Trade Minister David Parker is heading to Tokyo this week for the first CPTPP meeting since the trade deal came into force at the end of last year.
The meeting would be an early opportunity to bring into effect the Comprehensive and Progressive Trans-Pacific Partnership's (CPTPP) institutional arrangements, Parker said.
"The CPTPP is important in the current uncertain global trading environment. It provides a level of insurance for New Zealand against strains in the multilateral rules-based trading system."
The deal came into force on December 30 last year. It was ratified by New Zealand in October.
The agreement had been the source of much controversy in recent years, with thousands of people taking to the streets in Auckland to protest against the deal in 2016.
