New Zealand will deploy a patrol aircraft to support the monitoring and surveillance of illegal ship-to-ship transfers by North Korea, Japan’s foreign ministry announced on Tuesday.

In a press release, the ministry stated that a Royal New Zealand Air Force (RNZAF) P-8A Poseidon aircraft will operate from Kadena Air Base in Okinawa from mid-April to early May, the sixth time the RNZAF has contributed to monitoring North Korea’s illicit maritime activities in violation of U.N. Security Council sanctions since 2018.
