Protests were held in 16 centres on Saturday against the trade agreement, which is being negotiated by New Zealand and 11 other countries, including the United States and Australia.
But Trade Minister Tim Groser says they have held numerous stakeholder consultations.
"There've been more discussions with stakeholders on this agreement by a country mile than any trade agreement I've been associated with negotiating in New Zealand in the past 30 years, it's just that these are people taking a very, very politicised view of the matter."
Mr Groser says New Zealanders will hear the facts when the deal is put before Parliament.
