The Prime Minister's first international trade trip since the pandemic began has concluded

Ardern and a delegation of 50 spent a week in Singapore and Japan to talk business, tourism and trade with the countries leaders.

Chief Political Reporter Jason Walls says the biggest thing to come from the trip was the security information sharing agreement with Japan.

He says it means information to the top secret level can be shared between the two Government's.

Walls says Ardern was asked if it had anything to do with China's moves in the Pacific, but denied it was.
